2. The questions you ask are rather messy, I'll try to answer them< On the adjustment of balance of payments imbalance:
when the balance of payments is unbalanced, that is, when there is a deficit or surplus, it will have a lot of adverse effects on a country's economy, so it is necessary to take policy measures to adjust it to restore balance. The common balance of payments adjustment policies are: foreign exchange buffer policy, monetary and fiscal policy, exchange rate policy and direct control policy
the question you are asking should be the foreign exchange buffer policy, that is to use the change of foreign exchange reserves or temporary borrowing to offset the excess foreign exchange supply and demand to adjust the balance of payments. When there is a deficit, the import volume is larger than the export volume, the demand for foreign currency increases, the monetary authorities rece foreign exchange reserves, sell foreign exchange in the foreign exchange market, or temporarily borrow money to make up the foreign exchange supply gap; When there is a surplus, that is, when the export volume is greater than the import volume, the foreign currency supply increases, then the monetary authority will purchase foreign exchange in the foreign exchange market, increase foreign exchange reserves and eliminate excess foreign exchange supply
on foreign exchange conversion
when you say that the transaction should be converted into foreign exchange, you should refer to the foreign exchange control policy, which is also one of the policies of balance of payments adjustment. On December 1, 1996, China officially accepted the eighth article of the agreement of the International Monetary Fund, realizing the convertibility of RMB in current account. At the end of 2004, according to the 43 capital transactions determined by the International Monetary Fund, the, In China, 11 items are convertible, 11 items are less restrictive, 15 items are more restrictive, and 6 items are strictly restrictive
about money supply and interest rate
as mentioned above, monetary policy is also one of the policies to adjust the balance of payments imbalance, and monetary policy is to adjust the money supply, open market business, rediscount and legal deposit reserve ratio, which are the three traditional monetary policy tools. When you trade with a foreign manufacturer, the foreign manufacturer pays you foreign exchange (usually US dollars). According to China's current policy, you can't get these US dollars directly. You can only get them out by changing them into RMB at a designated bank or institution. At this time, the state is equivalent to taking away these foreign exchange (becoming foreign exchange reserves), Then according to the exchange rate to pay you RMB (increased the money put in), this is the process of foreign exchange reserves increase in foreign trade. There is no direct link to interest rates. Interest rate is one of the important means to adjust the exchange rate, and the exchange rate policy is also one of the policy tools for the government to adjust the balance of payments.

N90 is a mobile phone with many parts that can be rotated. It is not only the camera mole of the 2 megapixel Carl Zeiss optical certified autofocus camera, but also the exquisite screen of the phone. However, unlike those procts that only rely on "rotation" to attract eyeballs, the top cover of the N90 has only a counterclockwise rotation direction, and the angle is as small as 135 degrees, so it can't be completely outward and closed
in addition, N90's camera software is very "sensitive", as long as the screen has a slight rotation angle, it will automatically start and enter the viewfinder state, which seems unnecessary
N90 has been used in NOKIA's Symbian operating system and Series60 platform. Among the few smartphones that can be used to make the keyboard symmetrical, the C and pen keys are more and more popular. The contact area has been exactly the same as the following numeric keys. p>
and the control direction is not the rocker with relatively inaccurate positioning. Instead, it is the navigation key with metal texture, and the white plastic confirmation key is embedded in the middle. The good key range and the feedback force create a comfortable use feeling
4. Nokia N900 is a 3G smartphone with Maemo 5.0 operating system released by Nokia on August 27, 2009. Nokia officially claims N900 as a mobile computer. Nokia N900 adopts arm architecture, with a main frequency of 600MHz, 1GB program memory (including 256MB ram and 768mb virtual memory), Linux based Maemo 5 operating system, and 3D graphics accelerator to support OpenGL es 2.0. Nokia N900 is the fourth multimedia network terminal based on Linux platform launched by Nokia after Nokia N770, Nokia N800 and Nokia N810. It adopts sideslip design, has a 3.5-inch touch screen, and the screen resolution reaches WVGA (800x480 pixels). In terms of hardware, the Nokia N900 is equipped with an omap3430 CPU with a frequency of 600MHz. The N900's camera has a 5 megapixel Carl Zeiss lens and can shoot 800 pictures × 480 pixel high definition video in AVC / H.264 format. In addition, the operating system of the mobile phone will be Maemo 5 OS based on the underlying Linux platform instead of Symbian S60 on N97. Maemo 5 version of the system provides 3G network support, can access the Internet anytime and anywhere, and can make VoIP calls through WiFi network. In terms of software, N900 supports multi task processing at the same time, has built-in Firefox 3 browser, supports flash 9.4, and other functions are not very different from a mature smart phone, GSM mobile phone sliding cover main screen size 3.5 inch main screen material TFT main screen color screen, 16 million color main screen parameters 480 × 800 pixels (WVGA), touch screen memory capacity 1gmb ROM, 32g NAND standard configuration 1320mah lithium battery, manual, charger shell color, black volume 111 × fifty-nine point seven × 18.2mm weight 180g [edit this paragraph] basic functions: ring tone supports MP3, AAC, AMR, wma, chord and other formats, address book group management, business card type management information function, SMS, MMS SMS, SMS group sending, e-mail receiving and sending, e-mail, SMTP, POP3, IMAP4 and other mail protocol input method, QWERTY keyboard input, handwriting input, English input method, game built-in game, Support N-Gage game, office function (word, Excel, PPT), Adobe PDF recording function, support recording function, main functions include built-in antenna, clock, built-in vibration, scenario mode, call time prompt, hands-free call, standby picture, call picture recognition, call ring recognition, call firewall, voice dialing, changeable shell, three defense function, flight mode, Theme mode, additional functions, gravity sensing function, alarm clock, shutdown alarm clock, calendar, calculator, calendar, memo, voice memo, world clock, currency conversion, unit conversion, timer, stopwatch, automatic keyboard lock, automatic switch on / off, business card scanning function, electronic dictionary support electronic dictionary [edit this paragraph] data application function, Bluetooth support, Bluetooth V2.0, EDR support, A2DP Bluetooth stereo data service, GPRS, edge, HSDPA, Java, Java, MIDP 2.0, CLDC 1.1, WAP, WWW browser, data cable, data cable, micro USB interface, USB 2.0, driveless USB disk function, 3.5mm headset interface expansion card, microSDHC card, hot plug, up to 16GB, WiFi (WLAN) and WiFi, Support 802.11b/g GPS positioning system, support GPS, built-in GPS navigation chip, support A-GPS network auxiliary navigation function, other data functions, built-in modem [edit this paragraph] special camera, built-in camera, Carl Zeiss certified lens camera, pixel 5 million pixel sensor type CMOS sensor, sub camera, built-in sub camera flash, built-in flash, Dual LED flash shooting mode can choose 5 kinds of white balance: automatic, sunny, cloudy, incandescent, fluorescent, optional 7 kinds of situational mode: automatic, user, macro, sports, night, vertical, horizontal, night, vertical photo quality support maximum 2592 × 1944 resolution photo shooting photo effects: normal, nostalgic, black and white, negative, bright shooting, characteristic digital zoom, auto focus video shooting, audio video shooting, maximum support 800 × 480 pixel video recording [edit this paragraph] multimedia entertainment function, multimedia flash function, 3.5mm headphone interface, e-book MP3 player, MP3 player, MP3, wma, ACC and other formats, video player, MPEG4, h.264/avc, h.263/3gp, realvideo and other formats, flash 9.4
5. Nokia N900
let's briefly review the N900: the Nokia N900 adopts a full keyboard slide design, with a 3.5-inch WVGA level (480x800 pixels) 16 million color TFT LCD screen. Equipped with the latest developed maemo5 intelligent operating system, with 600MHz arm cortex-a8 processor, and supporting powervr SGX with OpenGL es 2.0 high-performance graphics processing technology, it has a very gorgeous operation interface and powerful multi task operation ability. With powerful music and video playback capabilities, with a 5 megapixel autofocus lens
Nokia's appearance design has always been the most criticized part of its procts. Not only has the N900 not changed in this aspect, it seems that it has intensified, further explaining the bloated. In addition to the increase in width compared with N97, the weight has reached 181g, which is much higher than the 150g of N97. The size of 110.9x59.8x18mm is not small for a mobile phone. The wide and thick N900 is hard to weigh and light whether it is controlled by one hand or placed in the trouser pocket
Nokia N900 / N97 appearance comparison
both adopt the full keyboard side sliding cover design, which reces the size difference after opening the side sliding keyboard. The original bracket design on N97 is not used on N900, but the more traditional smooth design, which can not lift a certain angle like touch pro2, and the user's perspective is not careful enough. However, the advantage of the traditional side sliding method is that the stability is more reassuring, and there is no need to worry about whether the N97 bracket "will not be firm"
Comfort: iPhone 3GS & gt; Nokia N97 & gt; Nokia N900
in addition to the difference in the angle of the sideslip screen, the design of the full keyboard is also different. Although the layout of the two buttons is designed in three rows, e to the upwarping of the side sliding screen, the space between the top case of N97 and the screen is slightly larger, and the operation space is wider. The N900 is a bit crowded, but for ordinary users, this space rection will not affect the normal operation, so there is no need to worry too much< At the top of the screen, there are microphone, front camera, light sensor and distance sensor. We are very familiar with these components, and they are also essential items for mainstream high-end mobile phones. In particular, the distance sensor is particularly important for a touch mobile phone. It can automatically control the switch of the screen according to the distance between the face and the screen in the process of calling, so as to save power and avoid misoperation. In terms of microphone area, N900 is a bit more shy than N97. In actual calls, it does affect the volume. The volume is not very large
the N900 at the bottom of the screen is empty
at the bottom of the screen, the N900 does not have any physical buttons. Presumably, this is also to better explain the concept of full touch. However, it seems more convenient for users to configure dial-up / hang up and main menu keys like N97
compared with the very detailed parameter identification on the N97, the Nokia N900 is as low-key as the N97 Mini in this respect. Only the words "arm cortex-a8", "32GB" and "designed in Finland" are reflected. Of course, the most important one is the "arm cortex-a8" processor
on the right side of the fuselage, the N900 has more buttons than the N97. In addition to the volume increase / decrease and photo taking buttons, there is also a power button in the center, which can be used to switch on / off and control the screen
at the bottom of the fuselage, the N900 is still more abundant. In addition to the stylus, microphone, 3.5mm headphone interface, and hold key, there is an independent speaker, and the opposite top is also designed with the same speaker. Although the N97 also adopts a similar al speaker design, the al speaker effect of the N900 is still better, The volume and sound effect are very good when playing out
the left side of the N900 is very clean and does not involve any buttons or interfaces, while the N97 involves al speakers, microusb and hold buttons here. The result should be related to the operation mode of the N900 itself. Because the N900 only supports horizontal screen operation in most cases (except the dialing interface), it is not difficult to understand that there are no more buttons and interfaces on this side
the top of N900 is designed with loudspeaker, micro USB interface and hanging rope hole, while N97 is designed with 3.5mm interface and power key. Let's review it for a moment, and praise the 3.5mm headphone interface and micro USB interface (both data and charging are available) which are the most common and the most mainstream at present, because they will bring a lot of convenience for users' daily use
one of the most important reasons why N900 has attracted much attention is that it does not continue the S60 platform commonly used in N series procts, but adopts the latest maemo5 platform. Maybe many users are still unfamiliar with this system. In fact, Maemo is a new system developed by Nokia based on the Linux open source mobile device platform. Compared with the cumbersome Symbian code, Maemo can provide developers with a convenient and practical development environment, support multiple business models, and easily realize the mobile processing of existing desktop solutions, As we know, the Nokia N810 and N800 are representative models adopting Maemo platform
in fact, Nokia's launch of Maemo 5 platform and N900 is also a helpless move. In the face of the booming Apple iPhone,
the dazzling sliding unlocking interface,
at the moment of opening the Nokia N900, we are attracted by the shocking screen effect beyond the past. The sliding unlocking method is suspected of learning from the iPhone, but the effect is still quite good. Unfortunately, the maemo5 system can not support multi touch technology at present, and the N900 is also equipped with a resistive touch screen, so the operation feel is still a little lower than that of a capacitive screen. However, there is no big difference in fluency after familiarity<
display and management of multiple home screens
one of the standby interfaces of Nokia N900
friends familiar with the current mainstream smartphone operating systems all know that touch flo / sense in Windows Mobile, touch sense or OMS in Android, Mac OSX of iPhone all use multiple home screens as the scattered places of many applications, To achieve the purpose of effective classification and convenient application, it is particularly important for the increasingly rich mobile phone applications, but the previous S60 does not have such a function<
one of the Nokia N900 standby interfaces
one of the Nokia N900 standby interfaces
and maemo5 also adopts the same concept, which presents the standby interface in the way of multi screen switching. With the help of touch operation, it is convenient to slide left and right to complete the main screen flip. Click the blank area of the screen to select the program, bookmark, contact, widget, theme, etc. to be added from the pop-up settings - "Desktop Menu" to complete the personality setting of the current home screen. Users can have up to four main screen interfaces and at least one. The selection and setting of the home screen is similar to Android system. Long press the icon to drag or delete it
Nokia N900 menu interface
although there is not much relationship between the maemo5 system and the S60 system, in order to take care of the habits of old users, Nokia uses the S60 system in the design of program menu icons, so that users familiar with the S60 can easily find a sense of belonging in Maemo, and it is easier to get started. The number of programs displayed on a single screen is limited. Users can click more in the lower right corner to get more program lists<
powerful multi task processing
powerful multi task manager
for an intelligent platform, the running and processing ability of multi task is a very important indicator of its overall performance, especially for the mobile phone, which has more and more applications, the processing ability of multi task will have a great impact on the daily use of users. Maemo5 system has powerful multi task processing capability. When we run a program, we will pop up two icons on the left and right sides of the screen. The box on the left represents "multi task switching", and the small X on the right can "close" the current program. If the user doesn't want to close the current program and wants to start a new one, click the small box in the upper left corner to enter the multitask switching management interface as shown in the figure above. Here we are very convenient to switch or close the running program, and the whole process can be said to be very smooth
storage details
Nokia N900 has built-in 600 MHz arm cortex-a8 processor of Ti OMAP 3430, supports powervr SGX with OpenGL es 2.0 high-performance graphics processing technology, and is on the same level as Apple's iPhone 3GS. In addition, the N900 also has 256 MB ram and 768 MB virtual memory, with a built-in mass storage space of up to 32GB, which can save 7000 pieces of MP3 music or 40 hours of high-definition video for users. With the help of 16GB capacity microSD memory card, the storage space can be increased to 48gb
running more than ten programs at the same time
from the actual use, the running speed of the machine is quite smooth, even in the case of opening more than 10 background programs at the same time, it still maintains a stable and fast running speed, and when running some programs, its speed even exceeds that of the iPhone 3GS. Although the main frequency of 600 MHz processor is not as good as that of some windows mobile monsters with 1GHz processor at present, Maemo system is still very effective in resource utilization from the actual use effect. The operating frequency of 600 MHz is comparable to that of 1GHz WM monsters
the N97 uses a 434MHz arm 11 processor with 128MB ram and 32GB memory. Although it can't compare with N900 in processor frequency and memory, in S60 system, this configuration can fully meet the needs of users<
WVGA HD video playback
thanks to the powervr SGX with OpenGL es 2.0 high performance graphics processing technology of the 600 MHz arm cortex-a8 processor of Ti OMAP 3430, the Nokia N900 has a very strong video decoding capability. With a 3.5-inch WVGA level (480x800 pixels) 16 million color TFT LCD screen, it can perform a very shocking 16:9 HD video playback
can only play 360 × N97 with resolution below 640 is naturally inferior to that of N97
5 megapixel Carl Zeiss lens
mode selection
although the Nokia N900 is not equipped with a camera above 8 megapixel level as expected, it still basically maintains the water level of N97, with a built-in 5 megapixel Carl Zeiss camera, The maximum aperture and focal length are 2.8 and 5.2 respectively (N97 focal length is 5.4). In addition to supporting automatic mode, it also provides four modes including macro mode, portrait mode, sports mode and landscape mode. In addition, the machine also supports white balance, exposure compensation, ISO sensitivity adjustment and other functions
evaluation summary: after multiple comparisons in appearance, function and configuration, we have a comprehensive understanding of these two procts

after Sony Ericsson u5i, the u8i is another model that supports 720P HD video recording. At present, there are few models with such parameters on the market. Sony Ericsson u8i adopts a fashionable side sliding full keyboard design, is equipped with S60 Fifth Edition operating system, supports WiFi, GPS and Bluetooth functions, and is equipped with micro USB port and 3.5mm headphone interface. The back is equipped with a 5 megapixel camera, and the screen is still a 3.2-inch resistive screen
in addition to having one more keyboard than u5i, Sony Ericsson's u8i has also reced its camera configuration from 8 megapixels to 5 megapixels. This is probably to rece the price difference between u5i and u5i, so that you can really choose the same price
Sony Ericsson u8i also uses a 3.2-inch NHD (360x640 resolution) TFT display with 16 million colors, which is very realistic and bright. But it's still a resistive screen, and you still need to press it down when you operate it. The visual angle is very wide, basically can reach more than 170 degrees.
