The collection and analysis of Tiangong by Zhuxian hand has been popular with the majority of players since it was launched, so what are the interesting ways to play in the collection and analysis of Tiangong by Zhuxian hand? Let's take a look at the relevant strategies of the collection and analysis of Tiangong by Zhuxian hand with Xiaobian ~

for the collection and analysis of Tiangong by Zhuxian hand In fact, it's very interesting to visit Tiangong collection by Zhuxian hand. When it comes to Tiangong collection, the first thing that comes to mind is hunting. I won't talk about the low-level one. The level five one is in 100000 mountains. When you open the map, there are four leather like icons. It's very important to find a point where there is no one to hunt. Here, I want to emphasize that all the natural labor collection must use props in order to yield. I have experimented with it myself. When I am full of physical strength and do not use props, there are only about 10 half life materials, and there can be as many as 20-40 props, so I still use crystal Skinner for hunting

Then there is the use of physical strength and the golden five minutes of this prop. I have two ways to pluck the skin in hunting. Method 1: hit 4 with group attack skills, and collect two pig skins at a time. If this method doesn't interrupt, it will cost 470-480 physical strength in 5 minutes, and the hard fur looks like 42

Method 2: first hit two, and then hit two after collecting. Two group attack skills are used in turn. In this way, continuous collection can be achieved. I take Qingyun as an example. At the beginning, they cut two, and then frost and Sheng Bing take turns. These two skills take 12 seconds and 15 seconds each. In this way, the collection of props for 5 minutes to maximize the consumption of physical strength, access to materials. This collection takes 510-520 minutes. There are more than 45 fur

Second, fishing! Basically, I start to fish from above 170 points of physical strength. In this way, I just need to buy a 5-minute crystal fishing rod once, and I almost run out of physical strength. Of course, you need to point the highlight area all the time and hang it like this. The baby can't bear it. You can save more physical strength and then fish, but you can't do it less. You have to use Yuanbao to buy both physical strength and fishing rod. If you don't use physical strength for a few seconds, the baby will be distressed

Finally, mining is the simplest way to hang up the whole process. There is no need for manual operation. The control of physical strength is similar to fishing. Save 170 points of physical strength to start mining. The five minute hoe only needs to buy one physical strength, and then it will be used up. Another point is to remind you that when you run out of props, you stop collecting them, because it's really not worth it. If you don't give them away, you can save them for the next time. There are really few things to collect without props

2. Flow rate of ore. Upload the free bandwidth to get the ore, and the digital currency fast currency obtained from ore transaction can be withdrawn.

3. Level 1-4: level 30
Level 5: level 40
Level 6: level 50
Level 7 or above is level 70
Life players spend a lot of time

4. Mining skills need characters to reach level 50 to be promoted if your mining quantity is full.

5. Level 8 mining in Wuyi, skill level should also be level 8! Now, it's easier to rush. Many new maps can mine! Like seven levels of increased Qingyuan, nine and ten levels of digging everywhere! However, only Wuyi had grade 8

6. If you're doing it all day long, you'll have to do it for half a year. Anyway, the proficiency is nearly 3000. I used to do it for three months with fishing. If you have any assistance, it's only a month

7. Building owner
upgrade after level 40 according to the number of times you dig

In the study of trace element geochemistry, the distribution coefficient is one of the core problems. Without the distribution coefficient data, the quantitative model of trace elements can not be established. The Nernst partition coefficient or simple partition coefficient mentioned above is quoted or discussed in general geochemical literature. It refers to the equilibrium concentration ratio of trace elements between two phases (crystal mineral and liquid melt in most cases) at constant temperature and pressure. According to Nernst's law, the partition coefficient should be composed of two parts: the concentration of trace elements in solid phase (crystalline phase) and liquid phase (matrix) in equilibrium system. In order to measure the concentration of trace elements in these two phases and obtain the partition coefficient, there are two most commonly used methods: direct determination and experimental determination

The direct determination method is also called phenocryst matrix method, which is to determine the distribution coefficient by determining the content of elements in rock phenocryst and matrix. It is not easy to determine the partition coefficients in systems related to magmatism and metamorphism. In fact, little progress has been made before the 1950s. The early determination mainly used the direct determination of natural substances. That is to say, the concentration of elements in two equilibrium coexisting phases of geological body is directly determined, and the distribution coefficient of elements is calculated according to Nernst distribution law. The phenocrysts represent the solid phase in the process of melt crystallization, and the matrix represents the liquid phase, i.e. the magma melt. The ratio of trace element concentration in the two phases is the distribution coefficient of the element. Determination of phenocryst minerals and matrix of volcanic rocks (melt in equilibrium with minerals), or determination of minerals and quenched melt (glass) in lava flow, and determination of coexisting minerals in rocks (mineral / mineral partition coefficient of elements). The method is simple and easy to operate, and provides the approximate concentration range of the distribution coefficient of trace elements. Although the variation range is large, the order of magnitude remains unchanged. The existing problems are as follows: 1) it is difficult to prove whether the whole phenocryst and melt have reached equilibrium, such as the zonal distribution of common crystal growth components in minerals. Although the main components are homogeneous, the concentration of trace elements is zonal, indicating that the equilibrium is incomplete, so the distribution coefficient measured can only be effective or apparent, but not equilibrium; ② It is difficult to obtain pure minerals by manual or magnetic separation, and it is easy to cause matrix pollution for incompatible elements. For transition elements, it will cause trace opaque minerals to be mixed, resulting in wrong distribution coefficient; ③ It is difficult to know under what conditions (temperature and pressure) the system reaches equilibrium and whether the existing phenocrysts have undergone rebalancing or alteration ring magma cooling and upwelling. Since the 1960s, many scholars have devoted themselves to the determination of partition coefficients by experimental methods

Experimental determination method through the experiment to make a mineral and a liquid (melt or solution) in equilibrium, or make two minerals reach equilibrium, so that trace elements in the two phases to achieve dissolution equilibrium, and then determine the concentration of elements in the two phases, get the distribution coefficient. It can be divided into two methods: chemical reagent synthesis and direct use of natural materials

The second is that it is difficult to separate the mineral from the phase rich in trace elements, and it is also difficult to remove the impurities formed around the crystal ring quenching. The concentration of trace elements used in the experiment will be much higher than that of natural system, which may not be completely suitable for dilute solution system. Wood & Fraser (1978) pointed out that when the element partition coefficient is greater than 1 and obeys Rayleigh fractionation law, the pseudo partition coefficient is greater than the equilibrium partition coefficient. However, if the zonal change of crystal composition is e to the slow diffusion of material in the melt to the growing crystal, the pseudo distribution coefficient will have an abnormally low value. When applying the partition coefficients of trace elements obtained by total analysis of coexisting phases (i.e. single mineral analysis), special attention should be paid to the above conditions. However, they also pointed out that despite the above problems, the pseudo partition coefficient is more accurate than the real equilibrium partition coefficient in reflecting the behavior of elements in the real geological system

The main reasons are: 1) the purity of the sample; 2; ② Uniformity of samples; ③ Whether the balance has been reached; ④ Analysis error

the purity of sample is the first factor of data error, especially for direct determination. For example, the microinclusions in accessory minerals are easy to cause errors in the distribution coefficient. For example, silicotungenite, a by-mineral containing REE, is considered to be the main pollution source of the main mineral, which seriously disturbs the partition coefficient. Cameron & Cameron (1986) reported that epidote, a accessory mineral, greatly affects the REE partition coefficient between amphibole and volcanic glass, including the generation of obvious Eu anomaly. Considering the role of amphibole in the melting process, such a change should be e to the disturbed partition coefficient of amphibole and inclusion, rather than the partition coefficient of pure amphibole (Fig. 5-3)

Fig. 5-3 distribution coefficient of REE between amphibole and volcanic glass

(according to Shaw, 2006)

e to the existence of tiny epidote inclusions in the sample, EU is significantly abnormal, resulting in the distorted distribution coefficient curve of determination

the uniformity of the sample should also be concerned. If the composition of a mineral changes from the core to the edge, the composition of a ground sample cannot quantitatively reflect this change. In addition, this change in composition also indicates a third concern, that is, the chemical equilibrium has not been achieved

In recent decades, the rapid development of analytical methods and technologies, especially the progress of micro beam analysis technology, has greatly improved the quality of partition coefficient measurement, such as modern high-precision micro area measurement technologies such as electron microscope (EMP), ion probe (SIMS) and laser ablation inctively coupled plasma mass spectrometry (LA-ICP-MS), Low or trace element content analysis can be carried out in a mineral or a glass matrix on a polished sheet, and even fluid and melt inclusions with the size of several to tens of microns can be determined to determine the partition coefficient, without the need for physical separation of the sample (zajacz et al., 2008). The experimental measurement of partition coefficient has also been greatly improved. The experimental synthesis technology under high temperature and high pressure has been improved. The application of microbeam technology in this field also has a good prospect

figure 5-4 shows the comparison of the partition coefficients of three trace elements between plagioclase and glass determined earlier and later by Bindeman et al. (1998). Taking RB as an example, the variation range of early data is more than three orders of magnitude, which is useless in the quantitative simulation of trace elements. The new data measured by ion microprobe has a good linear relationship with the content of anorthite in plagioclase

Table 5-1 and table 5-2 are the partition coefficient data of some elements. More detailed data can be found in Irving (1978), rollinson (1993) and Zhao Zhenhua (1997)
