1. It should be pointed out that MIUI does not provide a unified "one click to close advertisement" button (nonsense), but some advertisements can be closed separately. Let's practice it as follows:

"folder" is relatively simple. When creating a folder, you will be prompted to close it if you like

"weather" is a weather related recommendation. The switch to turn off is in the upper right corner. After clicking in, there is the option of information flow setting. Turn off the weather consultation switch in it

"calendar", pull to the bottom, there is a card management, you can turn these off one by one
in addition to these, we haven't found a way to close music and videos. If you have any good ways, you might as well contribute and share them.

The calculation method is as follows:

pressure = pressure / compression area (P = f / s)

pressure = pressure * force area (F = PS)

main unit

A. pressure
international unit: "Newton", abbreviated as "cow", symbol "n"

B. pressure

international unit: "Pascal", abbreviated as "pa", symbol "pa"

converted 1 pa = 1n / m2

1 MPa = 145 psi = 10.2 kgf / cm2 = 10 bar = 9.8 ATM

1 psi = 0.006895 MPa = 0.0703 kg / cm2 = 0.0689 bar = 0.068 ATM

1 bar = 0.1 MPa = 14.503 psi = 1.0197 kg / cm2 = 0.987 ATM

1 atmospheric pressure (at M) = 0.101325 MPa = 14.696 psi = 1.0333 kg / cm2 = 1.0133 bar

1 mmHg = 133.33 PA

The conversion relations of several common pressure units in engineering are as follows:

1MPa = 106pa ≈ 145psi ≈ 10.2kgf/cm & # 178

1kgf/cm²= 98.067kPa≈98kPa

1psi1bf/in²= 6.8948kpa ≈ 6.9kpa

1mmh2o = 9.8067pa ≈ 9.8pa

extended data:

pressure in physics refers to the force acting vertically on the surface of an object. The stressed object is the supporting surface of the object, the action point is on the contact surface, and the direction is perpendicular to the contact surface. When the stressed object is a horizontal surface, the pressure (f) = weight [please note that it is different from the mass (g), g = mg]. In this case, the unit of pressure is Newton

The English full name of

psi is pounds per square inch

P is pound, s is square, I is inch

It can be calculated by changing all the units into metric units: 1bar ≈ 14.5psi

1psi = 6.894757kpa = 0.0689476bar

in Europe and the United States and other countries, it is customary to use psi as the unit

in China, we generally use "kg" to describe the pressure of gas (instead of "kg"), the unit is "kgf / cm2", a kilogram of pressure is a kilogram of force acting on a square centimeter

The unit commonly used in foreign countries is "psi", and the specific unit is "lb / in & #", It's "LBF / in 2," which is like the Fahrenheit scale (?)

In addition, there are PA (Pascal, one newton acting on one square meter), kPa, MPa, bar, mmh2o, mmHg and other pressure units

1bar = 0.1MPa = 100KPA = 1.0197162 kgf / cm2

1standard atmospheric pressure (ATM) = 0.101325 MPa = 1.01325 bar

because the unit difference is very small, if it is not to be calculated accurately, it can be written as follows:

1bar = 1standard atmospheric pressure (ATM) = 1kg f / cm2 = 100KPA = 0.1MPa (MPA)

3. No, because you will refuse a refund

if the buyer doesn't apply for Taobao intervention, you can apply for Taobao intervention after the 15th day of the refund application
after Taobao primary two intervenes, it will be processed and judged according to the vouchers and rules of both parties.

4. Hi
hello. It is not recommended to uninstall the security center, mobile manager, system update and other moles, otherwise the system may be unstable.

5. Calculation of gas pressure: formula PV = NRT, where p is the pressure, V is the gas volume, n is the mol number of the gas, R is a constant, t is the temperature. It can be seen that when the temperature and the mol number of the gas remain unchanged, the gas pressure is inversely proportional to the gas volume

6. I've met a very generous buyer. At that time, I was worried for a long time, and I didn't return it until a few days later
I didn't rule out the scam, and I made it clear that no matter whether the other party returned or not, there was evidence

7. Formula: PF / S P - pressure Pascal for short, F - pressure Newton for short, n s - stressed area - square meter indicates that when a pressure and pressure object deforms e to external or internal factors, there is an interactive force between the two sides of any section in it, and this force on the unit section is called stress. Generally speaking, for solids, under the action of external force, there will be compressive or tensile deformation and shear deformation. Therefore, to describe these deformations of a solid exactly, we must know the effect of the three components of the force acting on its three mutually perpendicular planes. In this way, the stress f / A has nine different components corresponding to each component force FX, FY, FZ acting on three mutually perpendicular planes ax, ay, AZ, so strictly speaking, the stress is a tensor. Because the fluid can not proce shear, there is no shear stress. Therefore, for the static fluid, no matter how the force acts, there is only a force perpendicular to the contact surface; And because the fluid is isotropic, the forces acting on a unit area are the same at the same point, regardless of the orientation of these surfaces. Since f / A is constant in all directions at every point of an ideal fluid, the directionality of stress f / A does not exist. Sometimes this kind of stress is called pressure, which is called pressure in middle school physics. The pressure is a scalar. The application of the definition of pressure is always limited to the problem of fluid. Pressure acting vertically on a unit area of an object. If P is used to express the pressure, the unit is Pascal (1 Pascal, 1 Newton / square meter). For the definition of pressure, we should pay attention to four points: (1) when the stress area is fixed, the pressure increases with the increase of pressure (2) if the same pressure acts on the surface of the support, if the stress area is different, the pressure will be different. When the stress area is small, the pressure is large; When the stress area is large, the pressure is small. (3) pressure and pressure are two completely different concepts: pressure is the force on the support surface and perpendicular to the support surface, which has nothing to do with the area of the support surface. Pressure is the pressure on an object per unit area. (4) the unit of pressure and pressure is different. The unit of pressure is Newton, the unit of general force is the same. The unit of pressure is a compound unit, which is composed of the unit of force and the unit of area. In the international system of units is Newton / square meter, known as "Pascal", referred to as "pa". ③ When the stress area is fixed, the greater the pressure is, the more obvious the effect of pressure is When the pressure is constant, the smaller the force area, the more obvious the effect of pressure In this case, the pressure is inversely proportional to the area under force) the physical meaning of 51pa: the pressure on an area of 1 square meter is 1n. 1pA size: the pressure of two pieces of paper on the horizontal table. Note: when the contact area between the equidensity cylinder and the contact surface is equal, P = ρ GH p - liquid pressure PA ρ— Liquid density kg / m3 kg / m3 g-9.8n/kg, usually 10N / kg

9. The fluid with pressure can do work, and the pressure of the fluid becomes smaller after doing work. We call the work ability of the fluid with pressure as pressure potential energy
in the Bernoulli equation of fluid
ρ gz1+p1+ ρ v1^2/2
= ρ gz2+p2+ ρ In V2 ^ 2 / 2
+ PW
, P1 and P2 represent the pressure potential energy of the two cross sections.

You can operate in the following way:

1. We open the settings, find the system application in the device, and click in, as shown in the figure below

but there are still some small advertisements embedded in the application system that can't be deleted and won't bring too much impact. There are also some functions such as weather information function recommendation and SMS intelligent recognition, which still have some substantive effects on us, so setting on demand can bring better experience
