Program development of the middle layer, temperature of the middle layer

Because the lower part of the middle layer is the stratosphere, where there is a lot of ozone, absorbs a lot of ultraviolet rays, and the temperature is very high, so the lower part of the middle layer is hotter; There is little ozone in the mesosphere, and nitrogen and oxygen can absorb short-wave radiation, but the heat absorbed in this way is absorbed by the upper atmosphere, so the degree above is low.

The temperature in the mesosphere decreases with altitude, and decreases about 100 meters of ascent. Due to the great influence of the land surface, the horizontal distribution of meteorological elements (temperature, humidity, etc.) is uneven. The mixture of regular vertical movement of air and irregular turbulence is quite strong.

The upper and lower layers of water vapor, dust, and heat are exchanged and mixed.

1. The temperature decreases rapidly with the increase of altitude, and the temperature at the top of the middle layer drops to 83 113. Because the ozone content in this layer is very small, it cannot absorb a large amount of the sun's ultraviolet rays, and most of the shortwave radiation absorbed by nitrogen and oxygen is absorbed by the upper atmosphere, so the temperature decreases with the increase of altitude.

2. There is a strong convective movement, also known as the upper-level troposphere or upper troposphere. This is due to the convective movement of the air due to the cold in the upper part of the atmosphere and the warm lower part of the atmosphere. But due to the thinning of the air in this layer, the convective movement of the air cannot be compared with the troposphere.

The atmosphere from the top of the stratosphere to between 85 km. Among them, nitrogen and oxygen are dominant, and there is almost no ozone. At an altitude of 60-90 km, there is an ionosphere called the D layer, which appears only during the day.

The temperature drops rapidly with altitude, dropping below -83 degrees Celsius at the top. The reason for this is that there is almost no ozone in this sphere, and most of the shorter wavelength solar radiation absorbed by gases such as nitrogen and oxygen is absorbed by the upper atmosphere.

Moreover, the vertical convective motion of the middle layer is strong.

Top 50 programming languages in the world:

Their main job is to make software for the company, write some programs, which is what we call IT people.

It's the same as the migrant workers on the construction site, and it can't be done if you leave, and the salary will not be too high, and you can recruit a young and strong person with a few ks of food and accommodation.

In general, the database has three layers, namely, the trembling beam: the presentation layer, the middle layer, and the data layer;

The role of the middle layer (webserver) is the logical bridge between user services and data services. It is responsible for accepting remote or local user requests, verifying user identities and access to data stocks, using server scripts, and using middleware.

The request is sent to the database server (i.e., the data carrier transport layer), and the data returned by the database server is logically processed and converted into HTML and various scripts and sent back to the client.

There are many things to learn, and you have to be proficient in the basic courses of college.

All other graphics artificial intelligence needs to be understood.

Otherwise, you can only do it.

If you don't have a foundation, it's hard to learn on your own, and it's good to have a Red Rabbit Game Academy in Beijing. According to the situation of the students, the teaching plan is formulated individually, and well-known Korean teachers teach to ensure employment.

Requirements are divided into two types: memorization requirements and software requirements, and user requirements are simply to record what users need software to do, and write more business terms. Software requirements are for programmers to see, on the basis of user requirements for processing, refinement, description of what functions the software to achieve, writing using more professional terms of software design.

If you want to write requirements, do not require the document format, only indicate the function to be implemented by the software, and if you want to write a special request format, you can fill in the format according to the requirements on the Internet.

Just write your needs clearly.
