The internal structure of the Sun is divided into photosphere, chromosphere, and corona.
According to the relative intensity of solar activity, the sun can be divided into two categories: the quiet sun and the active sun. The Tranquility Sun is a theoretically assumed spherically symmetrical hot gas sphere whose properties vary only with radius and are uniform in either sphere, with the aim of studying the general structure and general properties of the Sun.
Under this assumption, the Sun is composed of a core, a radiation region, a troposphere, a photosphere, a chromosphere, and a corona, in order from the inside out. Below the photosphere is called the interior of the Sun; Above the photosphere is called the solar atmosphere.
The evolution of the sun.
The Sun was formed about 100 million years ago in a cloud of collapsed hydrogen molecules. The time of the Sun's formation is measured in two ways: the Sun's current age in the main sequence zone, confirmed using computer models of stellar evolution and primordial nucleosynthesis, which is about 100 million years old.
This is very consistent with the radioactive dating of the oldest material of the sun is 100 million years old.
The Sun has reached middle age in the evolutionary phase of its main sequence, in which nuclear fusion is the fusion of hydrogen into helium at the core. More than 4 million tons of matter are converted into energy in the Sun's core every second, producing neutrinos and solar radiation. At this rate, the Sun has so far converted about 100 Earth-masses of matter into energy.

The structure of the Sun is divided into two parts: the solid sphere and the atmosphere.
The atmosphere from the outside to the inside is the corona (1 million), the chromosphere hail (4500) and the photosphere (6000). From the outside to the inside, the solid sphere is the troposphere, the radiation region, and the solar nucleus (hydrogen-helium nuclear reaction zone, with a temperature of up to 15 million). The solid sphere is divided into boiling and liquid magma boiling layers, liquid and solid substances, and iron-nickel solid solar cores.
The solar system is a big vortex, like the Milky Way. The vortex force in the vortex brings the hydrogen cyclones together to form a hydrogen disk. The hydrogen in the sun is very dense, and it rubs against each other to generate heat under the spiral force of vortex force, and the temperature rises to 10 million and then fuses into helium atoms, and the heat generated is transferred to the surface of the sun through radiation, convection, and conduction to form a photosphere and a chromosphere.
As the sun gradually rounds, the internal temperature rises, and the helium atoms coalesce into lithium atoms. In the same way, it continues to fuse into various atoms.
The size of the sun as well as its composition
The collapse of the solar structure caused by the reconnection of magnetic field lines on the surface of the sun leads to the formation of coronal eruptions, magnetic clouds, solar flashes and shock waves. Helioseismology was developed by studying the transmission of this seismic wave, and the inner part of the sun from the inside to the outside was explored as the core layer, radiation layer, troposphere, photosphere, chromosphere, and coronal region.
The large sphere of the Sun is 864,000 miles in diameter and contains 3,350 billion cubic miles of extremely hot gas, weighing more than twice as many as 10 to the 27th power. The density, temperature, and composition of the various gases hidden deep in the sun's interior have been speculated, allowing astrophysicists to figure out the nuclear reactions that cause these gases to burn, as well as the age of the sun's formation.

The internal structure of the sun can be divided into three parts: the core, the radiation layer and the troposphere, and the atmospheric structure can be divided into three layers from the inside to the outside: the photosphere, the chromosphere and the corona.
The solar atmosphere is the outer layer of the sun, which is the photosphere, chromosphere and corona from the inside out. The temperature of the solar atmosphere is about 4500 degrees Celsius at the edge of the chromosphere above the photosphere 500 km, and then increases rapidly with the altitude, and the temperature increases rapidly in the transition zone, and at the bottom boundary of the corona zone at an altitude of 10000 km, the temperature has reached more than 10 to the 6th degree Celsius.

The structure of the sun is a monolithic structure.
The single character is a Chinese character composed of strokes as the direct unit of the staring wheel, and it is a whole that cannot be separated.
The hieroglyphs and ideograms of the individual characters are the basis for the formation of the combined characters.
The pronunciation of the word "sun" is tài. The original meaning is big and big. Such as:
Zizhi Tongjian": The king takes the eldest son as the prince, and is called the deputy prince of the country, Kong Yingtong Jian Da said:'Tai, Dazhong Kaiju is also great, "Shangshu Yugong":
Both repaired Taiyuan, as for Yueyang, "I Ching: Dictionaries": Therefore, it is easy to have Taiji, and it is to give birth to two instruments.
Another example: Taixue, Taixuan, Taixi, Taihu, Sun.
The types of kanji structures are:
The shape structure of Chinese characters can be divided into four levels: Chinese characters, parts, strokes, and pen shapes. Chinese characters are the highest level, parts are the middle level, strokes are the second lowest level, and pen shapes are the lowest level.
There are eight structures:
1. Single-character characters.
2. Upper and lower structure.
3. Upper, middle and lower structure.
4. Left and right structure.
5. Left-center-right structure.
6. Semi-enclosed structure.
7. A fully enclosed structure.
8. Zigzag structure. <>

The following is the body structure of the three-way control valve**, you can look at it, you can see from the figure that the three-way control valve has two valve seats, to give a column, the valve is now three-way confluence regulation, the left and the bottom are the inlet pipe, the left side of the cold water into the hot water, you need to adjust the temperature of the mixed water, this is the most typical case, the valve factory state is set to 4mA when the valve is left and right, the lower inlet is closed, so now adjust the mixing temperature to input 4-20mA signal, When 12mA, the left and the bottom are opened half, and the left side is fully closed when the 20mA signal is entered, and the bottom is fully open, so that the left and bottom sides can be adjusted to open the water, so as to control the temperature of the mixed water. (FYI).
