Who is older Li Bai or Du Mu? Are Li Bai and Du Mu good friends?

1, Li Bai. Eleven years older than Du Fu.

2. Li Bai was born in 701 and was a great romantic poet of the Tang Dynasty and was praised as a poet by later generations.

and Du Fu are called Li Du, in order to distinguish from the other two poets Li Shangyin and Du Mu, that is, Xiao Li Du, Du Fu and Li Bai are also called Da Li Du.

3. Du Fu was born in 712 and was a great realist poet of the Tang Dynasty, known as Li Du together with Li Bai. Originally from Xiangyang, Hubei, he later migrated to Gongxian County, Henan.

and Du Mu are called "Little Li Du", Li Shangyin is called "Three Li" with Li He and Li Bai, and Wen Tingyun is called "Wen Li". 4, Du Mu (803 c. 852), the word Muzhi, the number Fan Chuan Jushi, Han nationality, Jingzhao Wannian (now Xi'an, Shaanxi) people. Du Mu was an outstanding poet and essayist in the Tang Dynasty, the grandson of Prime Minister Du You, and the son of Du Congyu.

Extended Materials.

Li Bai (701-762).

Du Mu (803, c. 852).

The two of them are not of the same generation.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.

There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.

When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.

Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.

In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.

The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.

In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.

The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

I think Li Bai and Du Fu should be good friends, after all, they are fellow travelers and can talk about everything.

Li Bai and Du Fu are called "Li Du".

1. Du Fu: The great realist poet of the Tang Dynasty, together with Li Bai, he is called "Li Du". Born in Gong County, Henan Province, he is originally from Xiangyang, Hubei.

In order to distinguish it from the other two poets Li Shangyin and Du Mu, that is, "Little Li Du", Du Fu and Li Bai are also called "Big Li Du", and Du Fu is often called "Old Du".

The core of Du Fu's thought is the idea of benevolence, and he has the grand ambition of "to the monarch and Yao, and then to make the customs pure". Although Du Fu was not famous during his lifetime, he later became famous and had a profound impact on both Chinese and Japanese literature. A total of about 1,500 poems by Du Fu have been preserved, most of which are collected in the "Du Gongbu Collection".

2, Li Bai: Qinglian Jushi, is a great romantic poet of the Tang Dynasty, and is known as a "poet immortal" by later generations. Li Zhimin, a professor at Peking University, commented:

Li Baizhi's poems breathe the universe and are out of the way; Du Fu's poems are towering from Confucianism, and they are all in the realm of the unity of heaven and man, so they can be superb. "The Book of the Old Tang Dynasty records that Li Bai is a native of Shandong; According to the Book of the New Tang Dynasty, Li Bai was the ninth grandson of the Xingsheng Emperor Li Wei, and was the same ancestor as the kings of Li and Tang. He is hearty and generous, loves to drink and write poetry, and likes to make friends.

Li Bai has "Li Taibai Collection" handed down, most of the poems are written when drunk, and the representative works include "Wanglu Mountain Waterfall", "Difficult to Travel", "Shu Road Difficult", "Will Enter the Wine", "Mingtang Fu", "Early White Emperor City" and many other poems. Li Bai's lyrics have been bigraphed by the Song people (such as Wen Ying's "Xiangshan Yelu" volume), and in terms of its pioneering significance and artistic achievements, "Li Baici" enjoys a very high status.

Summary. Li Bai was born in the first year of Chang'an, and Du Mu was born in 803 AD, so Li Bai grew up in Du Mu. Li Bai was born 102 years before Du Mu, an outstanding poet and essayist in the Tang Dynasty, and Li Shangyin is also called.

Li Bai was born in the first year of Chang'an, and Du Mu was born in 803 AD, so Li Bai was born in Du Mu. Li Bai Ruqing was born 102 years before Du Mu, an outstanding poet and essayist in the Tang Dynasty, and Li Shangyin is also called.

Li Baiqi is hearty and generous, loves to drink and write poetry, and likes to make friends. Li Bai is deeply influenced by Huang Lao Liezhuang's thoughts, there are "Li Taibai Collection" handed down, most of the poems are written when drunk, and the representative works are "Wanglu Mountain Waterfall", "Difficult to Travel", "Shu Road Difficult", "Will Enter the Wine Guess Touch", "Liang Fuyin", "Early White Emperor City" and many other poems.

Du Mu, the word Muzhi, the number Fan Chuan Jushi spine, Jingzhao Wannian, the poet and essayist of the Tang Dynasty Jie Zhao pants, and Li Shangyin are called "Little Li Du". His representative works include: "Bo Qinhuai", "Jiangnan Spring", "Red Cliff", "Wujiang Pavilion" and so on.

A Fang Gong Fu is the most pure name.
