In the past, we only had a few jobs to teach, but now we don t have anything, and we can still write

In the past, when we taught, it was only a few centimeters, but now that we don't have it, of course, it is a peaceful society, because teaching is the same as doing other things. As long as you like it, it doesn't matter if the centimeter is important, but due to the development of society, the work salary is getting higher and higher.

In the past, when I was teaching, people in the countryside worked for a share of the work, and there was also a subsidy of a few yuan. It is called a private teacher, most of them have become regular or have done other jobs, some are older, it doesn't matter, and they have not become state-run teachers until now. However, in recent years, there has been a bit of a subsidy, and according to the number of years of teaching, it is not much money.

If you don't have it there, you can go to the relevant department to complain about the problem.

In the past, it was not possible to make a good comparison with the present, but due to the progress of science and technology, the more and more disciplines are divided, the more carefully they are divided, so you will have different evaluations of this centimeter.

In the past, teaching was just to earn a part, and there was very little effort. It's also cheap to exchange for money and food, and now it's wages. Therefore, as you pay, the company also changes, which should be the benefit of the development of a peaceful society.

In fact, this current society is still a peaceful society, but everything is fair, and people will always encounter unfair things when they live in the world.

Of course, in a peaceful society, how high is the salary of teachers now.

Although there were only a few jobs in teaching before, now it is different from before, the more you earn, the more you do, the more you earn, which is also considered fair.

Due to the progress of the times, teaching has also begun to enter a completely competitive mode, and in addition, there are some things that do not mean that more is better. For the quality of teachers, it will be more and more demanding.

This society is like this, it is impossible to live completely in the ideal, because the people in reality are all material, so you can't imagine it out of thin air, and imagine those who are too radiant out of thin air.

In order for society to progress and develop, it is necessary to distribute the fruits of labor according to manpower.

Now the salary of teachers is still okay, they have a certain livelihood, the security is much higher than the previous living standard, and the treatment has also been improved.

The few people I live in put it.,Now there's nothing left.,It's still a death from illness.,Is it written for this? This is not necessarily, it is okay to gather with distance, and to speak.

You can't think like that, in the past, it was normal to earn centimeters, but now is not that era.

Rural teachers should be paid, don't you have one, and now where do you get to work, it's all paid in money.

The division of work, that era was too early. Now it's all about giving money directly, more directly.

We only have a few jobs to teach, and we have nothing until now, so is it still a peaceful society? It is impossible for you to teach nothing now, as long as you put in the labor, you should be paid.

In the past, you only had a few jobs in your family letters, but now you don't have anything, and to a certain extent, this should be a new system of checks and balances in a peaceful society.

In the past, we only taught 5 centimeters, but now we have everything or nothing at all, probably because the development of society is different.

In the past, our Savior only had a few companies, and now there are no companies at all, what is it like?

I read, this is written by Gorky.

In the dimly lit house, my father lay on the floor with his hands and feet spread.

He was dressed in white, barefoot, and his fingers were weakly bent.

The second chapter can be divided into three parts, that is, three beautiful and wonderful essays. They can be titled separately: "Brother Brawl", "Maternal Grandfather of **", "Maternal Grandfather Came to See Me in the Hospital Bed".

The central character of this chapter is his maternal grandfather. **Writing about the grandfather beating his grandchildren** is horrible, creepy. Later, he came to the hospital bed to see the scene of "me", and people felt that this old man's life experience was worthy of sympathy, and his shrewdness was admirable, although his ** could not be forgiven, but it was somewhat understandable, especially after reading the fifth chapter when he taught Alyosha "I" to read and talk about the philosophy of life during his illness.

Which part do you not understand?

In fact, the meaning of the title is very clear, the reaction principle and equation in front of it are equivalent to the background, and the second is just the problem.

NO can be gradually oxidized by O3 to N2O5 [note that SO2 does not react with O3], and then N2O5 and SO2 are reacted with NH3 together to form NH4NO3 and (NH4)2SO4 - that's what it means! In the end, as long as you understand the quantitative relationship between reactants and products, you can forget it.

5nox + 25-10x)/2]o3 = xn2o5 + 3(25-10x)/4]o2

so2＋o3＋2nh3＋h2o → nh4)2so4＋o2

v (ozone air) v (flue gas) flow ratio of y" means to tell you the volume ratio of ozone air to flue gas.

The volume ratios of NOx and SO2 in flue gas are calculated from the content of these two gases and ozone, respectively.

Based on the above two equations, it is obtained:

v(nox) :v(o3) = 1 : 5 - 2x ) / 2]

v(so2) :v(o3) = 1 : 1

And then from the title:

v(nox) :v(so2) = 1 : 2

Result: v(nox) :v(o3) = 3 : 5 - 2x) 2 + 2] = 3 : 9 - 2x) 2].

Since V(O3): V(Ozone Air) = 90:1000; v(nox) :v(flue gas) = : 1000 ; v (ozone air) : v (flue gas) = y

Yield: v(nox) : v(o3) = 1 : 20y

So: 3 : 9 - 2x) 2] = 1 : 20y

Derives: x = - 60y

I don't know if the answer is right, but the idea is right.

Flue gas contains sulfur dioxide and nitrogen oxides, and x refers to the coefficient of oxygen in nitrogen oxides. If the ratio of no and no2 is 1:2, then x=(1*1+2*2) (1+2)=5 3.

The rest is the column equation. Let no:no2=n:

1. x=(n+2) (n+1) is obtained, and then the amount of ozone consumed is calculated by the equation and the conservation of nitrogen in the conservation of materials, and then the amount of ozone consumed is expressed by n, and then the sulfur element is conserved, and the amount of ozone absorbed by sulfur dioxide is found. The amount of ozone air is solved by the amount of ozone and the concentration of ozone air O3 v (ozone air), and the flow ratio of v (ozone air) v (flue gas) is y, which is actually the volume ratio of gas used per unit time, so it can be represented by x n brought in, and then it can be known that v (flue gas) = v (no+no2 + so2), y = the amount of ozone air v v (flue gas) so can obtain the equation y and x. I'm making it very clear, it's for the sake of the equations.

Thus finding out the relationship between y and x ...

The purpose of the problem is to convert nox to n2o5 and finally get no3 - and so4 2 -

There are two noxes, no, no2

will be converted to N2O5 and O2

O2 then becomes O3 through the generator

The flue gases, i.e. N2O5 and O2, also have a certain amount of NOx

From , it can be seen that O3, SO2 and the excess NH3 in will react to get SO4 2- so the amount of flue gas can determine the amount of NO3 - , and the amount of NO3- obtained can represent the reacted NH3. Subtracting the reacted NH3 from all NH3 is the amount of NH3 in , which can naturally be expressed as the amount of ozone air. If the problem gives the concentration of O3 and SO2, that is, you can find the medium NH3, indirectly get the medium NH3, and from the above NOX you can get the total N2O5, and then find the NH3, and then get the flue gas.

In this way, the relationship between yy and x can be obtained.

Touching the fish, Yanqiu words.

Kim Yuan asked.

--Preface: Taihe is five years old, went to the test and merged with the state, and met the goose catcher; "Today, I will get a goose and kill it. Those who escaped from the net screamed and could not go, but threw themselves to the ground and died.

Because of the bought, buried on the Fenshui, tired stone for knowledge, called Yanqiu. Most of the companions were poems, and there were also "Yanqiu Ci". There was no palace merchant in the past, and now it is revised.

Ask what is the world and love, and teach life and death to promise?

There are double flyers in the south and the north, and the old wings have been cold and hot several times.

Happy and fun, parting bitter, there are even more crazy children.

You should have a saying, thousands of miles of stratus clouds, thousands of mountains and twilight snow, who does the shadow go to?

Hengfen Road, lonely when the drums, the smoke is still flat.

The soul is a little more groaning, and the mountain ghosts are crying in the wind.

The sky is also jealous, and the warblers and swallows are all loess.

Through the ages, in order to stay for the people, he sang and drank wildly, and visited Yanqiu.

Touch the fish. Yanqiu word (gold. Yuan Hao asked).

Taihe went to the test and the state in the fifth year, and the road met the goose catcher, cloud: Today, a goose was killed, and one of the people who got off the net screamed sadly.

Able to go, but he threw himself into the ground and died because he bought it, buried on the Fenshui, tired of the stone for the knowledge, called Yanqiu, and did "Yanqiu Words".

Ask what is the situation in the world, and the direct teaching promises life and death?

There are double flyers in the south and the north, and the old wings have been cold and hot several times.

Happy fun, parting bitter, there are more crazy children in it, you should have words.

Stratus clouds, thousands of mountains and twilight snow, to whom does the shadow go?

Hengfen Road, lonely when the drums, the smoke is still flat.

The soul is a little more groaning, and the mountain ghosts are crying in the wind.

Heaven and earth are jealous, unbelievable, warblers and swallows are loess, eternal and eternal.

In order to stay in the sau, he sang and drank wildly, and visited Yanqiu.

I have to say that "Infernal Affairs" is really a pretty classic movie, but after so many years, many actors have really changed a lot, and they really miss the appearance of Brother Guanxi back then!

Let's talk about our starring Andy Lau first! The Four Heavenly Kings, although they are now old and have fewer commercial performances, Andy's popularity really doesn't matter! All kinds of donations to contribute to China's charity!

And after debuting for so many years, there are really few scandals about him! I really miss the young Andy!

Let's talk about the person everyone pays the most attention to, Edison Chen! The little fresh meat that was popular in the entertainment industry back then! And he is willing to choose to quit the entertainment industry when he is at his most beautiful, and has the courage to admit his mistakes, this alone, I believe that many of the current little fresh meat can't do it!

Such a free and easy! Up to now, Edison Chen has his own fashion brand business, and there are shoes co-branded with AJ, Converse and major famous brands, which can be said to be the leader of China's fashion brand business! Now he also has his own family, get rid of the young and frivolous self before, and become a responsible person!

Infernal Affairs Niu Niu's face reached its peak state at that time,This TV is very good,Very good,It's very good,That's it。

The acting skills of the four major actors have reached their peak in this film, which can be called perfect, and many psychological activities are accurately expressed through their eyes, which is incisive. Especially Tony Leung's eyes, many people fell in love with him, and Tony Leung won the Hong Kong Film Awards for Best Actor again for his outstanding performance in the film. This film won the Best Film at the 22nd Hong Kong Film Awards, which can be called a classic of Hong Kong films and a classic of police and gangster films.

The reason for the demise of the Three Kingdoms.

At the end of the Eastern Han Dynasty, the world was in turmoil, coupled with the heavy blow of the Yellow Turban Uprising, the Eastern Han regime existed in name only. In the process of suppressing the Yellow Turban Uprising, the princes of all parties also became more and more powerful, forming a situation of division and strife. Among the princes at that time, Cao Cao and Yuan Shao were the most powerful.

Cao Cao adopted the advice of Yuan Shao's advisor Xu You, defeated Yuan Shao, unified the north, and "coerced the princes of the Son of Heaven", laying the foundation for the later strength of Wei. But the demise of Wei also stemmed from Cao Cao: Cao Cao could not value the people.

Mencius said, "The people are precious, the community is secondary, and the monarch is light." And Cao Cao not only thinks that the monarch and the people are light, but also thinks that "he is noble and the people are light", which can be seen from his sentence "I would rather let the people of the world bear me, and Hugh let the people of the world bear me". Cao Cao was jealous of the virtuous and jealous, and valued martial arts over literature.

He admired generals like Guan Yu and Zhao Yun very much, but he killed Xu Yu and beheaded Yang Xiu, so that Wei had no one to make plans, so that when the Shu army attacked, he had to use careerists like Sima Yi and Sima Zhao. Sima's father and son grew in power in the process of destroying Shu, and finally destroyed the Wei state.

In the process of Cao Cao's unification of the north, Liu Bei, one of the northern princes, fled in a hurry. Liu Bei looked at the thatched cottage three times and invited Mr. Wolong-Zhuge Liang to help, this person blocked Cao's army with the fire of Bowang and the water of the White River, and lobbied the Eastern Wu army to resist Cao, so that Cao Cao's army was defeated in Chibi. From then on, Cao Cao retreated to the north, Liu Bei took Xichuan directly, and Sun Quan dominated Eastern Wu.

Zhuge Liang not only made outstanding contributions to the Shu regime, but also promoted the formation of the Three Kingdoms.

The prosperity of Shu was made by Zhuge Liang and destroyed by Zhuge Liang. After the death of Emperor Zhaolie Liu Bei, Liu Chan, the queen of Shu, was incompetent. According to Liu Bei's will, Zhuge Liang could have established himself as the emperor, but not only did he fail to do so, but he also failed to persuade Liu Chan in a timely and effective manner.

The Battle of Jieting lost an important grain route - Jieting due to improper employment of personnel. In the end, he passed on his life's experience of fighting to Jiang Wei, although Jiang Wei had the ambition to help the Han family and the ability to lead the troops to fight, but in the end because the Shu lord Liu Chan was incompetent and could not reuse him and was destroyed by the Wei army.

Sun Ce was located in Jiangdong, and after Sun Ce's death, Sun Quan ascended the throne. The first battle of Chibi made Cao Cao's dream of destroying Eastern Wu come to naught, so Sun Quan made great contributions to the stability of the Eastern Wu regime. But Sun Quan was also the source of the demise of Eastern Wu:

After the Battle of Chibi, Sun Quan disregarded the current plan to resist Cao, forcibly seized Jingzhou, and killed Guan Yu, causing Liu Bei to be annoyed and ashamed, raising troops to attack Wu, and the Wu-Shu alliance broke down, causing great damage to the vitality of the two countries, giving Wei an opportunity; The alliance between Wu and Wei to attack Shu was not successful, but it put Eastern Wu in a dilemma of whether to join Wei and attack Shu or join Shu to attack Wei.

To sum up, it is not difficult for us to see the reasons for the demise of Wei, Shu, and Wu, and they all have one thing in common: they have made great contributions to the prosperity of the country, and at the same time, they are also the source of the country's decline. For this we can say:

The rise and fall of the three kingdoms of Wei, Shu, and Wu was decided by Cao Cao, Zhuge Liang, and Sun Quan! ”
