1. N = mechanical efficiency
W = useful work
Q release itself means heat release, At this time, do the total work
m = mass
q = calorific value
P = power
W = work
t = time
F = tension
V = speed
s = distance
G = gravity
H = height
mechanical efficiency = active work / total work (heat released)
heat released = mass times calorific value
power = total work / time = tension times speed (this is derived from the previous formula) Total work = pull force times distance = gravity times height

2. State coercive force refers to the state violence reflected by the state through prison, court, army, police and other material forms, which is the institutional basis of the existence of legal authority

3. At present, the best way to improve desulfurization efficiency is to add efficiency catalyst! The advantages are as follows:
1. Desulfurization efficiency can be improved without adding or modifying desulfurization equipment
2, if the SO2 concentration is within the design value, the slurry circulating pumps of some absorption towers can be shut down, and the auxiliary power consumption can be reced accordingly; In addition, the utilization rate of coarse-grained limestone can be effectively improved to save energy consumption of ball mill in pulping system
3. When the concentration of SO2 exceeds the standard (generally less than 1.5 times), adding efficiency catalyst can ensure the desulfurization efficiency up to the standard. Because the price of high sulfur coal is much cheaper, it becomes the best choice for power plants to save energy and increase efficiency
4, the active components in the catalyst can improve the surface activity of limestone, increase the dispersion of limestone and rece its sedimentation rate, rece the scaling and blockage of operating equipment, thus recing equipment loss and maintenance costs
5, the catalyst can improve the solubility of limestone in liquid phase and strengthen the dissolution of limestone; At the solid-liquid interface, the catalyst can provide an acidic environment concive to the dissolution of CaCO3, rece the liquid resistance, promote the dissolution of limestone, improve the utilization rate and rece the dosage.

4. Yes, unless you prove that you really don't want to have a relationship, how can you prove it? Unless you're in the process of divorce, you're in a life and death relationship. Who can tell,

As for the performance of gt-25000 / qc-280 marine gas turbine, it can be seen from one point alone that only the United States, the United Kingdom, Ukraine and our four countries can independently proce marine gas turbine in the world. Even Russia can not proce marine gas turbine independently at present, that is to say, it is at least the top four countries in the world that can proce marine gas turbine{ RRRRR}

while the United States and the United Kingdom are even better at marine gas turbines. The mt30 marine gas turbine proced by the British RORO company has a power of 36 MW and a high level of miniaturization. Its box weight is only 26 tons, and its thermal efficiency has reached 42%. At present, the mt30 marine gas turbine with a capacity of 60000 tons is & quot; Queen Elizabeth & quot; The carrier is relying on two mt30 as the main force

in addition, the mt50 marine gas turbine newly developed by the British RORO company has more advanced performance, with a single total power of 50 MW, which is currently the largest marine gas turbine in the world

the technology of marine gas turbine in the United States is also quite advanced. Its lm-25000 gas turbine can be said to undertake the power plant of half of the destroyers in the world, and the most improved derivative models are also available. From the lm-2500 basic model of 18 MW to the lm-2500g4 model of 35 MW, there are almost all power requirements

in a word, although qc-280 marine gas turbine can be ranked among the top four in the world, there is still a lot of room for improvement in miniaturization, service life, thermal efficiency and power

6. The differences between violence and violence are as follows: different reference, different citation and different emphasis; Cruelty and ferocity< Violence: the force of coercion< Violent: Qin Mu's Yihai Shibei fresh litchi and dried litchi: "the vast majority of nervous patients are quite silent... Manic and violent, on the contrary, is a rare manifestation of neuropathy."
2. Violence: "there is a famous saying in Das Kapital:" violence is the midwife of every old society pregnant with a new society. "< 3. Different emphases
1. Violent: it focuses on one kind of character
2. Violence: focusing on a behavior.

7. The gas turbine used in large warships is a kind of high-end large-scale instrial equipment, which can only be manufactured in the United Kingdom, the United States, Ukraine and China; Among them, lm2500 gas turbine is the most advanced gas turbine in the world, and also the most exported gas turbine. It is the main power of all types of aegis ships in the United States. It is also installed on large destroyers around the world, such as Japan's King Kong, Atang class and South Korea's Shizong King class destroyers. Its advantages include miniaturization, thermal efficiency and power, In terms of service life, it is also ahead of the GT25000 imported from Ukraine in the 1990s and the domestic model qc280 marine gas turbine. During the honeymoon period between China and the United States, China also imported lm2500, but only a few of them were out of stock by the United States. There is no choice but to import Ukrainian gas turbines. As for the gap with lm2500, at least our warships don't have to worry about being stuck, otherwise they won't make mplings. This is the biggest significance of localization of Ukrainian GT25000 gas turbines! Fortunately, the most difficult pass has been passed, and there will be a broad road in the future. No one can stop China's progress!

1、 National compulsion of law means that law embodies state power and is guaranteed by state compulsion

if there is no state power and the guarantee of state coercive force, the law can not be universally observed, it will lose its significance of independent existence, and it will not become law. Whether it has national compulsion or not is an important sign of the difference between law and other social norms. Although other social norms also have certain compulsion, they are not national compulsion. For example, morality mainly depends on the compulsion of public opinion, and habits are forced by huge habitual forces. This kind of coercion is different from the state coercion

Second, national coercive force is backed by national coercive institutions (such as the army, police, courts, prisons, etc.), which is related to national sanctions, and is manifested as national coercive measures taken against offenders

Thirdly, the national compulsion of law is the inherent attribute of law itself, which is related to and different from the way of realization of law. It is because of the national compulsion of law that it is possible to guarantee the realization of law through national coercive measures when necessary. However, the realization of law is not always through national coercive measures. People obey the law out of various motives, not necessarily out of fear of legal sanctions

socialist law embodies the interests and wishes of the people. In most cases, it depends on the conscious compliance of the people. Only when there are obstacles in the process of the realization of the law can the state take compulsory measures

(1) the essence of law is the embodiment of the will of the ruling class

The content of law is determined by the material living conditions of the ruling class. Law is a social norm to regulate human behavior

Law is the social norm of the state, law is the social norm of rights and obligations, and law is the social norm guaranteed by the state's coercive force Secondly, human behavior is the adjustment object of law. It can also be said that the object of law is social relations. The meaning of the two statements is the same, because social relations are nothing more than the behavior interaction or interactive behavior between people. Without the interaction between people, there would be no social relationship. The law adjusts people's behavior, at the same time, it also adjusts social relations. The behavior as the adjustment object of law refers to people's external behavior

The law is made or approved by the state, so it must have the attribute of the will of the state, so it has a high degree of unity and universal applicability. This unity is based on the unity of state power and state will. The unity of law first refers to the consistency of the fundamental principles among the various laws, and then refers to that except for special circumstances, a country can only have a general legal system, and the norms within the legal system can not contradict each other

The universal applicability of law can be extended from the unity of law, that is, law as a whole has universal binding force within the scope of national sovereignty, and all state organs, social organizations and indivials must abide by the law. Everyone's legal behavior is protected by law without exception, and anyone's illegal behavior is punished by law without exception

3. Law is a social norm that stipulates rights and obligations.

law regulates people's rights and obligations, takes rights and obligations as a mechanism, influences people's behavior motivation, guides people's behavior, and adjusts social relations. Right means that people can do or not do certain acts and can ask others to do or not do certain acts. By stipulating rights, the law enables people to obtain certain benefits or freedom

Obligation means that people must do or not do certain behaviors. Obligations include the obligation to act and the obligation not to act. The former requires people to do certain acts, while the latter requires people not to do certain acts. It is precisely because the law regulates people's behavior by stipulating their rights and obligations that people's legal status is embodied in a series of legal rights and obligations

4. Law is a social norm guaranteed by the state. Any kind of social norm is mandatory and has social power to ensure its implementation. The difference between law's compulsion and other norms is that law has national compulsion< The law is backed by the national coercive force, which guarantees its implementation. The national compulsion of law is manifested not only in the negation and sanction of illegal acts by the state, but also in the affirmation and protection of legal acts by the state. It is manifested not only in the formal power of state organs according to law, but also in the fact that citizens can request the state to protect their legal rights according to law. Whether it has national coercive force is the decisive standard to judge whether a rule is law

it must be pointed out that the law relies on the national coercive force to ensure the implementation, which is in the ultimate sense, that is, from the sense that the national coercive force is the last line of defense of the law, rather than means that every implementation process of the law and the implementation of every legal norm should rely on the systematic violence of the state. It is not to say that the national coercive force is the only force to ensure the implementation of the law
