The first country to really use nuclear technology for peaceful causes was

The United States, in 1945, dropped one each on Hiroshima and Nagasaki in Japan.

Answer] :d In 1954, the Soviet Union built the world's first nuclear power plant in Qin Ho Hau, and it was the first to apply nuclear energy to the cause of peace. Therefore, the correct answer to the case is d.

Answer]: c Slippery silver analysis:

After China's first nuclear weapons test in 1964, it publicly announced to the world that it would not be the first to use nuclear weapons, that it would not explicitly justify the use of nuclear weapons against non-nuclear countries, that it would not proliferate nuclear weapons, and that countries with nuclear weapons in the world should completely and completely destroy nuclear weapons. China is an active promoter of nuclear disarmament and the only country in the world that has pledged not to be the first to use nuclear weapons.

Nuclear ** is the top technology in military technology, and it is extremely powerful.

It uses the huge energy released instantaneously from the nuclear fission or fusion reaction that can be carried out self-sustainingly to produce the best effect and has a large-scale destructive effect.

Nuclear** refers to the enormous lethality associated with nuclear reactions, including hydrogen bombs, atomic bombs, neutron bombs, three-phase bombs, antimatter bombs, etc.

The energy released during a typical chemical explosive, such as TNT**, comes from the decomposition reaction of the compound.

In these chemical reactions, the nuclei of atoms such as carbon, hydrogen, oxygen, and nitrogen do not change, but the combined state of the individual atoms changes.

Unlike chemical reactions, nuclear fission or fusion reactions involve the transformation of the nuclei of the atoms involved in the reaction into other nuclei, and the atoms change.

Therefore, it is customary to call this type of **atom**.

But in essence, it is the reaction and transformation of the atomic nucleus, so it is more accurate to call it a nucleus**.

Nuclear ** uses the huge energy released instantaneously by the fission or fusion reaction of atomic nuclei that can be carried out self-sustainingly to produce ** effect, and has a large-scale destructive effect. Nuclear is also called nucleons or atoms. Broadly speaking, nuclear ** refers to a nuclear** system with combat capability, including a throwing or launching system.

Nuclear ** usually refers to nuclear ** in a narrow sense, that is, a nuclear bomb composed of a nuclear warhead and a guidance, penetration and other devices loaded into the warhead shell. The main body of the nuclear warhead is a nuclear ** device, referred to as a nuclear device. The nuclear device, together with the detonation control system, etc., forms the nuclear warhead.

The nuclear warhead and guidance, penetration and other devices are loaded into the warhead shell, that is, the nuclear warhead of a ballistic missile is constituted. In a broad sense, nuclear weapons usually refer to nuclear systems with combat capability consisting of nuclear bombs, drop-launch systems, command and control, communications, and combat support systems.

High, precise and sharp, it belongs to the top technology.

Answer]: a, c, d

Answer]: a, c, dAnalysis: Nuclear power generation uses nuclear split skin wood energy. Item D should be distinguished from the knowledge point that "the United States is the country with the largest number of nuclear power plants in the world". Therefore, the answer to this question is ACD.

<> "Under what circumstances will our country use nuclear **?

The birth of nuclear ** scared the whole world, because its lethality was so great that a single atomic bomb could destroy a city and kill hundreds of thousands of people. It can be said that whoever has nuclear ** will be able to defeat a country that does not have nuclear **. Therefore, in order to counterbalance this extremely asymmetrical lethality, many countries have nuclear weapons, and China is no exception.

In the last century, the United States dropped two atomic bombs on the cities of Hiroshima and Nagasaki, causing hundreds of thousands of deaths and turning the cities into ashes. The tragedy of the scene is indescribable, and I believe it is not a scene that people want to see. Therefore, China has a principle, that is, the principle of never being the first to use nuclear weapons, and never using nuclear weapons or threatening to use nuclear weapons against non-nuclear countries.

Such a principle formulated by our country is very humane.

However, there is a rumor that China is preparing to formulate an amendment on the use of nuclear weapons, and a new principle on the use of nuclear weapons, and China will use the three principles of nuclear use, thus breaking the previous regulations. These three principles are: first, when China's nuclear ** or nuclear facilities are attacked by various conventional ** enemies.

Second, when China's aircraft carriers and strategic missile submarines are attacked by the enemy's nuclear or conventional. Third, China uses nuclear power when important facilities such as China's important water conservancy facilities are attacked by the enemy.

However, this news has not been confirmed by the state, but it is worth noting that this news comes at a time when China and Japan are at odds in the East and South China Seas. There is speculation that this is very likely to be a kind of tentative behavior of China, a kind of deterrent to those countries that frequently provoke China and clamor for armed attacks on China's aircraft carriers and strategic nuclear submarines.

In the face of a country that is quite unreasonable, we must not treat each other with courtesy. Therefore, China will not stick to one principle. In the face of the rapidly changing situation in the world, we should use it flexibly in order to truly safeguard national interests and safeguard the security of the motherland.

a.China, the United States, Russia, the United Kingdom, India.

b.China, the United States, Russia, the United Kingdom, France.

c.China, the United States, Russia, India, Pakistan.

d.China, the United States, Russia, South Korea, Israel.

Correct answer: China, the United States, Russia, the United Kingdom, France.

"Never be the first to use nuclear weapons" is the embodiment of China's foreign policy of peaceful development.

1. The power of nuclear ** will cause huge ***, so the use of nuclear ** is extremely cautious;

2. China adheres to peaceful development. Peaceful development refers to developing oneself through striving for a peaceful international environment and promoting world peace through one's own development.

3. Proposing no first use of nuclear **, not no use of nuclear **, this kind of policy is not only a manifestation of advocating peace, but also safeguarding national interests.

Never be the first to use nuclear **, the meaning of this is very deep, one is to show the world that we have nuclear **, not easy to bully. The second is to warn those who are eyeing our country not to act rashly, because we have the ability to defend national sovereignty. The third is that we are a more humane, just country that does not use nuclear weapons first.

Fourth, never say that you will never use nuclear **, hehe, you guys will try!

The commitment not to be the first to use nuclear ** is a great deterrent to other countries, indicating that China has the capability of a second nuclear strike, that is, it can still carry out a nuclear strike on the other side even after being carried out by the other side in a nuclear strike. There are only a handful of countries capable of a second strike. This is the main intention of our commitment not to test nuclear weapons first.

It's too naïve, the Chinese Chinese words are broad and profound, in fact, this sentence means: my country will use conventional ** to hit you first, and then immediately use nuclear ** to hit you. It cannot be understood as: if other countries use nuclear **, China will use nuclear **.

This sentence can also be understood in this way, China will not use nuclear ** first, it can use conventional ** and then use nuclear **.

It's for the poor buddies of the Third World. I have a primordial bomb but absolutely do not engage in nuclear blackmail, unlike the US imperialists who have been threatening to use nuclear weapons against China all the time, now that I have it, I have it too, and I am proud of it.

Also, no first use no = no use.

Anyway, the big powers won't use nuclear ** at all, so it's better to make a gesture and say that we won't use it first.

China is relatively backward, and the nuclear power is also very harmful, which is conducive to peace.
