由第二段第一句“For the first time,researchers created a nuclear fusion reaction that produced more energy than they put into the process.(研究人员首次创造了一种产生的能量比他们投入的能量多的核聚变 反应。)”可知,核聚变反应的突破是其产生的能量比投入的要多。 故选D。 33. D。细节理解题。由第...
In fusion we get the energy when two atoms fused together to form one atoms. With current technology the reaction most readily feasible is between the nuclei of the deuterium (D) and tritium (T). Each D-T releases 17.6 MeV of energy. The use of nuclear fusion plant will substantially ...
"First, you start a flame, heat the wood and at some point a chemical reaction starts, and then this reaction is enough to burn the rest of the wood." Getting energy from nuclear fusion Atoms are composed of a nucleus (containing protons and neutrons) and electrons. Infusion, two atoms ...
Consider a fusion reaction in which two deuterium nuclei fuse to form a tritium nucleus and a proton. How much energy is released in this reaction?Nuclear reaction:A nuclear reaction is a reaction in which the nuclei of the ...
The future of nuclear energy Research into nuclear energy is ongoing, especially into nuclearfusion: nuclear energy can also be released in a reaction that combines two atoms to form a larger atom. However, this reaction is much less controllable than a fission reaction.23 ...

The experiment, at Lawrence Livermore National Laboratory,showed ignition: a fusion reaction generating more energy out than was put in. In addition, the past few years have been marked by amultibillion-dollar windfall of private investment in the field, principally in the United States. ...
Massive stars (greater than five times the mass of the Sun): When their hydrogen becomes depleted, high mass stars convert helium atoms into carbon and oxygen, followed by the fusion of carbon and oxygen into neon, sodium, magnesium, sulfur and silicon. Later reactions transform these elements...
Nuclear Fusion Process The star uses a process callednuclear fusion, which involves the merging ofhydrogen nucleito release energy. The star begins to generate energy when it reaches a temperature of 10 million Kelvin or 18 million degrees Fahrenheit. Nuclear fusion begins when hydrogen atoms, or ...
Fusion energy is the process that powers the sun and other stars, and experts have been trying for decades to master it on Earth. It is achieved when two atoms that usually repel are forced to fuse together. It’s the opposite of nuclear fission — the type widely used today — which ...
