3. The sun's energy comes from ___.A. nuclear fissionB. burning fuelsC. X-raysD. layers of yaze 相关知识点: 试题来源: 解析 A. nuclear fission 太阳的能量来自于核聚变反应,即氢原子核在太阳核心区域融合成氦原子核,释放出巨大的能量。核聚变与核裂变不同,核裂变是重原子核分裂,而核聚变是轻...
Nuclear Fission - ScienceDirectNuclear fusion, the energy source that fuels the Sun and stars, can potentially be exploited to generate electricity. The process in the Sun involves the fusion of hydrogen atoms at extremely high temperature and pressure. Those conditions cannot be recreated on the ...
Nuclear fission occurs when a heavy atomic nucleus splits into two, with the release of energy. Nuclei are made up of protons and neutrons, but the mass of a nucleus is always less than the sum of the individual masses of the protons and neutrons inside. The difference is a measure of ...
heavier than iron absorbs energy. The opposite is true for the reverse process, nuclear fission. This means that fusion generally occurs for lighter elements only, and likewise, that fission normally occurs only for heavier elements. There are extreme astrophysical 天体物理学 events that can lead ...
Nuclear fission is the splitting of the nucleus of an atom. Only a few elements are suitable for use in this way, the most important ones being Uranium-235, Uranium-233, and Plutonium-239. When a nucleus of one of these elements is struck by a free neutron it breaks down into two lig...
根据第三段内容Typically, 60-90% of the energy produced is lost, meaning that we can only use 10-40%.There is also the problem of waste materials and pollution.Nuclear fusion is more than ten million times more efficient (高效的) than burning coal as a source of energy.可知,通常,产生的...
But generating commercially viable energy fromnuclear fusionstill remains more science fiction than reality. Meanwhile, its more reliable sibling,nuclear fission, has been powering our world for many decades. 但是,从核聚变中产生商业上可行的能源仍然更像是科幻小说而不是现实。与此同时,它更可靠的兄弟,核...

The declining reserves of fossil fuels and their detrimental effects on the environment have thrust nuclear power based on fission reaction into the limelight as a promising option to energy-starved economies around the world. However, the 1986 Chernobyl
This process releases an enormous amount of energy, far greater than what is possible with fission, and produces no long-lived radioactive waste. In addition, the fuel for fusion, such as deuterium and tritium, is abundant and can be extracted from seawater, making it a virtually limitless ...
