原子核分裂 meaning in English
atomic disintegration
atomic fission
nuclear fission
Examples
- In this process the nucleus breaks up into two intermediate-sized nuclei .
在这种过程中，那个原子核分裂成两个中等大小的核。 - Material which is capable of producing energy by a self - sustaining chain reaction of nuclear fission
一能由原子核分裂之自续连锁反应而产生能量之物料。 - In addition to splitting the nucleus into two halves , the process releases two or more neutrons and a large amount of energy in the form of heat . the released neutrons in turn hit more uranium nuclei and release more neutrons to produce a chain reaction
核裂变过程除了把原子核分裂成两份外，亦会释放大量的热能及同时放出两个或以上中子，以撞击更多铀原子核，再释放更多中子，产生链式裂变反应。 - In addition to splitting the nucleus into two halves , the process releases two or more neutrons and a large amount of energy in the form of heat . the released neutrons in turn hit more uranium nuclei and release more neutrons to produce a chain reaction
核裂变过程除了把原子核分裂成两份外，亦会释放大量的热能及同时放出两个或以上中子，以撞击更多铀原子核，再释放更多中子，产生链式裂变反应。 - After the star enters the main sequence stage , energy comes from nuclear fusion , the combination of several small nuclei into a large nucleus . in contrast , the nuclear plants on earth generate energy by nuclear fission , the splitting of a large nucleus to several smaller ones
只要星体进入主序星阶段，能量转为来自核聚变相反地地球上的核电厂使用的是核裂变，即大原子核分裂为众多小原子核，过程中释放能量的机制。
