中子数 meaning in Chinese
neutron number
neutron population
Examples
- Although all nuclei of a given element contain the same number of protons, they may have different numbers of neutrons .
虽然,给定元素的所有原子核都含有相同数目的质子,但它们的中子数可以不同。 - The results of numeral simulation show that the higher - energy neutrons counting rate is quite low , it requires more counting time or much stronger low energy neutron source to detect the reliable signals
计算结果表明,核弹头裂变产生的较高能的中子数很少,需要较长的时间或较强的低能中子源才能探测到可靠的信号。 - If using the natural uranium to replace the heu pit in warhead , the delayed neutron counting rate would be about 3 times lower . the coincidence neutron detection is proposed to be used in nuclear warhead detection
计算表明用天然铀替代高浓铀作的假弹头,它们的出壳缓发中子数相差约3倍,需在一定条件下,才可对真伪核弹头做出判断。 - For the past 40 years , theorists have speculated that there should be an “ island of stability ” that would grant heavy elements a relatively long life if they had precisely the right number of protons and neutrons
在过去的40年中,理论家们推断有一个“稳定岛屿”结构可以保证重元素长期存在,如果它们含有精确且正确的质子和中子数的话。 - Arrays , whether local or class - level , are always initialized . ( 24 ) strings are initialized to null , not empty string . ( 25 ) an empty string is not the same as a null string . ( 26 ) a declaration cannot be labelled
这句话是说:多维数组中子数组不一定必须有一定个数的元素,比如我们把一个二维数组看成一个矩阵,那么行与列中的元素可以不完整,可以不对齐
