中子数

Properties of the 1 / 2 [ 660 ] (π i13 / 2 ) band in odd - A Au nuclei are discussed with an emphasis on the evolution of deformation while changing the neutron number .

这表示你可以改变中子数，而不会改变它的化学特性，因为化学特性是由质子决定的。

This means you can vary the neutron number without changing chemical identity , because chemical identity is fixed by the proton .

有相同的Z，相同的质子数，但是不同的A，也就是中子数不同。

They all have the same Z , the same proton number , but different A , which means number of neutrons varies .

利用密度相关零程对力的相对论连续谱hartreebogoliubov方法，对偶中子数的ca同位素从质子滴线到中子滴线范围内的单∧超核和双∧超核基态性质进行了系统研究。

Ground state systemic properties of single Λ and double Λ hypernuclei for even N Ca isotopes ranging from the proton drip line to the neutron drip line are studied by using the relativistic continuum Hartree Bogoliubov theory with a density dependent δ pairing interaction .

它是质子数加上中子数。

This is sum of protons plus neutrons .

中子数密度扩散系数

所以，我们可以间接得到中子数，因为我们知道质子数了。

So we get at the number of neutrons indirectly because we know the proton number here .

讨论了在一个增殖系统引发一个持续裂变链所需要的平均中子数。

The average neutron population necessary for sponsoring a persistent fission chain in a multiplying system , is discussed .

现在，看看中子数，我们要做的，是看到这左上方。

Now , to get to the number of neutrons , what we do is go up here to the upper left .

前言：通过原子核内中子数与质子数的差值&中质差，探讨构建“元素立体周期律”的可能性。

Using the difference between neutron and proton number in atomic nucleus , the " Element 's Periodic Law of Threedimensional ( solid )" is constructed preliminarily .

同位素：一种化学元素的两个或多个类型，它们的原子核具有相同的质子数，而中子数却不同。

Isotope : One of two or more species of atoms of a chemical element having nuclei with the same number of protons But different numbers of neutrons .

按照本文所提出的物理模型，只要计算的中子数足够多，其计算结果可完全在实验误差范围之内。

Adopting the physics mode given in this thesis , the accuracy of computed results is within experimental errors if the number of computed neutron is large enough .

氢壳层内部氢和重元素及氦壳层内的中子数和重元素的丰度偏低，而氦元素丰度偏高；

The abundance of H and heavy element in H-burning shell and neutron density and heavy element in He-burning shell are all reduced , but the abundance of the He is increased ;

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。

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 .

对国际象棋这样复杂的比赛而言，这种应对方式有其道理。据统计，在仅仅走过三步之后，每位选手就面临900万种可能的棋局。国际象棋中的可能棋局数，超过了宇宙中的中子数。

Such an approach is logical in a game so complex that players arrive at one of 9m possible positions after just three moves each - and one in which there are more possible unique chess games than neutrons in the physical universe .

本论文是课题研究成果的结晶，而根据侧重点的不同，大体可以分成四大部分。第一部分，OFDM系统中子载波个数与循环前缀大小的选择。

The paper is fruit of subject research achievement , and according to the emphases , It is be divided into four parts generally . First , we discuss about the OFDM system subcarrier number and cycle prefix .

相对于其他参数组，GL97给出的介子场强度最弱，中子星的相对数密度最大，物态方程也最软，同时采用GL97参数组计算的中子星的最大质量也最小。

现在，最后一件事是，因为中子没有净电子，我们可以改变中子数。

Now the last thing is that because the neutron has no net charge , we can change neutron number .

中子流动的速度；单位时间内穿越单位面积中子数。

The rate of flow of neutrons ; the number of neutrons passing through a unit area in unit time .

如果那是大于1，也就是说我们创造了，更多的中子，在一代里，相对于下一个，中子数增长，裂变速率也一样。

If it 's greater than one , namely we produce more neutrons in one generation compared to the next the neutron population grows as does the fission rate .

我们已经使用了一个相对简单的词语，称为，中子的增殖系数，那就是K，如果K等于1，中子数，是稳定的，裂变速率也一样。

And we 've used a relatively simplistic term called Neutron Multiplication Factor which is the K that if the K equals one the neutron population is steady as is the fission rate .

难以捉摸的量子力学表明，中子“太多”和“太少”有时会重叠出现，因而一些特定的元素没有稳定的同位素（或称变体，核内中子数不同）。

And the vagaries of quantum physics mean that " too many " and " too few " sometimes overlap , and there is thus no stable isotope ( or variant , with fewer or more neutrons ) of a particular element .
