查询词典 ionisation

The exact effective nuclear charge numbers have been defined andcalculated with the mean radius of the initial orbital of the active electron toconsider the combined -effects of relativity and screening in an actualtranstition calculation . The electron impact ionisation cross sections and thecorresponding ionisation rate coefficients of Li like ions 〓、〓、〓、〓and〓 have been calculated by using our calculated effective nuclearcharge numbers.

我们考虑并修正了原始理论中对屏蔽常数物理意义的不正确定义和算法，更精确考虑了其它电子对被电离电子的屏蔽效应以及相对论收缩对有效核电荷数的影响，得到了更可靠的有效核电荷数，并给出了更好的电离截面结果。

As they form the level of ionisation gradually builds up, affecting first the lower frequencies, and later higher frequencies as the level of ionisation increases.

当他们形成电离的水平逐渐加强，首先影响更低的频率，和最新更高的频率作为电离增量的水平。

As they form the level of ionisation gradually builds up, affecting first the lower frequencies, and later higher frequencies as the level of ionisation increases.

当它们的电离度开始逐渐增强时，首先影响较低的频率，而更高频率通常显示出电离度的增加。

In particular the atmospheric pressure chemical ionisation and the electrospray ionisation methods are nowwidely used in routine analysis (see also section on PTR-MS and HOx radicals below).

尤其大气压化学电离和电喷雾电离方法现在广泛应用于常规分析（请参见PTR 和 HOx 下有关基础）。

The detector housing is identical to that of the ionisation smoke detector.

该探测器的房屋是相同的探测器的电离烟雾。

In 1902 Lenard showed that an electron must have a certain minimum energy before it could produce ionisation when it passed through a gas.

莱纳德在1902年提出，当电子通过一种气体时，必须具有一个确定的最小能量，才能产生气体的电离。

It is found that the sporadic E ionisation clouds move.

它被发现分散E 电离云彩行动。

The aurora is associated with increased ionisation in the E layer and it is from this that the signals can be reflected.

极光同增加的电离联系在一起在E 层数并且是从这信号可能被反射。

VHF can also be reflected from clouds of increased ionisation in the E layer of the ionosphere.
