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。

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。
