electron bunch

基本解释

Measurement of electron bunch length through its generated CTR is a new frequency domain technique developed in the accelerator and FEL fields recently.
利用相干渡越辐射（CTR）测量短和超短电子束团长度是国际上束测领域新发展的频域测量技术。
In this paper, the electron movement is studied under the action of the microwave field in the cavity, and electron capture and bunch are also explored.
从微波场对电子运动的影响，研究了电子束在微波腔中的俘获、群聚和换能的束波互作用过程。
For measurement of the length of the electron bunch produced by the existing micro-pulse gun (MPG) device in NSRL, the design and construction work for the measurement system has been done.
以现有微脉冲束流电子枪（MPG）装置产生的电子束团为测量对象，开展了散能测量系统的设计工作。

We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.
然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。

And the reason that they're the least sheilded is because they can get closest to the nucleus, so we can think of them as not getting blocked by a bunch of other electron, because there's some probability that they can actually work their way all the way in to the nucleus.
它们最不容易被屏蔽的原因,是因为他们可以更加接近原子，所以我们可以认为它们,最不容易被其它原子阻挡住，因为它们有一定的概率,离原子核非常近。

So, this allows us to look at a bunch of different atoms, of course, limited to the fact that it has to be a 1 electron atom.
所以这让我们可以研究很多原子，只要它们都只有一个电子。
