electron bunch

基本解釋

Measurement of electron bunch length through its generated CTR is a new frequency domain technique developed in the accelerator and FEL fields recently.
利用相乾渡越輻射（CTR）測量短和超短電子束團(tuán)長度是國際上束測領(lǐng)域新發(fā)展的頻域測量技術(shù)。
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.
從微波場對電子運(yùn)動的影響，研究了電子束在微波腔中的俘獲、群聚和換能的束波互作用過程。
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.
以現(xiàn)有微脈沖束流電子槍（MPG）裝置産生的電子束團(tuán)爲(wèi)測量對象，開展了散能測量系統(tǒng)的設(shè)計(jì)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.
然後我們再開始講元素周期表，我們會看到很多周期性槼律，比如電離能，電子親和能，電負(fù)性以及原子半逕。

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.
它們最不容易被屏蔽的原因,是因爲(wèi)他們可以更加接近原子，所以我們可以認(rèn)爲(wèi)它們,最不容易被其它原子阻擋住，因爲(wèi)它們有一定的概率,離原子核非常近。

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.
所以這讓我們可以研究很多原子，衹要它們都衹有一個(gè)電子。
