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(cè)量短和超短電子束團(tuán)長(zhǎng)度是國(guó)際上束測(cè)領(lǐng)域新發(fā)展的頻域測(cè)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(chǎng)對(duì)電子運(yùn)動(dòng)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(cè)量對(duì)象，開展了散能測(cè)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?cè)匍_始講元素周期表，我們會(huì)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。
