查询词典 on the beam

Influence of the Kerr Effect on the Focusing Property of the Gaussian Beam［J］.

克尔效应对高斯光束聚焦特性的影响［J］。

So, our main work is to obtain a satisfactory electron beam with diameter about micrometers by means of choosing a suitable LaBe cathode electron-gun system and a suitable focusing system.

电子束打靶产生X射线已经是很成熟的理论，因此，本论文的理论研究重点是选择合适结构的电子源系统与合适结构的聚焦系统并将电子束会聚为微米级的细小束斑。

In the subsequent experiments, when the LaBe cathode emitted continuously and the current is 40uA, the minimum diameter of electron-beam spot recorded was 22 um. While the LaB6 emitted pulse, the minimum diameter of the focus decreased and wasnt more than 15um. The reason is that the heat accumulated on the foil-film, which enlarged the focus dimension, reduced remarkably.

当阴极采取连续发射电子的工作模式(发射电流40μA)时，记录测量到的最小电子束焦斑直径不大于22μm；而在相同条件下，以脉冲方式发射电子束时，其焦斑直径不大于15μm，原因是短时间的电子轰击减小了靶面的热堆积效应等。

A multilayer Laue lens with a 15-nm outermost zone width is designed for an incident X-ray beam with an energy of 8 keV.

针对入射光为8keV的X射线，设计了最外层宽度为15nm的多层膜Laue透镜。

The fine-beam diffraction of ferroelastic twins has been studied in detailfor the first time,and we have demonstrated the spot splitting of the a-typeferroelastic twin of NdP5O14 in its Laue pattern.With the help of computersimulation,the twin symmetry and structures were determined from the char-acteristics of the spot splitting.

在同步辐射微衍射中，我们首次在NPP a-型孪晶界的微衍射Laue图中发现Laue斑点分裂现象，结合NPP的自发应变，借助于计算机模拟，我们确定了这种挛晶的对称性与结构，并发展了一套利用同步辐射微衍射研究晶体中取向孪晶对称性的方法。

Now she was hungry and angry.She began to smoulder.

现在她又饿又气，她开始流露难以抑制的怒火。

You have placed our iniquities before You, Our secret sins in the light of Your presence.

诗90：8 你将我们的罪孽摆在你面前、将我们的隐恶摆在你面光之中。
