The BSD4 detector is used to detect backscattered electrons that have been scattered under very low angles. The COMPO-Mode is suitable to produce high quality material contrast, meaning heavy materials are displayed brighter than lightweight materials. ...

你说的是SEM电镜吧,这主要是它的成像原理导致的其可以反映样品表面或者断面的形貌信息。SEM的工作原理为:从电子枪阴极发出的直径20(m～30(m的电子束,受到阴阳极之间加速电压的作用,射向镜筒,经过聚光镜及物镜的会聚作用,缩小成直径约几毫微米的电子探针。在物镜上部的扫描线圈的作用下,电子探针在样品表面作光栅状...
As bonus, adding group node and group-genes edges, the pathway with several compo- nents (clusters) and singleton genes induces a connected graph (see Fig. 1). Thus we consider a directed graph G = (V ∪ X, E ∪ EX ) with the linear structural equations: Yj = βjX + Uj j ...

The correlations between the linguistic knowledge measures and the lan- guage component of the writing test were higher than those with the other compo- nents, given that the language component assessed language features used in writing. This finding aligns with Yoon's (2017) study, which ...
SEM的主要性能课件 SEM的主要性能：1，分辩率 二次电子和俄歇电子的分辩率高，特征X射线调制成显微图像的分辩率最低。电子束进入轻元素样品滴状作用体积 电子束进入重元素样品半球状作用体积 学习文档 影响SEM分辩率的三大因素：电子束的束斑大小，检测信号的类型以及检测部位的原子序数 SEM分辩率的测定方法：在已知的...
La composante analytique de la composante cruciale releve des principes de notre entendement, mais il y a aussi d'autres composantes, qui sont tacitement dictees par certaines structures modulaires contingentes de notre systeme cognitif (par exemple nos classes spontanees de similarite, nos ...
