14.In this paper,the mechanism of workpiece burn during grinding of casehardened steel and titanium alloys was studied by the use of SEM,EPMA,XPS and the metallograph analysis.
15.The cross section morphology and skin-core structure of PAN fiber in wet-spinning are analyzed by the means of electron probe microanalyser (EPMA) and scanning electron microscope (SEM).
16.Because the distribution of molecular director was not affected by lamellar decorating after quench, chemical etching and SEM technique were used to reveal disclination and director patterns.
17.The effects of double coating on the pores of lime titania type stainless steel electrode are studied with high speed cinecamera, oscillograph, optical microscope, SEM with EDS, etc.
18.The star cracks in macrostructure appear in some hypo-peritectic continuous cast alloy blooms and these cracks cannot be stuck completely by hot rolling reduction ratio,macroetching testing and SEM.
9.Now that we understand the transmission electron microscope, let's look at the Scanning Electron Microscope or SEM which Thermo Fisher Scientific also manufactures.
10.Transmission Electron Microscopes are typically more complex than SEMs and have a resolution up to 50 picometers, which is roughly the size of a hydrogen atom.
11.This microscope is similar to the TEM, but like the SEM, we focus the beam into a spot and then use deflection coils to scan the spot through the specimen.
该显微镜与 TEM 相似，但与 SEM 一样， 我们将光束聚焦到一个点， 然后使用偏转线圈通过样本扫描该点。机翻
12.The main idea is that, instead of illuminating an area of a specimen and imprinting the image all at once, with a SEM we create a focused spot, and scan this spot across the object we're trying to magnify.
其主要思想， 我们不照亮标本的某个区域并一次性印上图，而用 SEM 创建一个聚焦点，然后用这个点扫描我们要放大的物体。机翻
