emission scan meaning in Chinese
发射扫描
Examples
- Field emission scanning electron microscope
场发射扫描电子显微镜 - The cenosphere particles were characterized with optical microscope , field emission scanning electron microscopy ( fesem ) , energy - dispersive spectroscopy ( eds ) and x - ray diffraction ( xrd ) in and after the plating
用光学显微镜、场发射扫描电子显微镜、能谱仪和x射线衍射仪对其进行了分析表征。 - Surface morphology and composition of the a1 film were characterized with field emission scanning electron microscopy ( fesem ) and energy dispersive spectroscopy ( eds ) to optimize a1 film growth conditions
利用场发射扫描电镜( fesem )及能量散射谱( eds )分析仪对沉积的铝层进行了表面形貌的表征和化学组分的分析。 - In chapter two , we fabricated r - ni - fe / al2o3 nanocomposites successfully by using ball - milling mixing method plus hot - pressing process . meanwhile , their microstructures are characterized by x - ray diffraction ( xrd ) analyser , transmission electron microscopy ( tem ) , field emission scanning electron microscopy ( fe - sem ) and brunauer - emmett - teller ( bet ) . the results indicate that ni - fe particles are homogenously dispersed in the matrix in the composites
在第二章中，我们采用高能球磨混合方法加上热压烧结工艺，成功制备了ni - 20fe al _ 2o _ 3纳米复合材料，并通过x射线衍射仪( xrd ) 、透射电镜( tem ) 、场发射扫描电镜( fe - sem ) 、比表面孔隙仪( bet )对该复合材料的微结构进行了表征。 - The data acquisition of the pet has several kind of mode . there are deferent mode divided by deferent standard . there are empty scan , trans - scan and emission scan . the emission scan could be divided into 2d and 3d by space and be divided into static scan , dynamic scan , gated scan and whole body scan
Pet的数据采集有很多种工作方式，从不同的角度有不同的划分方法，例如我们从临床角度将采集模式分为：空白扫描、透射扫描和发射扫描。发射扫描又可从空间上分为2d和3d方式；从时间上分为静态扫描，动态和门控采集，此外还有全身采集。
