X-Ray diffraction is used to study the three-dimensional structure of protein crystals. A different use of X-ray diffraction work involves assembled protein structures. The method was limited to materials that were relatively unchanged with time because of the need to obtain enough intensity for ...
x-ray diffraction实验1 X－rayDiffraction－ 化学与化学工程学院无机材料实验室 概述 1895年，W.C.Roentgen在研究阴极射线管时发现X射线。－－－X射线透视技术。19121912年，M.VonLaue以晶体为光栅，发现M.Von了X射线的衍射现象，确定了X射线的电磁波XX性质。X射线是种电磁辐射，波长比可见光短，介于紫外与γ射线...
X-ray diffraction如何读 英:[ˈeksrei diˈfrækʃən] 美:[ˈɛksˌre dɪˈfrækʃən] X-ray diffraction是什么意思 爱克斯光衍射 X-ray diffraction英英释义 Noun: the scattering of X rays by the atoms of a crystal; the diffraction pattern shows structure of the crysta...
能穿透一定厚度的物质(原子序数越小越容易),并能使荧光物质发光(X射线透视)、照相机胶片感光(X射线摄影)、使物质的原子电离激发(气体导电),生命组织中诱发生物效应(理疗)。 产生机理:阴极(e.g., 钨灯丝)通电加热释放热辐射自由电子,高压使其高速定向运动,轰击阳极(靶材Target)使其突然减速或停止,在此过程中运动...
