Darkness as a function of exposure is presented for the detecting and recording system, NNU-4 scintillator intensifying screen and Tianjin X - ⅲ film at low and room temperatures respectively. 给出了NNU-4闪烁增强屏天津X-Ⅲ胶片显示、记录系统在常温和低温下的黑度辐照量特性曲线。
Activate the Dashboard, then click the plus sign in the bottom-left corner of the screen; next, click the X in the upper-left corner of any widgets that you won't miss. 激活仪表盘,点击屏幕底部左边的+号;然后点击任何你可以在右上角看到的X符号,你不会错过它们的。
Objective : To study the relation between the contact of screen film and the contrast of X ray. 目的通过实验,对医用暗盒中屏片接触的紧密程度与X射线影像对比度关系进行探讨。
This is the result of Rare earth intensifying screen, which absorbs and converts more x radiation to visible light than screen made with calcium tungstate. 这主要是由于稀土增感屏比钨酸钙增感屏有较高的X线吸收效率及转换为可见光的效率。
So next time you click on a vert or a face or an edge the screen mode instead of saying thinking you may only want to move X or only want to move Y. 下次你点击一个点、一个面或者对象的边缘的时候,屏幕模式会辨认出你不是只想移动X或者只想移动Y。
