By measuring the variation of the X-ray count rate passing through the foam, the density of foam is precisely resolved. 通过测量X射线经靶材料吸收前后的强度变化,可较为精确地计算出待测样品的密度。
The evaluation system accepted CCD video frequency signal and read the count of the passing points in the 10-mill circle by automatism or half-automatism judgment to carry out 2-dimension image addition and 3-dimension data disposal, accordingly accomplish the evaluation of the firing results. 其判读系统接收CCD视频信号,经自动或半自动判读进行二维图像叠加及三维数据处理,得出10密位圈内的弹数,完成实弹射击成绩评定。
The article describes a new CCD camera-computer system, which can track the center of the light spot and count the number of fringes passing the center constantly ' So we can measure the substrate temperature by laser automatically ' 描写了一种新型的CCD摄像头一计算机系统,它可以在镀膜基板激光测温的过程中跟踪光斑中心,从而测出移过光斑中心的干涉条纹数,达到镀膜基板激光测温自动化的目的。
