摘要
从分析二维运动的测试原理入手 ,利用高速狭缝扫描摄影技术建立了测试系统 ,该系统能获得二维运动的轨迹和速度 ,从而把高速狭缝扫描摄影的研究领域由一维拓展到了二维 ,并对不同种测试系统进行了比较。利用新的测试系统获得了物体运动的照片 ,研究了质点高压下的运动 ,同时 。
By analysing the testing principle of two dimensional particle motion and applying the technology of high speed narrow gap scanning photography, a new testing system has been established. This system can acquire the locus and velocity of two dimensional particle motion. Thus the new testing system has widen the studying field of high speed narrow gap scanning photography from one dimension to two dimension. The author has compared two kinds of testing systems and gotten the photographs of body movement by using new testing system. Article motion has been studied under high pressure. At the same time, projection velocity and projection angles have been acquired.
