| 摘 要： | 粒子场测量技术目前广泛用于气液、气固两相流中，但是在等离子体流场中的粒子测量目前尚未很好解决。本文采用序列脉冲激光屏多次曝光摄影法，克服了流场的严重干扰，在电弧加热器等离子体流场中，对飞行速度达２０００ｍ／ｓ的粒子实验获得成功，得到某一截面内粒子的尺寸、空间分布及数密度等参数。

| Abstract: | Particles measurement technique is usually used in twophase flows of air-liquid and air-solid, but there are some difficultics used in plasma field, this paper provides a pulse light sheet technique of YAG laser which can solve this difficult problem. The experiment is achieved in plasma field with arc- heater. The size, distribution, numberdensity of particles in a plane at speed coin o up to 200 m/s are obtained. |
