摘要
研究了一种新型三维粒子测量技术—偏置圆速法（ＣＶＢ）． 先介绍ＣＶＢ系统装置，分析ＣＶＢ基本原理；然后讨论了偏移量ｒｔ 与各种参数的关系；并用ＣＶＢ测量几种已知运动，以此来考察ＣＶＢ的可靠性． 原理分析和实验结果表明ＣＶＢ用于三维粒子测量是可行的，也是可靠的．
A new technique for 3 Dimensional image velocimetry is presented. Based on circular velocity bias method, the three components of partical velocity can be simultaneously determined by a single camera. Theoretical analysis and typical experimental measurement for several movements are given. They show that CVB is feasible and reliable.
