The principle and its application of the measurement method using statistical analysis of visualized flow image have been shown.A new algorithm for the image measurement technique has developed using the passing probability of a particle. The method is extended by the Lagrange's differentiation to generalized case such as spatio-temporal derivative method. Of course, this method is effective for steady flow and also for the measurement of time average flow velocity filed only. It is useful, however, for the measurement of wake distribution behind ship, for which it takes long time by Pitot Tube. It is also possible to measure the three-dimensional velocity vector. A new fluorescent tracer particle has developed using synthetic adsorbent and rhodamine-B.in this research. It is applicable to the other PIV measurement.

介绍了可视化流动图像统计分析测量方法的原理及其应用，提出了一种利用颗粒通过概率进行图像测量的新算法。通过拉格朗日微分将该方法推广到一般情况，如时空导数方法。当然，这种方法对于恒定流也是有效的，而且只适用于时间平均速度场的测量。然而，它对于测量船后尾迹分布是有用的，而皮托管需要很长时间才能完成这项工作。也可以测量三维速度矢量。利用合成吸附剂和罗丹明B研制了一种新的荧光示踪剂颗粒。该方法适用于其他PIV的测量。
