为了从船模试验资料中分离出航道水流的碍航作用，提出了一个“静水复演”的试验方法，即记录船模在航道航行的操纵过程，按此操纵过程在静水池中作复演试验，将二次试验航行参数进行向量迭加, 即可分离出影响船舶（队）航行的水流碍航参数。从而可认识口门区的斜流效应，得到斜流的特征量对船舶（队）的航行影响及其与斜流效应的关系。以三峡船闸上引航道为例，通过试验得到的斜流作用下船队的偏航距，其结果是基本合理的。

To separate the effect of oblique flow on navigable ship model in dynamic water, a duplication test method used in still water ship pond was put forward.The duplication test of the ship model in still water ship pond was implemented by using manipulated process recorded in dynamic water, the navigation parameters of two tests were taked to superpose together in vector, and then the distance of deviating sailing line due to the influence of oblique flow was obtained. Through the navigation test of TGP, the practical deviation distance was found, and the result is considered to be basically rational.
