摘　　要：应用投影寻踪回归技术,对非正态、非线性悬栅消能率实验数据,用1/5数据建模拟合,4/5数据留做预留检验,拟合合格率92%,预留检验合格率92%,并与激光测速得出的消能率及原型观测的消能率完全吻合.Testing of non,normal and non,linear suspended grids using projection pursuit regression technique to collect their dumping ratio data is described in this article. A 1/5 data was used to create the model with a fitted acceptance of 92% and a 4/5 data was retained for controlling use with an acceptance of 92%. These figures fully coincided with the dumping ratio data obtained by laser measurement and that of prototype observations.
