摘　　要：针对进口加沙控制系统的稳定性问题,采用回归分析方法,对模型黄河“小浪底至苏泗庄动床河道模型”进口加沙控制系统的稳定性和误差进行了研究,结果表明:进口加沙虽然存在一定的控制误差,但进口加沙控制系统基本稳定,满足动床模型试验规范的要求.For stability of the sediment feeding system at the inlet, based on statistical regression analysis, the stability and error of the sediment feeding system at the inlet is studied about the mobile bed model for Xiaolangdi-Susizhuang Channel of the Lower Yellow River, the result indicates that the system is basically stable and able to meet the requirement for experiment in spite of errors of certain controlling errors.

关 键 词：进口加沙控制系统 动床模型 稳定性 回归方程 方差分析
