探索了多重样本资料进行ＬＩＳＲＥＬ建模时，各参数矩阵的几种常见的制约形式。这使我们能够用统一模式拟合同一现象的多重资料，同时也可以通过检验多种制约形式来研判同一实际问题的理论模式
Explore the multiple sample data for LISREL modeling, several common matrix matrix of the constraints. This allows us to fit the multiple data of the same phenomenon in a uniform pattern and at the same time to examine the theoretical model of the same practical problem by examining a variety of constraints
