中文摘要：

重要概念之间的理论关系或合理关系的连锁系统被称作是一个法则关系。法则关系包括原有模型、前因变量或结果变量。应用结构方程模型来检验法则关系中各组成部分之间的法则有效性，从而对原模型作进一步修正，该方法能够更加科学地揭示出多变量间的因果关系。文中还提到了应用法则关系方法时需要注意的问题，并指出未来的研究应当着重于进一步构建其理论框架、借助其来有效地开发和验证测量工具、以及探索该方法效度的影响因素等方向。

英文摘要：

One nomological network consists of the original model, antecedents, or consequences. Through the application of Structural Equation Model, researchers can test the nomological validity of various components and modify the original model. According to nomological network, the causation among multi-variables can also be scientifically revealed. And the problems which need to be pay attention to were discussed. Based on theoretical study and empirical study, researchers may （1） structure the basic theoretical framework of nomological network, （2） develop and validate measuring tools effectively by applying this method, （3） explore the influential factors of the validity.
