At the same time, due to the non-linear condition of time sequence, conventional linear Vector Autoregressive model can hardly characterize the causality among economic variables correctly.

同时由于时间序列的非线性，常规的线性向量自回归模型难以正确描述经济变量之间的因果关系。

Define the event dependence and the component dependence from a new method of event's causality and time sequence. Corresponding algorithms are also proposed.

从事件时序和因果关系的新角度，定义了事件依赖、构件依赖、构件系统依赖图等构件系统依赖性分析的概念，并给出提取这些依赖关系的算法。
