所以理论上学习效应和规模效应不同，尽管实际操作中由于不确定性和模糊的因果关系可能很难区分它们。
Thus learning effects are theoretically distinct from scale effects, even if in practice they my be hard to differentiate due to e.g. uncertainty and causal ambiguity.
在某种程度的定义的下的，因果关系是模糊的。
Cause and effect below a certain level of definition is blurred.
同时这些问题的存在与功能定位的模糊有着必然的因果关系。
Meanwhile, these problems have inevitable consequences with the vague function orientation.
方法：用VENSIM软件绘出系统因果关系图，采用模糊综合评判法评价系统。
Methods: using VENSIM soft to draw the system, and then using fuzzy comprehensive evaluation method to evaluate system.
