The word sketchy here is not pejorative because millennia of philosophy of language have shown how hard (or even impossible) it is to come up with a truly rigorous model of natural language.
这里说粗略并非轻视，因为数千年来的语言哲学表明要建立自然语言真正严格意义上的模型是很难的(甚至是不可能的)。
Simulation results show that the simplified model provided by this method can satisfactorily imitate rigorous model in addition to its simple structure and feasibility for on line applications.
仿真结果表明，用本文提出的简化模型能较好地逼近基于偏微分方程的严格模型，且结构简单，易于应用。
