Second, the paper make a study about the implement of mathematics research study including the design principle of researching problem , content classification, teaching strategy.

论文的第四部分对研究性学习的实施做了研究，主要包括数学研究性学习的课题设计原则、内容分类、教学策略。

So the study makes an easy way for launching research of MLRS and prepares for applying some mathematics methods (such as CADET) in the statistic field of MLRS.

也为采用某些数学方法(如协方差描述函数法)进一步研究火箭发射系统的统计性能作了必备的前提工作。

Therefore the research study migration rule to achieve our mathematics teaching goal to have the extremely realistic significance.

所以研究学习迁移的规律对实现我们的数学教学目标具有非常现实的意义。
