To get to know more about the usage of plants, kids went to the market to do a survey. They were very surprised to see many products are made of plants; They also did an experiment to get the chlorophyl from the leaves.

这两周，一年级的同学们分小组种植了各种植物，每次课前老师们都带领学生认真观察植物的变化，辅导他们做观察记录，孩子们乐此不疲；为了了解植物的作用，同学们去菜市场做调查探究，他们惊奇地发现植物与我们的生活息息相关；我们还让学生们走进实验室，学习如何提取叶绿色，感受科学试验的神奇。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
