中文摘要：

本文在一个实际的科研项目的基础上，设计了一个基于CMB受体模型PM2．5源解析计算的共享实验，让学生从了解实验背景，熟悉CBM受体数学模型和有效方差算法，从共享数据服务器下载实验数据和相关软件与资料，到掌握NKCMBl．0软件的使用和计算，得到并解释计算结果，从而达到培养大学生创新创业和协作动手解决实际问题的能力．

英文摘要：

In this paper, as a practical research project, a shared experiment is designed based on a CMB receptor mathematical model and the PM2. 5 source apportionment calculation, in which the undergraduate students are re- quired to take part in the whole process--from learning the experiment background, the mathematical model and the efficient variance algorithm, to downloading the experiment data and the related software from the shared data server, to applying the software NKCMB1.0 for calculation, and to obtaining and interpreting the experiment results-so as to cultivate students＂ the ability of innovation and solving practical problems with cooperative spirit.
