In China, Zhou Ninghuai and others began to go on micro-scale experiment research firstly and Professor Li Qingshan who brought this innovation to polymer organic synthesis experiment has done a lot of works in micro-polymer chemistry experiment teaching. To carry out the study of micro-polymer chemistry experiments not only accords with teaching methods and reform, but also conforms to the trend of the times of green chemistry. So the research and application of micro-polymer chemistry experiment have broad prospects.展开更多

This software has the function of the automatic processing the experimental data, the automatic generation of test report copies, and the automatic evaluation of students' experimental results, which solve the reliability, objectivity and accuracy problems of the students' experiment data processing and evaluation, and avoid interference with human factors. The software has the characteristic of the easy installation, the easy operation, the strong practicability, pertinence, the systematicness and the running stability, so it provides a platform in the quantitative analysis chemistry experiment for the students' assessment system of automatic processing, and it has a high popularization value. The project's technical route design is reasonable, the research method is correct, and the experimental data processing results are reliable, which has reached the leading domestic level in the quantitative analysis chemistry experiment teaching field of computer data processing. And this project has been through the achievements appraisal of Gansu Provincial Sci. & Tech. Department.展开更多
