| 摘 要： | 对林下山参高效液相色谱指纹图谱进行研究,运用SPSS16.0软件包,先对样品进行相似度分析,然后用聚类分析方法对林下山参样品的主要7种人参皂苷进行分类研究,对样品进行合理的分类,揭示样品间的远近亲疏关系,这可大大缩减了以往全凭主观判断所造成的误差,使数据分析结果更具客观性,对林下山参品种与质量的鉴定有一定的理论意义和实用价值。

| Abstract: | Robot teaching in universities has become more and more popular. In order to train students’practical operation ability and improve teaching effect，a practical teaching robot mobile chassis system is designed and realized. The mechanical structure of the system uses a three-wheel universal structure and a brushless motor drive scheme，and the communication interface between the chassis and the host computer uses the WiFi protocol. A complete control interaction protocol is designed，which defines different control and communication frame structures to complete the mobile control and information interaction of the robot chassis，and it is convenient for students to control and develop. The testing and trial prove that the function can meet the needs of robot teaching and related scientific and technological innovation activities. |
