pnt怎么记

This thesis combines the object-oriented ideas with the basic theory of Petri nets to develop a visual tool of Petri nets and the simulation of the flexible manufacturing systems. A PNT is a type of files to represent the information of Petri nets.

本文将面向对象的思想和Petri网基本理论相结合，开发出Petri网可视化工具并对相应的柔性制造系统（FMS）模型进行仿真。PNT文件是一种保存Petri网信息的文件。

Results indicate that the Box-Cox approach provides better normality for data transforms, but in the case of evaluation by the statistical properties of the estimations on quantiles through reverse transform, the PNT is superior to Box-Cox method.

研究表明，Box Cox变换后样本的正态性更优，若以反变换后对水文设计值估计的统计性能评价，则以多项式正态变换的效果更优。

The skills of nursing operation in the students of the experimental group before and after studying PNT, the abilities of the students during the practical training and after graduation in the two groups, and the employment in the two groups were all investigated.

然后对实验组学生学习《护技》课前后护理操作技术掌握情况、两组学生实习期间及毕业后工作的综合能力、两组学生就业情况进行跟踪调查。
