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.

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.

Based on the general seismic design rule of structures, which is strong joint, weak member, another seismic design concept for steel structural end-plate connections, which is strong connection, weak plate is pnt forward.

本文还在“强节点，弱构件”抗震设计一般原则的基础上提出了“强连接，弱板件”的端板连接抗震设计概念。

Nitrobenzene compounds transformed into benzylamine compounds; the reduction rates of PNT and MDNB in clay were highest, reaching 91% and 90%, respectively.

结果表明，硝基苯类化合物转化为苯胺等化合物，对硝基苯和间二硝基苯2种化合物在黏土中的还原率分别达到91%和90%。

With the P-III distribution taken as an example, the statistical characteristics of the PNT method were investigated by means of the Monte-Carlo simulation.

以PⅢ型分布为例，用Monte Carlo法进行模拟分析，并对PNT法的统计性能与线性矩（LM）法的统计性能进行了比较。

Objective To explore the necessity of medical students learning "practical nursing technology" ( PNT).

目的探讨医学生学习《实用护理技术》（简称《护技》）课的必要性。

After a decade-long ban for links to Eta, the separatist group that recently ended its 50-year campaign of violence, political separatists won more seats than the PNV in municipal and general elections last year.

There is significant difference between the existing vegetation and PNV due to the influence of human activities.

由于受人类活动的影响，现存植被同潜在植被之间存在显著差异。

The PNW export program has been beset by weakened wheat exports and slower corn exports as compared to last year.

困扰太平洋西北沿岸的问题是，与去年相比，小麦的出口形势不佳，玉米的出口进度放慢。

It is introduced a new type of macromolecular phenolic high temperature antioxidant ( PNX).
