PNT

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。

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MonteCarlo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。

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%。

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。

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。

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，BoxCox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。

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。

The reduction of p-nitrobenzene ( PNT ) and m-dinitrobenzene ( MDNB ) in three kinds of soils by zero-valent iron ( ZVI ) at normal temperature and pressure was studied using gas chromatography-mass spectrometry ( GC-MS ) .

用气相色谱-质谱联用仪（GC-MS）对零价铁在常温常压下还原3种土壤中对硝基苯和间二硝基苯进行了研究。

Under the optimal reaction conditions , molar amount of PEG & 600,5 % , molar ratio of KMnO_4 to PNT , 3 ∶ 1 , reaction temperature , 95 ℃, reaction time , 3 h , the yield of PNBA was 51.6 % in neutral reaction system .
