PRELIMINARY STUDY ON GENERAL UNIT METHOD IN DETERMINING THE AMOUNT OF SUBSTANCE;

“广义单元法”确定物质的量初探

In this paper,the concepts and the applications of amount of substance and extent of reaction have been discussed.

本文对化学教学中的物质的量和反应进度的概念和应用进行了讨论,并对它们之间的联系和区别进行了辨析。

The stoichometry relationships,the most important one in the titration calcdus, may by solved easily at the key level──the amount of substance by making validly use of the flexibility of the “mol ”when to be applied.

在滴定分析计算中，通过有效地利用摩尔这个ＳＩ单位在应用时的灵活性，可以在物质的量这个最基本的层次上方便地解决物质间的计量关系问题，而且对不同类型的滴定分析，无论其反应式以何种形式写出，也不管物质的表述形式需要限定为哪种基本单元，都可得到具有同一形式的计量关系式，整个计算方法，具有规范、简明、灵活而且重点突出的特点。

By using pin on disk dry sliding testing apparatus the material transference behaviour is systematically investigated in this paper.

采用销－盘式干摩擦磨损试验机，系统地研究了含磷蠕墨铸铁／４０Ｃｒ钢干摩擦副摩擦过程中质的转移规律。

Exploration of Modern Educational Software by Qualitative Research Method;

用质的研究方法探讨当代大学教育软件

The premise of integrating these two methods is to de-emphasize the terms of quantitative and qualitative research and put these.

要对质的研究方法与量的研究方法进行整合,首先必须"去范式",将研究的重点聚焦于研究问题,而非范式;其次必须将质性的资料与定量的资料放在同一个层面上进行比较。

By means of qualitative study, the paper makes a case study of Lu Zhiwen, principal general of Xiangyu Education Group and thereby enquires into the process, characteristics and regularity of the successes of outstanding school principals.

本文采用质的研究方法 ,对卢志文校长开展个案研究 ,以此探索名校长成功的过程、特点及其规律。
