介绍两种动机测验及其形式:1)多元动机测验(MMG)及其半投射测验形式和网格技术,它综合了投射测验和问卷的优点;2)客观性成就动机测验(OAMT)及其通过被试完成操作性任务测评成就动机的客观性测验形式。
2) projective semimodule
投射半模
1.
In the first part,we proof that tensor product of projective semimodules is still projective;In second part,we construct the equivalence condition of projective semimodule and Hom exact sequence.
第一部分在[3]中张量积的定义下证明了投射半模的张量积仍是投射的;第二部分在文献[4]正合列的定义下建立了投射半模与函子正合列的等价条件。
2.

研究可补半环上的内射半模与投射半模性质。
3.
we define the projective semimodule in the category of semimodules and study some properties of the projective semimodule Furthermore, we prove that a left R-semimodule is projective if and only if it is a retract of a free left R-semimodul
给出了半模范畴中投射半模的概念 ,讨论了投射半模的若干性质 ,进而证明了一个左R-半模投射的充分必要条件是它是一个自由左R -半模的收

In the category of star semimodules, based on [1,2,3,4,5], we define exact sequences and short exact sequences, projective star semimodules and injecdve star semi-modules , and so on.
本文在文[1，2，3，4，5]的基础上，定义了星半模正合列，短正合列，投射星半模以及内射星半模等概念，讨论了星半模范畴中正合列的一些性质，得到了星半模上的“五引理”，并进一步讨论了投射星半模，内射星半模与函子Hom的一些性质。
5) Nk-projective semimodules
Nk-投射半模
1.
In this paper,we principally introduce the concept of Nk-projective semimodules,combining the theories of projective modules and projective semimodules with Nk-projective semimodules,we get some properties of Nk-projective semimodules,which are the generalization of some properties of projective modules and projective semimodules.
主要引进了Nk-投射半模的概念,并结合环中投射模与半环中投射半模的性质,得到了关于Nk-投射半模的一些性质,这些性质是投射模与投射半模性质的推广。
