1) Property theorem
性质定理
1.
The author extended the connected set s property theorem and made it possible to solve the problems perfectly which can t be solved by the previous theorem.
对连通集的性质定理予以推广 ,使得许多在原定理下不能解决的问题 ,得到了较为圆满的解答 。
2) theorem and property
定理和性质
3) understandings about the stability of traits
特质稳定性理解
1.
Eight short corrected stories were used to test 281 Chinese children which were 3-9 years old from kinder-gartens and elementary schools for their understandings about the stability of traits,not only positive or negative traits but also stability across time or situations.
五因素重复测量方差分析结果表明,3～9岁儿童对于特质稳定性的理解表现出随年龄发展稳定观不断增强的趋势,4岁可能是儿童特质稳定性理解由不成熟向成熟方向发展的关键点;此外,研究验证了年龄与特质性质的交互作用,也发现了问题类型和特质类型对特质稳定性理解的调节作用。
6) qualitative properties
定性性质
1.
Sign-oscillating property of stiffness matrix of difference discrete system and qualitative properties of beam with overhang
外伸梁差分离散系统刚度矩阵的符号振荡性及其定性性质
2.
The qualitative properties of the frequency spectrum and modes were studied extensively for the nonhomogeneous single span beams,in which the discrete and continuous systems were included.
采用差分法建立了两端任意支承多跨梁的差分离散模型,对只具有两端支承的单跨梁是正系统的情形,导出了对应的多跨梁差分离散系统的柔度系数;从单跨梁正系统的刚度矩阵的符号振荡性出发,通过引入辅助系统,讨论了多跨梁的柔度矩阵的振荡性,确定了对应于单跨梁正系统的多跨梁差分离散系统的频谱和模态的一系列定性性质。
