有机同系物性质递变的基本规律

发现了有机同系物性质递变的两个基本规律：等差递变和等比递变。它们可分别表示为Ｐ＝ａ＋ｂｎ和Ｐ＝ｃ＋ｄａ”。式中Ｐ为同系物的某种性能，ｎ为同系物的重复结构单元数，ａ、ｂ、ｃ、ｄ和α为系数。研究结果表明，同系物的加和型性能一般遵守等差递变规律，如标准生成焓和临界体积等；结构型性能通常遵守等比递交规律，如电离能、电子亲和能、密度、沸点、粘度与表面张力等。

镧系元素性质递变的双峰现象

本文从镧系的电子结构和化学键参数分析了镧系元素性质遂变的双峰现象的本质。并探讨了它在稀土分离提取工艺方面应用的可能性。

元素周期系中的双峰效应

在总结和归纳周期系中的元素和化合物的一系列物理化学性质的基础上,我们发现元素周期系中存在一种可称为“双峰效应”的性质递变规律。本文论述了双峰效应的普遍性,并对双峰效应的实质和意义也作了简要讨论。

Evolution of neurotransmitter gamma-aminobutyric acid, glutamate and their receptors

Gamma-aminobutyric acid （GABA） and glutamate are two important amino acid neurotransmitters widely present in the nervous systems of mammals, insects, round worm, and platyhelminths, while their receptors are quite diversified across different animal phyla. However, the evolutionary mechanisms between the two conserved neurotransmitters and their diversified receptors remain elusive, and antagonistic interactions between GABA and glutamate signal transduction systems, in particular, have began to attract significant attention. In this review, we summarize the extant results on the origin and evolution of GABA and glutamate, as well as their receptors, and analyze possible evolutionary processes and phylogenetic relationships of various GABAs and glutamate receptors. We further discuss the evolutionary history of Excitatory/Neutral Amino Acid Transporter （EAAT）, a transport protein, which plays an important role in the GABA-glutamate ＂yin and yang＂ balanced regulation. Finally, based on current advances, we propose several potential directions of future research.

元素分论的总结与归纳

期末考试即将来临,为了帮助学生较好地掌握无机化学的课程内容,本文拟从各个侧面来启发学生把握住课程的重点,提醒学生应该注意的问题,督促学生有效地进行复习。关于总的要求,本学期授课的内容并不是百分之百地要求学生掌握,这里我们将所学内容分成三部分分别加以说明。第一部分:要求学生掌握的。譬如:元素电势图的计算与判断、各类反应的K值的含义,重要试剂的重要化学反应等。这部分内容是最基本的。要求学生能运用自如、举一反三。
