钢液定氧测头响应时间和热平衡态

本文分别研究了ＺｒＯ２（ＭｇＯ）固体电解质管头壁厚，参比电极量对定氧测头响应时间的影响，得出了以ＺｒＯ２管头壁厚为０．６０－０．８０ｍｍ，Ｃｒ／Ｃｒ２Ｏ３参比电极加入量为４０－６０ｍｇ所组成的定氧测头响应速度最快，同时采用了“双偶法”对定氧测头在工作过程中的热平衡态进行了研究。结果表明：氧浓差电池中的传热是响应过程的控速步骤，氧电势曲线上峰值的产生是起源于电池中的热平衡态。

Isolation and purification of BVⅠ-2H from bee venom and analysis of its biological action

The medical use of bee venom for rheumatoid arthritis ( RA ) has a very long tradition. In this study, isolation and purification of polypeptides from bee venom were carried out on sephadex chromatography, heparin sepharose CL-6B chromatography and HPLC. Several fractions were extracted, and their effects on activation of splenocyte and THP-1 cell were studied. The inhibitory fraction was selected for further studies. Finally, BVⅠ-2H that the HPLC elution profiles was a single peak was isolated by C8 column. ESI- MS detection results showed that BVⅠ-2H was a fraction of bee venom, and the molecular weight of the major component was 644.8. BVⅠ-2H could inhibit ConA-induced splenocyte proliferation, IL-1 production and interfere with splenocyte cycle in mice. Moreover, BVⅠ-2H could inhibit PMA-induced TNFα production in THP-1 cells, which was due to its inhibitory effects on TNFα mRNA expression and protein phosphorylation of IκBα. Our studies indicated that BVⅠ-2H was one of the anti-inflammatory components of bee venom.

地方性高校教材建设初探

提出了地方性高校教材建设应包含的基本内容,认为:地方性高校教材建设应侧重于详细的教学大纲的编写和参考书目的编订;硬性规定学生入手一册同样的统编教材的做法是有害的,对于基础课程,教师应给学生指定几套参考书,专业课程要给学生予丰富的文献资料;适当引用国外优秀教材、改革教材管理机构是必要的.

精馏塔理论塔板数计算方法的评述及其新的简捷算法——图算法

化学工程中精馏塔的理论塔板数N是塔器设计的一个重要数据。它与最小回流比R_m、回流比R及最小理论塔板数N_m间具有一个复杂的函数关系,故其计算是相当麻烦的。本文对现有的各种较为简捷的算法进行了评述,并提出了一种极为简捷的算法——图算法。利用此法,无需进行数值计算,只用两条直线即可简捷地求出准确的结果。
