河南的红菇科真菌资源的研究（Ⅱ）

红菇属（Ｒｕｓｓｕｌａ）是红菇科（Ｒｕｓｓｕｌａｃｅａｅ）的一个重要的属。本文依据在河南山区采集的标本,鉴定、整理出红菇属的种类有３１种,其中食用菌２４种、药用菌４种、毒菌５种。此外,它们多是菌根菌,与林业有着密切的关系,还有不少种类的子实体中含有抗癌物质,具有抑制肿瘤的作用。

Discovery and character of the Kunlun-Yellow River Movement

Based on geomorphological, tectonic and sedimentary data, a Kunlun Yellow River Tectonic Movement has been recognized in 1 10-0 60 Ma B.P. This tectonic movement, which leads to uplift of the Qinghai_Xizang (Tibet) Plateau from 1 500 to 3 000-3 500 m, is periodic, abrupt and changeable in the movement rate of uplifting and slide slipping.     

Discovery of eclogite at northern margin of Qaidam Basin, NW China

Eclogite was first discovered at the northern margin of the Qaidam Basin in this study. It occurs as pods in the gneiss sequence of Middle to Upper Proterozoic age and is mainly composed of garnet, omphacite, phengite and rutile. The garnets contain 44%-62% of almandine, 15%-33% of grossular and 12%-30% of pyrope molecules, and the omphacites contain 40%-46% of jadeite. Applying garnet_clinopyroxene thermometry and jadeite geobarometry, the peak conditions of eclogite facies metamorphism occurred at about (722±123)℃ and at the pressure of up to c. 22 ×10 8 Pa.     

Effects of extracellular calmodulin on pollen germination and tube growth

The effects of calmoddin (CaM) antagonist W7-agarose, anti-CaM serum and exogenous purified CaM on pollen germination and tube growth ofForsythia suspensu were studied. The pollen germination and tube growth were inhibited or completely stopped by CaM antagonist W7-agarose. The addition of exogenous purified CaM stimulated pollen germination and tube growth, whereas the same amount of bovine serum albumin (BSA) had no effect. The inhibitory effects caused by W7-agarose and anti-CaM serum could be reversed completely by the addition of exogenous purified CaM. The tube growth of germinated pollen was also inhibited or completely stopped by W7-agarose. The results suggest that endogenous extracellular CaM initiates pollen germination and tube growth, whereas exogenous CaM enhances the above processes.     

平面型无参比电极二氧化硫传感器

制备了一种新型无参比电极由ＮＡＳＩＣＯＮ和ＹＳＺ两种固体电解质及Ｎａ２ＳＯ４辅助电极构成的二氧化硫传感器。实验结果表明,该传感器对二氧化硫产生Ｎｅｒｎｓｔ响应。由于这种传感器采用了平面结构,对比电极和工作电极处于同样气氛中,消除了氧的影响和密封问题,同时有利于传感器的微型化和多元复合。

电力系统潮流计算的模拟进化方法

将模拟进化方法引入电力系统潮流计算。与传统方法比较结果表明,模拟进化方法中的进化策略法可以有效地解决电力系统病态潮流问题。文中还对几种模拟进化方法进行了比较,结果表明：进化策略法用地潮流计算比较成功;基因算法和进化规划法由于方法本身的缺陷,不太适合于潮流计算。
