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。     

机动巨标跟踪的自适应混合多模算法

本文介绍了用于机动目标跟踪的自适应混合多模算法.这个算法不需要预先定义模型,它利用一个二级卡尔曼滤波器来估计目标的加速度,这个加速度被用于混合多模算法中具有不同确定性加速度的子滤波器中.文中给出了自适应混合多模算法的一个计算机模拟结果并和无自适应混合多模算法的结果进行了比较.
