MIXTURE ANALYSIS USING FACTOR ANALYSIS.Ⅱ:SELF-MODELING CURVE RESOLUTION

One of the major applications of factor analysis in the chemical literature,self-modeling curve resolution(SMCR),is covered in this review,including a historical account of the inethods derived from Lawtonand Sylvestre's original method.Papers treating the theory or applications of SMCR are included.Qualitative and quantitative applications are described where appropriate.     

Convective Boundary Layer in the Region of the Monsoon Trough-A Case Study

A case study of the convectively driven monsoon boundary layer has been carried out using the aerological observations at four stations in the region of monsoon trough during Monsoon Trough Boundary Layer Experiment (MONTBLEX) 1988. The Convective Boundary Layer (CBL) in the region of monsoon trough did not show double mixing line structure. A single mixing line representing the CBL with different stabilities with respect to the convective activities was observed.     

《中国天文地质事件》评述

该书的作者们独辟蹊径地研究整个显生宙地层剖面,其目的是从这些剖面可能揭示出一系列地外成因的事件。暂且不论这费劲的工作收益有多大,一个引人深思的问题在于,象这样一本书在10年前能否被接受并出版?但正是在这10年间,许多地质学家已注意到:他们研究的课题同天文学和天体物理学有联系。1980年出现了观念性的变化,在这之前,任何一种把     

印度马德拉斯含水层系统水文地球化学对人类健康的影响

从1985年开始,安娜大学水资源中心在马德拉斯含水层系统(MAS)有规律地进行了水文地球化学研究,该含水层系统包括北-西北部多层含水层和南部半承压含水层。马德拉斯大城市居民的60～70~*％,供水来自马德拉斯含水层系统,在干旱年份,近     

地质演化与生物演化体系(岩石学中的变成学派)

自古以来,metamorphism(变质作用,变异)就是一种用来描述形态变化,即转变的概念.这一术语具有特殊的含意,并且在不同的自然学科中有着不同的用法.在生物学中,“metamorphism”描述生长的变异,而在地质学中,则用它来表述在温度和压力相对增加的条件下,或者在地球营力的作用下,岩石的变形、重结晶和变晶生长.     

Methods Used to Study Bacterial Diversity in the Marine Environment around Qingdao

Pollution has a considerable effect on biological communities, in terms of size and diversity of the populations. Yet, the precise consequences of human activity on microbial communities in the marine environment are poorly understood. Therefore, in an ongoing collaborative research programme between Heriot-Watt University and the Ocean University of Qingdao, bacteria were isolated in 1999 and 2000 from marine sediment, seawater, seaweed, fish and shellfish, taken from locations in Shandong Province adjacent to Qingdao. Sampling locations were comprised of industrial and aquacultural sites and a clean, control site. In order to analyse microbial diversity, a polyphasic approach was adopted for characterisation of these isolates, specifically through examination of key phenotypic traits, i.e. using Biolog GN MicroPlateTM profiles, bacterial whole cell protein profiles and 16S and 23S rRNA gene sequences. These techniques yielded complex taxonomic data, which were subjected to statistical and cluster analyses. The application of these methods to studies of microbial communities is discussed.     

干旱地貌学研究进展

世界上许多沙漠在更新世确实急剧地扩大了(Goudie, 1981; Street,1981)。对于沙漠形成的时代,有了日益增多的证据,尤其是从深海结核沉积中得到的材料。远离西撒哈拉的沉积结核中还含有可以检定的风成物质,表明在约二千万年以前(早中新世)北非就存在着一个发育良好的干旱区(Diester-Haass and Schrader, 1979)。同样,斯埃瑟(Siesser, 1981)证明在晚中新世波恩古尔勒海流(Bengular Current)的寒冷上升流(upwelling water)造成了沿西南非洲(纳米比亚)纳米布海岸的干旱化。对北太平     

苏联社会经济地理学的任务

最近十年来,做为一门科学的地理学已经发生了重大的变化。现在,社会经济地理学形成了一种关于社会空间形式的知识体系。经济一地理这门学科的分化同时又是综合的趋向是和地理学研究当前强调与经济学、生态学与社会学方面的联系有关的。
