浙江泰顺洋滨含锡黄玉花岗质斑岩成因

浙江泰顺洋滨斑岩锡矿成矿母岩为黄玉花岗质斑岩脉,主要有黄玉钾长花岗斑岩(Ⅳ号脉),黄玉二长花岗斑岩(Ⅰ号脉深部)和黄英斑岩(Ⅰ号脉浅部)。组成基质的黄玉占全岩10-22％,具典型火成斑状结构。组成斑晶矿物主要有石英、条纹长石、钠长石和黑鳞云母。根据全岩高的F/Cl值(146-303),强过铝质(A/NKC=1.574～12.938)和K_2O>Na_2O等特点判断,在成因上与华南S型花岗岩相似。石英斑晶中含大量原生流体包裹体,其均一温度为180-472℃,含盐度为3.7～44.4wt％NaCl。此外还含少量不均匀包裹体,由数个结晶相(石英,云母和黄玉)和气液相组成,它是在流体/熔体不混溶作用下被捕获的。本文还从富F熔体的解聚作用,不混溶作用和反向演化等方面探讨本区岩石形成的机理

新加坡现代佛教建筑的发展

为分析新加坡现代佛教建筑在性格特征、建筑型制和功能要求的发展和变化,及探讨促使新加坡现代佛教发展的社会因素,在实地调查的基础上,通过相关文献的阅读,以天福宫和莲山双林寺为例,总结新加坡传统佛教寺院的特征.新加坡"改良佛教"的出现是促使新加坡现代佛教建筑发展的主要因素,文章进一步以新加坡佛教居士林和光明山宏船法师纪念堂为例,通过这两座现代佛教建筑与传统佛教寺院的比较,总结分析出新加坡现代佛教建筑的世俗化特征,灵活的建筑型制及多元化的功能这些与传统寺院迥然不同的特性.     

Genetic analysis and mapping of rice （Oryza sativa L.） male-sterile （OsMS-L） mutant

A rice male-sterile mutant OsMS-L of japonica cultivar 9522 background, was obtained in M4 population treated with ^60Co γ-Ray. Genetic analysis indicated that the male.sterile phenotype was controlled by a single recessive gene. Results of tissue section showed that at microspore stage, OsMS-L tapetum was retarded. Then tapetal calls expanded and microspores degenerated. No matured pollens were observed in OsMS-L anther locus. To map OsMS-L locus, an F2 population was constructed from the cross between the OsMS-L (japonica) and LongTeFu B(indica). Firstly, the OsMS-L locus was roughly mapped between two SSR markers, RM109 and RM7562 on chromosome 2. And then eleven polymorphic markers were developed for further fine fine-mapping. At last the OsMS-L locus was mapped between the two lnDel markers, Lhsl0 and Lhs6 with genetic distance of 0.4 cM, respectively. The region was delimited to 133 kb. All these results were useful for further cloning and functional analysis of OsMS-L.     

关于西部大开发的几点思考

邓小平“两个大局”的思想是实现我国地区经济协调发展和实施西部大开发战略的指导思想。实施西部大开发战略是实现共同富裕、保持社会稳定的迫切要求,是关系中华民族长远发展的战略之举,因此,它不仅是一个重大的经济决策,也是一个重大的政治决策,其意义极为深远。     

Predictive functional control （PFC） and its application in chlorinated polyethylene process

The main principle and the characteristic of Predictive Functional Control (PFC) strategy are presented in this paper and the corresponding control system aid design software APC-PFC is also introduced. For a chlorinated polyethylene (CPE) process, a design scheme of cascade predictive functional control system is described and the control performance is improved obviously.     

Genome sequence of Bacillus cereus and comparative analysis with Bacillus anthracis

Bacillus cereus is an opportunistic pathogen causing food poisoning manifested by diarrhoeal or emetic syndromes. It is closely related to the animal and human pathogen Bacillus anthracis and the insect pathogen Bacillus thuringiensis, the former being used as a biological weapon and the latter as a pesticide. B. anthracis and B. thuringiensis are readily distinguished from B. cereus by the presence of plasmid-borne specific toxins (B. anthracis and B. thuringiensis) and capsule (B. anthracis). But phylogenetic studies based on the analysis of chromosomal genes bring controversial results, and it is unclear whether B. cereus, B. anthracis and B. thuringiensis are varieties of the same species or different species. Here we report the sequencing and analysis of the type strain B. cereus ATCC 14579. The complete genome sequence of B. cereus ATCC 14579 together with the gapped genome of B. anthracis A2012 enables us to perform comparative analysis, and hence to identify the genes that are conserved between B. cereus and B. anthracis, and the genes that are unique for each species. We use the former to clarify the phylogeny of the cereus group, and the latter to determine plasmid-independent species-specific markers.
