高压CMOS管工艺的设计、模拟和验证

模拟和验证了一种低成本的，以标准CMOS工艺为基础，无需对原工艺流程进行改动的高压工艺技术。讨论了低压器件中的各种击穿机理，相应提出了高压器件中所做出的改进，列举了该工艺技术中所用的特殊版图；对此工艺的应用性进行了二维的工艺和器件模拟；将模拟结果与实际测试结果进行了比较，验证了这种高压工艺技术的实用性。     

朝鲜推行全方位外交之背景分析

以“两金会晤”为转折点，朝鲜外交渐易常态，日益呈现出明显的全方位特征。朝鲜外交模式由保守单一到多边开放的转变是以后冷战时期朝鲜的一系列错综而深刻的国际国内因素为背景的。这决定了朝鲜推行全方位外交路线的战略性而非策略性。     

Host cell reactivation of ozone-treated T3 bacteriophage by different strains ofEscherichia coli

Summary Host cell reactivation capacity for ozone T3 phage was determined for differentE. coli strains deficient in one or more of the DNA repair mechanisms. The results indicate that DNA polymerase I appears to play a key role in the repair of damage produced on the DNA by ozone while thelexA gene product seems to play a minor one.This research was sponsored by the National Sciences and Engineering Council of Canada. One of us (PLH) acknowledges a scholarship from the NSERCof Canada.

Increased assembly of cytoskeletal proteins associated with the transformation of human liver cells into fibroblast-like cells.

A topoisomerase II inhibitor, novobiocin, and a deacetylase inhibitor, butyrate, synergistically transformed human liver cells into fibroblast-like cells. This morphological change was associated with an increased production of procollagen type III peptide and a simultaneous assembly of actin, tubulin, vimentin and cytokeratin. Novobiocin and butyrate had no marked effect on the phosphorylation state of cytokeratin proteins, but synergistically enhanced [3H]acetate uptake. From these results, it can be speculated that protein acetylation plays an important role in inducing the assembly of cytoskeletal proteins and the morphological transformation of human liver cells.

农业增长方式的转变使原本落后的农村职教面临着新的挑战。针对目前农村职业技术教育存在的问题,分析农业经济增长方式转变对农村职教的影响,进而提出新形势下发展农村职教的对策。     

以4,4''''-二(咪唑基亚甲基)联苯为客体的环糊精类轮烷的合成与表征

以4,4'-二(咪唑基亚甲基)联苯(bibp)为客体,通过自组装合成了4,4'-二(咪唑基亚甲基)联苯和环糊精的[3]类轮烷,并通过元素分析,1HNMR,ESI-MS,IR,TG-DSC进行了表征和固体热稳定性等研究,结果表明:由于bibp客体分子链较长,含有两个苯环,所以可穿入两个β-环糊精分子,形成[3]类轮烷.
