The addition reaction of diazo pyrazoles and isocyanate has been investigated and the mechanism of this reaction has been guessed.

研究了重氮基吡唑同异氰酸酯的环加成反应，初步推测了该反应的机理。利用此反应设计了一类可能具有生物活性的吡唑骈[5，1-d][1，2，3，5]四嗪-4-酮类衍生物。

If the Legislative Council passes the original bill again by not less than a two- thirds majority of all the members, the Chief Executive must sign and promulgate it within one month, or act in accordance with the provisions of Article 50 of this Law.

Kinesin is plentiful in various kinds of cells, different stages of cell development and multicellular organisms.

它是由两条120KDa的重链和两条70KDa的轻链构成的四聚体。

Furthermore, we propose and implement multilevel circuit partitioner. The achievements of the dissertation are as follows: During the coarsening phase, we propose thecore-sorted heavy-edge matching algorithm and give its details based on the compressed storage format of graph.

本文主要的工作和创新点有以下四个方面：在多水平粗化阶段提出了一种基于核排序的重边匹配算法，给出了基于图压缩存储格式的算法实现细节。

Chapter Four mainly deals with the conflict of laws aspect of transnational securities trade. Under the prevailing indirect securities holding system, traditional Lex rei sitae is no longer a proper connecting factor which calls for modifying.

第四章论述了跨国证券法律冲突的存在和传统冲突规范的失效，对当今证券间接持有体制下重订冲突规范的有关动向进行了跟踪研究。

关于你提到的美国《四年防务评估报告》的涉华内容，这份报告老调重谈，继续对中国正当、正常的国防建设说三道四，并且妄称中国"缺乏军事透明度"。

Less than one quarter of these high-risk deliveries occurred in high-level, high-volume facilities, yet 92% of very-low-birth-weight deliveries occurred in urban areas with more than 100 such deliveries, the researcher reported. This suggests that it would be geographically feasible to regionalize the vast majority of these deliveries in California.

不到四分之一的这些高风险婴儿是出生在高水平，大量病人的医院中，然而有92%极低出生体重婴儿出生在超过100个的市区，研究者报告，这说明在加利福尼亚州在地理学上更易于按地区找到绝大多数这些极低出生重婴儿。

Less than one quarter of these high-risk delieries occurred in high-leel, high-olume facilities, yet 92% of ery-low-birth-weight delieries occurred in urban areas with more than 100 such delieries, the researcher reported. This suggests that it would be geographically feasible to regionalize the ast majority of these delieries in California.
