On the other hand, 3(2)-fluoro-4-methoxyl methyl benzyl alcohol and 3(2)-fluoro-4-methyl benzyl alcohol are mixture and components of pyrethrum esters. Both of them have "mixture fluorine effect " and higher activity, lower drug resistance. As we know, the mixture benzyl alcohol containing fluorine is more easy to be synthesized than the single, so the cost of preparation is lower. We hope to apply it to molecule design of the new agriculture chemical. On the base of molecule design and structure-activity relationship research of pyrethric acid II and mixture of alcohol containing fluorine, we intend to get new pyrethrum ester that have higher activity and lower resistance.

另一方面，混合含氟对甲氧甲基苄醇和混合含氟对甲苄醇都是具有"混合氟效应"的高活性、低抗性的拟除虫菊酯醇组分，由于混合含氟醇的合成要比单一异构体的合成容易，成本较低，本文希望将其应用到新农药的分子设计中，用第二菊酸和一些含氟醇进行分子设计及进一步的构效关系的研究，筛选出一些高活性低抗性的拟除虫菊酯换代新品种。

Objective To study the mechanisms and treatment of ischemia /reperfusion injury, expression of intracellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) were measured, the effect on suppression of ICAM-1 and VCAM-1 by the pyrrolidine dithiocarbamate were investigated.

The molecular compositions of PCE-CGH and PCE-CGL were investigated by chromatography and chemical analysis. Rhamnose, arabinose, glucose and galactose were proved to be the main strctural unit of PCE-CGH, and trifle glucoronic acid was identified in the molecule. The compositions of PCE-CGL were relatively complicated. Inositol and amino sugars besides for glucose and galactose were also identified in its molecule.

其中，PCE-CGH主要是以鼠李糖、阿拉伯糖、葡萄糖和半乳糖为结构单元的大分子多糖类物质，并含有少量的己糖醛酸；PCE-CGL的分子组成相对复杂，除含有葡萄糖和半乳糖外，还含有一定量的肌醇和氨基糖。

Its absorption by a molecule causes all sorts of subtle changes in the vibrational or rotational energy of the molecule.

一个分子能吸收红外光引起分子中振动能量和旋转能量的各种各样的微小变化。

Based on our recent discovery on single molecule detection, scilicet molecular counts decrease with the increase of molecular weight, we also studied heparin-G-CSF interaction at single molecule level.

实现了调亡细胞活性氧类和谷胱甘肽的同时检测，以及细胞样品RNA的完整性评价，并取得了单细胞裂解和内涵物测定的初步结果。

This model of semiconservative replication-conservative because each new molecule has one half of the former parent molecule-was later confirmed by the work of Meselson and Stahl.

这个DNA复制模型称为"半保留复制"，因为两个新的DNA双螺旋分子中各含有一条母链。此模型之后得到了梅塞尔森和斯塔尔的证实。
