It was the interactional result of electronegative double bond and branched chain with positive induction effect and space steri.

研究发现，加入不同的添加剂使润滑脂的油膜强度、锥入度和滴点产生不同的变化，并对其产生的原因作了机理分析，认为是由于极压抗磨添加剂分子中带负电性的双键和带正诱导效应及空间位阻效应的支链共同作用的结果。

The induction of TRAIL sensitivity by HCV core protein was due to facilitating activation of caspase-8 and its downstream pathway, and enhancing Bid processing, breakdown of mitochondrial transmembrane potential as well as cytochrome c release.

我们进而发现细胞对TRAIL敏感性的改变，是由於C型肝炎病毒的核心蛋白会促进caspase-8及其下游讯息分子的活化，这当中包括Bid活化、粒腺体膜电位的下降以及细胞色素c的释放。

Finally, the guideline for efficiently preparing core-shell structured capsule carrier was tentatively proposed.The cationic, neutral and anionic polysaccharides were separately acted as the liquid core of biomimetic capsule by mimicking the component and function of cell sap. It was found that the electrostatic repulsion interaction between the polysaccharide core and the enzyme enhanced the enzyme activity and stability.

首先，模仿细胞液的成分和功能选用三种具有不同电性的多糖(羧甲基纤维素钠、甲基纤维素和羧甲基壳聚糖钠)作为仿生微囊的液核，经比较可知，与酶分子具有静电排斥作用的多糖更有利于酶构象、活力的维持和酶稳定性的提高；然后，模仿细胞膜的结构和功能构建仿生微囊的壳膜。

And it is also a check point to understand the physical chemical properties of the unique aggregates.

在没有外加能量的条件下，由单体分子、胶束或双层膜如何自发转变为囊泡，以及自发形成的囊泡的稳定性一直是近期研究的热点，也是弄清这一特殊的聚集体的物理化学性质的瓶颈。

Capsici has been broadened, there is considerable diversity in host-specific pathogenicity. The isolates of P. capsici in Taiwan belonged to A1 mating type, and no chlamydospore was found. The structure or survival of P. capsici in the field is unkown.

目前在台湾所分离到之茄科疫病菌菌株均为A1配对型，且尚未发现其具有厚膜孢子，故在自然界中此病原菌是以何种构造或方式残存仍属未知，故分子标记之建立可协助该菌在自然界中之生态研究。

Objective To study the effects of mifepristone on the expression of IL6 in human decidua and chorion of early pregnancy in order to explore the molecular immune mechanism of mifepristoneinduced abortion.

目的 观察IL6在早孕绒毛、蜕膜组织中的表达及米非司酮对其表达的影响，探讨药物流产的分子免疫作用机制。

The optimum conditions of the process for obtaining high- purity and recovery citral were determined by analyzing the relative content of citral with gas chromatography- mass spectrometry system.

用GC-MS联用仪对分离物中柠檬醛相对百分含量进行分析，实验表明，获得高纯度、高收率的柠檬醛的分子蒸馏的适宜工艺条件为：在蒸馏压力0.15Pa、蒸馏温度45℃、物料流量1滴/s、刮膜蒸馏转速370￣390r/min、冷却水温度4￣5℃。

"Dialysis In chemistry, separation of suspended colloidal particles from dissolved ions or small molecules via their unequal rates of diffusion through pores of semipermeable membranes (e.g., parchment, collodion, cellophane)."

渗析法：一种化学分离方法，利用通过半透膜微孔时扩散率的不同，分离悬浮的胶态粒子和溶于液体的离子或小分子的方法。
