本文以译制片《魂断蓝桥》为分析对象，根据传播学影响受众对媒介及其内容的选择性行为理论，从受众选择性心理理论分析该译制片实现跨文化传播成功的因素，以期对当今的译制片有启迪和借鉴作用。

Methods: The telomerase activity in breast cancer cells and MRC-5 cell line were detected semi-quantitively by TRAP-ELISA assay. Virus proliferation as- say and cell viability assay were used to evaluate the proliferation and cytolysis selectivity of CNHK300, and the results were compared with those of wtAd5. The breast cancer cells were treated with CNHK300 combining paclitaxel to evaluate the killing effect of the combined regimen.

The resultant was hydrogenised to remove protective group of amino group, then the product was reacted with NaNO2 to give diazonium salt, which was conjugated with salicylic acid, hydroxybenzene, N-salicyloyl glycine acid to get azo derivatives of 4-ASA.

本文首先对4-ASA的氨基和羟基进行了选择性保护，通过氢化还原法选择性脱除氨基的保护基，然后将氢化产物制成重氮盐，通过与水杨酸、苯酚和水杨酰甘氨酸发生反应生成4-ASA的偶氮衍生物，最后在碱性条件下水解得到最终产物。

When used in LAB complex unit with multi-step hydrogenation process,DSH-1 selective hydrogenation catalyst,which contain noble metal Pd,can transmit diolefin s to olefins effectively,and has good activation and selectivity.

DSH -1型含贵金属Pd双烯选择性加氢催化剂与多段加氢工艺结合，应用于脱氢法生产直链烷基苯的联合装置中，能有效地将脱氢过程产生的双烯烃转化成单烯烃，具有很好的反应活性和选择性，且操作弹性大，工艺过程简单。

Direction is from generatrix to branch. We improved the zero phrase power current protection principle and made out VAR high speed SCM and CAN bus technology base on this theory, which achieved much better outcome.

本设计研究和分析了基于零序有功功率的选择性漏电保护原理，并在此理论基础上研制了基于AVR高速单片机和CAN总线的选择性漏电保护系统，并在试验中取得了很好的效果。

This thesis discussed three kinds of major technologies to reduce high PAR on the basis of the principle of OFDM system: pre-distortion technology techniques (clipping and filtering, peak windowing and companding technique), code techniques (Reed-Muller coding algorithm of Golay complementary sequence), and scrambling techniques (selected mapping, partial transmit sequence and selective scrambling), these techniques have some certain limitations.

本文在介绍OFDM理论的基础上，专题讨论了抑制高峰值平均功率比的三类主流技术：信号预畸变技术(限幅滤波、窗函数和压扩技术)、信号编码技术(Golay互补序列的Reed-Muller编译码算法)和信号扰码技术(选择性映射技术、部分传输序列技术和选择性扰码)。

Omeprazole can be used as an in vivo probe to distinguish subjects between poor and extensive metabolizers of CYP2C19 activity according to the ratios of/-OPZ plasma concentrations after oral administration of the racemate.

本文首次研究了OPZ在中国健康男性受试者体内的立体选择性药代动力学行为，并与文献中的结果进行了比较，旨在深入研究OPZ体内代谢的立体选择性机理。

The extent of inhibition of depolarization by superfusion of ethanol for 5 minutes was 41.8±3.3 ％(n=17). The addition of 5 nM and 20 nM KT5720 (a selective protein kinase A inhibitor) and 250 μM H9 dihydrochloride (a non-selective protein kinase inhibitor), into the intracellular solution significantly attenuated the inhibitory effects of ethanol.

当分别将5 nM或20 nM KT5720（选择性蛋白质激酶A抑制剂）或250 μM H9 dihydrochoride（非选择性蛋白质激酶抑制剂）置入细胞内液时，乙醇的抑制作用明显被减弱；但乙醇的抑制作用不受到5 nM或20 nM calyculin A（磷酸酶1/2A抑制剂）的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
