The relative permittivity calculated from the high frequency value of impedance spectra,was used as the index to monitor properties variation with immersion time.

结果表明，涂层在流动的条件下加速失效，失效的原因是液体的流动加速了溶液中离子，而不是水分子向涂层中的渗透。

Thedissertation discusses in detail on the implementation of the algorithm, and applies it toanalyze the scattering from the conductor objects, dielectric objects, and microstrip patchantenna. The solenoidal basis functions are adopted in the scattering analysis of dielectricobjects, which lead to a less number of unknowns for the same mesh as in the traditionalSchaubert-Wilton-Glisson basis functions.

第三种快速方法是多层快速多极子加速电磁分析算法，它应用在时谐电磁场问题时将存储量及计算复杂度都降低到O，并且适用于任意形状的网格离散，具有很强的灵活性，文中将这一加速算法应用到金属体、介质体、以及无限大底板的微带结构的电磁散射特性分析中。

However, there is no difference for NAT2 rapid and slow acetylator between two groups.

吃红烧鱼因素在NAT2的快速酶中，特别是在野生纯合型中直肠腺瘤复发的相对危险度有增高趋势，提示了NAT2〓4等位基因编码快酶型NAT，可能在红烧鱼产生的杂环胺类化合物中代谢中加速其N-乙酰基化代谢过程，从而加速其代谢为终致癌物而与肠粘膜上皮细胞的DNA产生加成物，损伤其遗传物质。

Nevertheless, Smoking could interact with wild type of NAT2 and increase the relative risk of rectal adenoma recurrence significantly. It is suggested that NAT2 might involve the metabolism of pre-carcinogen generating from tobacco and alter the susceptibility of cancer. Meanwhile, the NAT2〓4 alleles encode rapid acetylator of NAT2 would increase the risk of adenoma recurrence among those high-risk people with habit of fried fish intake.

This thesis aims at above-mentioned objective condition, putting forward research of control means for variable appendiculate force,my purpose is bring forward a kind of detect method for car carried electronical antiskid devices, together with theory analysis and simulation experiment towards control means.

ASR，全称是加速防滑控制系统，它是在ABS基础上新发展起来的一种新装置，其作用是防止车辆在起步或急加速时驱动轮打滑，以维持车辆行驶方向的稳定性，保持灵敏的操控性和适当的驱动力，确保行车安全。

The results indicate that in the process of dissimilatory metal reduction, NTA and AQDS can accelerate the speed of ferric oxides reduction and magnetite generation in the initial stage, but magnetite production prevents further iron reduction. Direct contact is a very important way, and the biomembrane formed by adsorption for long time is a critical factor for reduction.

结果表明，微生物异化还原铁氧化矿时，NTA，AQDS在初始阶段显著加速铁氧化物的还原，但也加速磁铁矿的生成，阻碍反应继续进行；直接接触方式起着重要作用，吸附形成的生物膜是一个关键因素，其形成是一个相对较长的过程。

Compared with traditional vector filtering, our new algorithm can filter out more irrelated tuples and improves the performance with 10%.

本文还研究了连接运算的加速技术，针对传统的位向量过滤技术的不足，提出了对称位向量加速技术和动态内外关系角色转换的Hybrid-Hash连接算法。
