Under the catalyst, the polymerization retarder, the including water medicinal preparation existence condition, the methylacrylic acid and the polyethylene glycol single methyl ether (400) direct esterification synthesis methylacrylic acid polyethylene glycol single methyl ether (400) ester, and the influence factors of the catalyst, polymerization retarder, including water medicinal preparation has mellowly carried on the comparison.

摘要在催化剂、阻聚剂、带水剂存在的条件下，由甲基丙烯酸与聚乙二醇单甲醚(400)直接酯化合成甲基丙烯酸聚乙二醇单甲醚(400)酯，并对酸醇比、催化剂、阻聚剂、带水剂等影响因素进行了比较。

SHRIMP technique is applied to the age determination of Shuiquangou alkalic complex. Zircons from monzonite and syenite of the complex in the Dongping and Hougou gold mining district are dated at age of (390± 6) Ma and (386±6) Ma, respectively with U-Pb method. Rock-forming times of the complex is confidently constrained in the Late Caledonian-Early Hercynian period.

采用先进的SHRIMP测年技术对河北水泉沟碱性杂岩体进行了年龄测定，获得东坪金矿区水泉沟岩体二长岩锆石U-Pb年龄为(390±6)Ma，后沟金矿区水泉沟岩体正长岩年龄(386±6)Ma，比较可信地确定了水泉沟岩体的成岩时代为晚加里东期－早海西期。

OBJECTIVE: To explore the mechanism of tissue specificity of neurotropism in peripheral nerve regeneration, we investigated the biological characteristics of the nerve regeneration conditioned fluids on motoneuron of SD rats cultured in vitro.

目的 比较源于运动及感觉神经的再生条件液以及碱性成纤维细胞生长因子对体外分散培养的SD大鼠运动神经元的生物学效应，探讨周围神经再生趋化特异性产生的机制。

Objective To evaluate the accuracy of TCD and MRA in the diagnosis of occlusive and stenotic disorders of intracranial arteries.

目的 比较经颅多谱勒与磁共振血管成像对缺血性脑血管病颅内动脉狭窄或闭塞诊断的准确性。

The individual omnicompetence view prevailing in the early nineteenth century that anyone could be a lawyer was supported by "national principles of equality and democracy, by the American repudiation of class privileges…".

l 句子的主语比较长，故先译成一句19世纪初期，个人全权的观点非常流行，认为任何人均可成为律师。而美国"平等民主的国家原则"，"美国摈弃阶级特权"的思想，则是对这一观点的支持。

This paper presents an evaluation method based on psychological scale. Rank-order method or method of paired comparison is adopted to sort the images retrieved by different algorithms, then an ordinal scale is obtained. With presupposition of normal distribution, an equal interval scale is also obtained though POZ conversion. Thus different algorithms can be compared on these scales.

本文提出基于心理量表的情感图像检索性能评价方法，采用等级排列法或对偶比较法对不同算法检索出的图像进行排序，建立顺序量表，并在样本满足正态分布假设的前提下，将顺序量表转化成等距量表，以比较检索算法的优劣。

Objective: to compare three sets of fluorescence microscopy imaging systems with each other applied in study of subcellular localization of domestic new photosensitizer HMME.

目的：对三套荧光显微成像系统在国产新型光敏剂HMME亚细胞定位研究中的应用特点及适用范围进行了比较与评价。

The results indicated that the copper complexes have the best catalytic effect, and the high temperature of decomposition is dropped 129.01℃at most, the second is nickel complexes, and the catalytic effect is the smallest for the plumbum complexes.

有的催化剂的加入改变了AP的热分解过程，使AP的低温和高温分解峰合并成了一个峰，如7#、13#含铜配合物和8#含镍配合物，对AP的催化效果比较有效。

Methods Fifty-six patients with colon polypus (214 polypus) were subjected to perform CTC and colonoscopy.

方法收集行CTC和结肠镜检查的结肠息肉患者56例(共214个息肉)，对结肠息肉病例的三维成像方法(SSD、CTVC、PE)分别进行图像质量、病变检出时间、病变检出率等的评价，并与结肠镜比较。

The model of programmed crystallization of SPM was proposed based on the moment transformation of the population considering the agglomeration. The optimal temperature-time curves in a batch crystallizer which maximized the terminal mean size and mean weight size can be determined from the application of the Pontryagin Maximum Principle. The calculated crystallization results heating under optimal temperature were compared with ones under linear or natural heating temperature.

根据第四章所得到的螺旋霉素晶体二次成核和晶体生长和布朗扩散引起的聚集动力学，利用第六章所描述的晶体尺寸分布的各阶矩对时间的一阶导数所构成的自封闭的一阶常微分方程组，采用庞得里亚金极大值原理，以温度为控制变量，在满足某些约束条件下，以最大平均尺寸和最大晶体重量平均尺寸为性能指标，计算出了螺旋霉素间歇结晶的最优温度—时间曲线，并同线性加热和自然方式进行了比较。
