Moreover, the effects of the molar ratios of the reagents on the yield are examined. The best molar ratios are a 2.0 molar equivalence of thionyl chloride and a 3.0 molar equivalence of paminophenol to retinoic acid, and the total yield is 80.7%.

此外，研究了反应试剂的摩尔比对反应收率的影响，最佳摩尔比为二氯亚砜和对氨基苯酚物质的量分别是维甲酸物质的量的2倍和3倍，总收率为80.7%。

Three reservoir clay minerals such as montmorillonite, kaolinite and illite were selected. Alkali consumption was investigated to define coeffect between these minerals and their corresponding mixtures under three amount ratios, solid/liquid ratios, and at different temperature conditions.

选择蒙脱石，高岭石，伊利石等三种在储层中最常见的储层粘土矿物，两两分别按2：0，1：1，0：2质量配比组成复配物系列；在30℃、50℃温度下按1：5，1：8，1：10固/液比分别与1.6%的Na2CO3溶液反应8h、120h、360h；监测反应前后碱液浓度的变化；计算了各条件下各自的绝对碱耗量。

Almost all the vegetation types occurred in a small study area, so the present study was typical and representative. The results show that the corrosional ratios of different vegetation types at different elevations are quite different. In general, the corrosional ratios increase gradually from the forest land of Shuifang spring, through the bamboo forest land of Shuifang, the meadow of Shuifang and the forest of Bitan spring, to the shrub of Bitan spring.

测试结果表明不同植被条件甚至同一植被类型下不同海拔下岩溶区石灰岩标准试片的溶蚀速率都存在较大差异，5个测试点溶蚀量由大到小依次为水房泉竹林地、水房泉林地、水房泉草地、碧潭泉林地、碧潭泉灌草丛。

More clues to Coryphodon's lifestyle came from an analysis of ratios of carbon-13 to carbon-12, which exists in different ratios in various types of plants.

更多与冠齿兽生活习性有关的线索来自对碳-13与碳-12比例的分析，它们在不同类型的植物中有不同的比例。

Secondly, the method of hierarchical classification was adopted to divide 282 cities into 3 kinds, the first was mainly capital cities and vice-province cities; the second was mostly eastern coastal cities and some middle cities; the third was western cities and part of middle cities. Thirdly, principle component analysis was taken to get the numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind of cities, then, the differences of numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind was investigated.

然后采用层次聚类分析的方法将282个地级城市分成了3类，采用主成分分析的方法分别对每一类型城市进行分析，得出每类型城市主成分的组数、每组主成分的贡献率及指标的因子值，分析了各类型城市主成分及指标因子值的差异。

On curing, the -NCH〓OH groups of PNMA film would condense with each other to form a network of PNMA in which the PA molecular long chains were be"tightened"in bundles, or be confined in the meshes of the networks. 2. During the developing process of the low-temperature curable, non-formaldehyde PA latices, the monomers were chosen based on the organic/inorganic ratios, and the co-polymerization reactivity ratios. The effects of crosslinking monomer A and B were also compared.

从物质的有机性/无机性值，以及多元单体发生共聚的条件出发，通过比较交联单体A与B的性能，发现采用交联单体A的胶乳的性能良好，确定了一个由软、硬及交联单体A等多种单体组成的混合体系在阴/非离子组成的复合乳化体系中进行乳液聚合制备所要求的低温无甲醛PA胶乳的配方。

Distribution ratios of complex extraction for different operation conditions were forecasted. Using mass action law, the liquid-liquid equilibrium models of complex extraction of monobasic and polybasic carboxylic acid have been successfully induced, and physical extraction were also considered in the model. On the basis of orthogonal experiments, the models of equilibrium distribution ratios were established. The processes of complex extraction were tested and verified. Comparing experimental data with model values, it could be held that the regression precision of model was rather high and the model supplied fundamental data for industrial amplification and practical use of complex extraction.

采用质量作用定律分析方法，成功地推导了同时考虑物理萃取的一元及多元羧酸络合萃取通用液-液平衡数学模型，并在正交试验基础上建立了磷酸三丁酯络合萃取丁酸、三烷基胺（7301）萃取丁酸、丁二酸、柠檬酸的平衡分配系数模型，从平衡角度对络合萃取过程进行了验证与预测，通过实验数据与模型计算值比较，表明模型的拟合精度较好，从而为络合萃取技术的工业放大与实际应用提供了重要依据。

Results Both the area density of stroma and the ratios of stroma to epithelium were the highest in the periurethral zone and the lowest in the supcapsular zone. While the area density of epithelium and glandular lumen in the periurethral zone was significantly lower than those of peripheral zones.The ratios of glandular lumen to epithelium among three zones were not statistically different.

结果 间质面积百分比和间质/上皮比值在尿道周围区、中间区和包膜下区中均依次递减( P ＜0.01)，而上皮和腺腔面积百分比则依次递增( P ＜0.01)；三区间腺腔/上皮比值差异无显著性。
