结果表明：一定条件下聚合物凝胶和疏水缔造合聚合物溶液具有相似的溶液结构和流动特性；胶态分散凝胶在多孔介质中的流动存在转变压力，2组流动实验中疏水缔合聚合物溶液也表现出类似的转变压力，分析认为聚合物凝胶分子链间的联结是化学交联，而疏水缔合聚合物为物理缔合，类似的分子链间联结方式是两种体系有相似流动特性的内在原因。

The costs of inbreeding When closely related individuals interbreed,'inbreeding' occurs ,which gives rise to inbreeding depression (which causes a reduction in offspring fitness) and increased genetic homozygosity (which reduces the possibility of evolutionary adaptation to a changing environment, and increases the possibility of extinction).

近交的代价当亲缘相近的个体进行亲繁殖时，"交近"就出现了。近交引起近交衰退和增加遗传纯合性(它降低了对于环境变化产生进化适应的可能性，而增加了灭绝的可能性)。

NBR/modified montmorillonite and NR/HMMT nanocomposites were prepared by the mixing intercalation method with the monomers resorcin and hexamethylenetetramine complex . XRD and TEM showed that the interlayer spacing of HMMT had got much larger with RH addition and the layers of HMMT had dispersed in rubber matrix on nanometers. FTIR and crosslinking density results explained that chemical reaction had occurred between RH and rubber in the course of vulcanization, which improved the crosslinking density of rubber and enhanced the interaction between the rubber and HMMT.

采用单体混炼插层法，引入间苯二酚-六次甲基四胺的络合物，制备了橡胶／改性蒙脱土插层纳米复合材料。X-射线衍射分析表明：RH的加入使蒙脱土层间距不断扩大；TEM观察到无机片层在橡胶基体中纳米级分散；FTIR和交联密度的分析发现，在硫化过程中RH与橡胶发生化学键合反应，同时与改性蒙脱土相互作用，使得体系交联密度提高。

In this study, an OsNPR1 rice over-expression vector was constructed and transformed into rice cultivar TP309 and 17 homozygous lines were obtained by self-fertilization and selection. The genetic stability of introduced OsNPR1 in the T3, T4 progenies of homozygous lines was confirmed by PCR. When the transgenic plants were challenged with bacterial blight pathogen Xanthomonas oryzae pv.

MethodsWith the package rate of volatile oil as the evaluating indicator, the method of saturated water solution,trituration method,and ultrasound method were compared. Orthogonal design was used to select the best packed preparation condition of the best packed method,and the packed substance was detected with TLC.

方法以挥发油包合率为评价指标，对饱和水溶液法、研磨法及超声法进行了比较实验，采用正交实验法对优选出的包合方法的最佳包合工艺条件进行考察，并对包合物进行TLC检验。

Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

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.

Computer simulation indicates that each item of POAS represents only a specific frequency range.

通过计算机仿真，发现正交多项式中每一项都基本上只代表特定的空间频率范围，根据相位度量的环扇形镜面面形空间频率分布，选择适当的正交多项式的项进行拟合，不仅能够节省运算时间，而且还可以保证拟合精度。

According literature above,its considerd that the former is proper to be interpreted by means of multiple alleles hypothesis,and the fertility heredity of the latter is appropriate to be interpreted using inhibition.

根据大白菜及其近缘芸薹属作物核不育材料育成的纯合两型系和杂合两型系可育株间互交F~1|可育株自交，其子代可能出现无育性分离情况或者产生13∶3两种表型的育性比资料，认为前者宜用复等位基因假说解释，而后者用抑制作用解释为妥。
