公路工程水渗流机制的研究还很少，现有的相关研究主要是建立在地表水的疏排、饱和渗流的简单计算、及直观观察经验基础上的防排水设计和施工，没有或很少有根据地下水贮存、渗流与公路工程建设的相互影响，雨水入渗在公路工程结构中渗流规律的研究。

But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.

但是由于纳米粒子表面极强的活性，使它们很容易团聚在一起从而形成带有若干弱连接界面的尺寸较大的团聚体，这大大降低甚至消除了纳米颗粒的实际应用效果，同时由于纳米粒子表面亲水疏油，在有机高分子树脂中难于均匀分散，界面上会出现空隙，当空气中的水分进入空隙中就会触发界面处高聚物的降解、脆化，导致涂层失效。

The dissolubility of PPLA in water was (2.16～4.32)×10－2 mg·mL－1 according to eye judgment. The critical micelle concentration was 2.16×10－2 mg·mL－1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.

目测法得到其溶解度为(2.16～4.32)×10－2 mg·mL－1；荧光法得到聚合物的临界胶束浓度为1.12×10－3 mg·mL－1；透射电子显微镜观察显示该聚合物在水中的自组装聚集体为纳米级球形；动态激光光散射测试微球的粒径和Zeta电位发现，在微球的制备过程中，聚合物的亲/疏水性比例、水相介质及水溶液的pH值对它影响显著；而制备后，稀释和冷冻对它无显著影响，改变微球的环境pH值至酸性，出现聚集，至碱性无影响。

The influences of the concentration and generation of polyamidoamine dendrimer, the ratio of dodecanoic acid to toluene, and pH in the water phase on the extraction yield of helianthine were systematically studied by selecting helianthine as the guest molecule and electrostatic self-assembled PAMAM as the host.

本文采用低支化树枝状大分子聚酰胺胺与月桂酸进行分子自组装得到了一系列具有稠密的疏水性外围和亲水性内核的自组装大分子，再以自组装大分子为宿主，系统地研究了树枝状大分子聚酰胺胺的浓度、支化代、月桂酸与甲苯的质量比及水相pH值对客体分子甲基橙相转移行为的影响规律。

Through thermodynamic calculation and electrochemical analysis of multiple redox reactions on the minerals of galena, sphalerite and pyrite in different system, it could be found that pulp chemical environment in which hydrophobe of collectorless flotation produced was beneficial to reduce collector dosage in existing flotation system; electrochemical analysis on sphalerite had been engaged; and pulp chemical environment of OPF for lead-zinc-iron sulfide minerals and relevant selective measure for collector and modifer were established.

By analysing difference among groups,productivity of Wanxi White goose×Sichuan White goose were estimated.The!results showed that the difference among groups was significant while all geese were divided into 6 groups.The factor scorings of meat power,feather-down power,and eviscerated percentage were higher in group 1 and group 2,which indicated that geese in...

结果表明，当观测个体被分成6组(G1、G2、G3、G4、G5、G6组)时，组间的因子得分具有显著差异；各组产肉力、产毛力和净膛率得分以G1和G2组较高，这些个体的产肉和产毛性能优越，同时具有低脂、肉系水性好、羽绒疏水性强等特点；而脂肪酸品质、产脂力、腿肉率、肌肉水损失、消化力、心功能、绒品质和绒亲水性8个因子得分均以G5和G6组为优，这些个体的脂肪酸品质、羽绒品质以及心胃的辅助性能优越，同时具有腿部肌肉发达，易肥胖，肌肉系水性差等特性。G3和G4则介于两者之间，但其羽型的得分较高。

There is a low-head runoff electric station at lower reaches of principal river and the workshop is the style of riverbed. A successful example of dredging tail water riverbed with the blasting technology in an electric power plant is introduced with the measure of drilling dynamite for enhancing dynamoelectric benefit in the paper.

This network structure restricted water absorption, and kept the tensile strength in wet state and hence increased the water resistance.

而AL在SPI/AL复合材料中对其强度的提高和水敏感性的改善则分别来源于AL的刚性和相对较高的疏水性。
