Based on the theory of shrinkage, capillary force theory, the influence of road concrete additives in common use on surface tension of water is studied, and the results show that the influence of water reducer is very small whereas shrinkage-reducing agent and air entrainer can reduce surface tension of solution significantly. The relation between surface tension and additive dosage are non-linear relation. Each additive has an obvious critical micelle concentration.

从混凝土收缩的基本理论——毛细管张力理论出发，通过道路混凝土外加剂对水的表面张力的影响研究发现，减水剂对水的表面张力的影响很小，而减缩剂和引气剂可以大幅度降低溶液的表面张力，溶液的表面张力随外加剂的掺量呈非线性形式降低，而且都存在临界胶束浓度。

The results show that for a supersonic shear layer without reaction, a disturbance can make the shear layer become unstable, this results in one vortex or more than one vortex. The combination and seperation of vortex can intensify the mixing. But it is not easy for supersonic reacting shear layer with exotherm to become unstable with disturbance, and the effect duration is very long.

结果表明，对完全气体的超声速剪切层流动，一定的激励方式能使原先较为稳定的剪切层流动变得不稳定，产生单涡或多涡结构，发生多涡间的合并，使混合加剧；但对于存在放热现象的反应超声速剪切层流动，外加激励方式不易使流动从稳定变为不稳定，而且外加扰动的作用特征时间也较长，实际应用前景不乐观。

The experiment result show that desulfurization efficiency declined with the increase of flue gas flux and SO_2 inlet concentration; desulfurization efficiency added with the enhance of Ca/S molar ratio, flue gas humidity, the moisture content of calcium sorbent, desulfurization efficiency also increased after adding activated vapor, superinducing additive, inflicting applied voltage.

With the existence of additional carbon sources, sodium lactate, sodium propionate or sodium acetate, the faster pH rised, the faster p, p'-DDT dechlorinated, which indicate that the existence of short chain organic substrate supplies sufficient electron donors for the dechlorination process, and p, p'-DDT can obtain electrons more easily during the stage of pH rising.

并且由于p，p'-DDT的还原脱氯与细胞色素氧化酶及辅基FAD有关，外加碳源下p，p'-DDT的缺氧降解多数发生在体系pH值上升的阶段，且pH值上升较快时对应的p，p'-DDT缺氧降解较快，而在无外加碳源的体系中，由于可供p，p'-DDT还原脱氯的电子量限制了p，p'-DDT还原脱氯的速度，未发现上述现象。

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.
