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。

There are series of papers studying the solvability of an incompressible, viscous, instationary fluid contained in a domian bounded entirely by a free surface. In 1977, Solonnikov proved its local solvability in a Holder space for any initial date but without surface tension. In 1984, he considered the same problem in a Sobolev space with surface tension being taken into account. In I992, Mogilevskii and Solonnikov treated the same problem in a Holder space, where the coefficient of surface tension is not a constant. There are also short-time existence results for the solvability of an incompressible, vicous, unsteady fluid bounded above by a free surface and below by a fixed bottom which approach horizontal planes at infinity. In 1981, Beale proved its local solvability in a Sobolev space for any initial date but without surface tension. In 1983, Allain were concerned with the same problem in R〓 with surface tension but under the assumption that the initial fluid domain was near a horizontal strip. In 1987, he obtained the same result without the preceding assumption. In 1996, Tani solved the same problem in R with surface tension. For the solvability of an incompressible viscous instationary fluid in Ω R bounded inside by a free surface S and outside by a rotating boundary S, in 1995 Ciuperca proved its local existence in a Sobolev space for any initial date but without surface tension. In this paper, we consider the same problem with surface tension.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH
4、25℃,N_xB系列都有较低的表面张力,并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN/m低,且临界胶束浓度为4.1×10~(-5)mol/L,也比LAS低,且随着NaCl浓度的增加而略有下降,比较N_(12)B和N_(16)B,由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低,由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。

Interfacial tension:表面张力
邻域内Cd、S与Cd、Cd的距离分别小于体材料值的0.2%,并且最大表面张力(interfacial tension)为0.15 N/m. 如此低的表面张力表明镶嵌在玻璃中的纳米粒子比同尺寸裸露的或被包埋的纳米粒子更为稳定. 发光二极管在信息处理、光通讯及其它光电子领域有着广泛而重要的应用价值.
