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。

For a general parametric curve/surface, we usually cannot compute its exact implicit form. Even though its exact implicit form can be computed, the curve/surface implicitization involves relatively complicated computation and the degree is higher. Moreover, it may have unexpected components and self-intersections. All these unsatisfied properties limit the applications of the exact implicitization. So finding curve/surface approximate implicitization has become a practical problem. In this paper, we present an algorithm to solve the approximate implicitization of a given parametric curve by using a quadratic algebraic spline curve.

由于精确隐式化过程不一定可以实现，即使可以实现隐式曲线曲面的阶数高计算复杂，并且具有不希望的自交点和奇异分支，从而限制了隐式化的运用，所以寻求参数曲线曲面的近似隐式化问题成为很实际又重要的问题，提出利用二次代数样条曲线来实现一般平面参数曲线近似隐式化的一种算法。

In this paper,we propose a concept called interval implicitization of rational bézier surfaces,that is ,finding an interval algebraic surface with lower degree which bounds a given parametric rational bézier surface such that some objective function involving the width and the tention term of the interval algebraic surface is minimized.

The action mechanism that (NaPO3)6 depresses almandine is two sides: one is that (NaPO3)6 is chemical adsorbed firmly on the surface of almandine and lead to almandine strong hydrophilic. The other is that (NaPO3)6 selectively dissolves Ca(superscript 2+) on almandine surface and makes the surface cations act with the collector lessening.

NaPO36对石榴石的抑制作用存在两种机理：其一，(NaPO3)6与石榴石表面Fe(上标 2+)发生化学键合导致其牢固吸附而使石榴石表面强烈亲水：其二，(NaPO3)6选择性溶解石榴石表面Ca(上标 2+)导致石榴石与捕收剂作用的表面活性质点减少。

Moreover, it was successfully linked with lactobionic acid through amine groups on the surface of particles, and used to recognize living liver cells successfully.(3) In order to simplify the proceeding of preparation of silica-coated qdots, a novel one-pot method using 3-mercaptopropyl-trimethoxysilane as a capping molecule was proposed for the first time. Furthermore, amine and phosphonate groups were also modified on the surface of silica-coated qdots simultaneously. This was the first time the synthesis and the surface modification of qdots were performed in the same system.
