The Wielandt inequality is an improvement on the general Cauchy-Schwarz inequality, and its applications to statistics were studied. In a note, Wang and Ip (1999) gave the Wielandt inequality in matrix version in terms of the Lo|¨wner partial ordering.

Wielandt不等式是对著名的Cauchy-Schwarz不等式的一种改进，该不等式被广泛应用于统计理论中线型模型的研究方面，因此研究更一般形式的Wielandt不等式有重要的意义。

Vector derivative ; matrix ; the plane complex movement of a particle

In order to solve the problem that matrix A often occurs irreversible when shape function is calculated by using traditional element free Galerkin method, the orthogonal function with the weight function is utilized in the paper. And partition of unity quadrature technique is employed and so a truly "meshless" method is realized.

针对传统无网格伽辽金方法在构造形函数时，矩阵A容易出现不可逆的弊端，采用带权正交基函数构造形函数，在积分方案上采用单位分解积分方法，从而实现了真正的"无网格"。

The relationship between physico-chemical properties of nano-CaCO〓 and surface treating technology was studied. The results showed the coating model of micron CaCO〓 was not suitable to nano-CaCO〓. The influence of dosage of treatment agent on nano-CaCO〓 dispersion degree in matrix was studied, the results indicated it only need to passivate some active zone on nano-CaCO〓 surface.

研究结果表明，微米粒子的表面包覆活化理论不适宜用来指导纳米粒子的表面处理，在对纳米碳酸钙进行表面处理时，不需要在纳米碳酸钙表面形成完整的包覆层，只需对纳米粒子表面的部分活性点进行钝化即可，即纳米碳酸钙表面有限钝化。
