This paper was concerned with the Dirichlet-Neumann mixed boundary value problem of bipolar quantum hydrodynamic model in thermal equilibrium. By truncation method and Leray-Schauder fixed point theorem, the existence of solution to the problem is proved. In addition, the uniqueness of the solution was proved as the Plank constant was large enough.

But ferrous sulfate the by-product of TiO2 cannot be effectively used enough in our country over a long period. In order to solve above questions, the dissertation has done some works as follows:Firstly, the process of purifying by-product of TiO2-ferrous sulfate is studied. The craft and condition of the synthesis of micaceous iron oxide with by-product of TiO2-ferrous sulfate was studied through experiments.

它们都可以通过钛白副产硫酸亚铁为原料制备，但是长期以来，我国硫酸法生产钛白的副产物硫酸亚铁得不到充分有效地利用，针对以上情况，本论文主要作了以下几个方面的工作：首先，研究了钛白副产硫酸亚铁的净化工艺路线，讨论了钛白副产硫酸亚铁水热法合成云母氧化铁的工艺路线和条件，讨论了影响云母氧化铁生成的因素，得出了红、棕、灰云母氧化铁合成的控制条件。

The problems of robust stability and robust stabilization for interval systems were discussed. A necessary and sufficient condition for the robust stability of a line segment polynomial was proposed. The tested results of robust stability of a polynomial polytope and robust stabilization of an interval system were obtained in terms of the condition.
