Then the algorithm was used to get the seven parameters of viscosity model of W-Ni-Fe heavy alloy and 316L stainless steel feedstock, which provide the necessary material data for quality forecast of mold core part made of stainless steel and heavy alloy tungsten ball, and for optimal design of mold and process parameters, which establishes the foundation of material database of MIM. In the research of visual simulation software development, in order to build the software system model and flow analysis algorithm based on Cross-WLF viscosity model, and realize functions such as pre-processor, solver, parameter regress, data management, graph operations, some advanced software methods as OOSE (Object Oriented Software Engineering) and UML were applied to set up user model, static model and dynamic model of MIM simulation software. These models describe system function, event flow, structure and relation of classes, object interaction, structure of database and I/O file format.

在MIM可视化仿真软件开发方面，为了建立软件系统模型及基于Cross-WLF粘度模型的流动分析算法，实现软件的前处理、求解器、参数拟合、数据管理和图形操作等功能，将面向对象软件工程与统一建模语言技术首次引入到MIM仿真软件的设计开发中，建立了软件的用户模型、静态模型和动态模型，描述了系统的功能需求、事件流程、类的结构与关系、对象之间的通信、数据库结构和输入输出文件格式等，用Visual C++与Delphi开发工具编码实现了2维MIM充模流动过程仿真软件，方便了对薄壁零件的质量预测以及模具和工艺参数的优化设计。

It should be noted that not only in the complex perovskite like BaO3,(X=Mg, Zn, Co, Ni, Mn: Y=Nb, Ta) but also in the compounds with tungsten bronze structure such as Ba6-3xLn8+2XTi18O54, they are consisted of corner-sharing oxygen octahedra and the ratios of ion in B site to ion in A site are usually larger than one.

值得注意的是业已开发出来的材料不论是复合钙钛矿BaO_3，(X=Mg，Zn，Co，Ni，Mn；Y=Nb，Ta)还是钨青铜结构，它们都是由氧八面体共顶连接，而且氧八面体内、外阳离子比例都等于或略大于1，因此，我们推测在B位与A位阳离子比例略小于1的类钙钛矿结构中极有可能存在具有优良介电性能的新材料。

A yellow or yellowish-green mineral, essentially WO3, often occurring with tungsten ores.

钨华一种黄色或黄绿色的矿物。主要是WO3，通常存在钨矿石中
