( 2 ) the properties of the material with finer andalusite particle size are superior to those of coarse particle size at lower temperature , but properties of material of fine and coarse particle size have little difference at higher temperature . this illustrates that the andalusite particle size can lower the sintering temperature and that it brings forth not remarkable influence on the property of the material when the material is sintered completely ( 2 )对于不同粒度的原料，在烧成温度较低的情况下，粒度小的材料性能明显高于粒度大的材料，但在烧成温度较高的情况下，两者差别不大，说明原料粒度减小能降低制品的烧结温度，但在制品均完全烧结的情况下对材料性能影响不大。
This system model structure not only substantially differentiate the relatively stable and unstable aspects of the business activities , but also explicitly reflect the relationship between them and integrate the information of the system development as well , which is the foundation of the character of dynamic re - configurable for the purpose to support bpr 它分别从宏观和微观的角度，通过对drcmis系统的多种构成要素的建模来完成。这些构成要素包括业务对象类、设计模式、组件、面向对象框架与系统体系结构等不同粒度的可复用系统构建单元的描述模型，以及它们的集成模型。
