A tensile facture fractal model of grain filled polymer composites on the base of the fractal theory was established, and an equitation of the tensile fracture fractal dimension was proposed. 基于分形理论构建了颗粒填充高分子复合材料拉伸断口的分形模型,进而提出了分形维数计算公式。
The teaching of equitation and toxophily, which took it as its tenet to uphold the rule of Qing Dynasty, is an important contents in the history of Suolun tribe of the "Eight Banners". 以维护清王朝统治为宗旨的骑射教育,是清代八旗索伦历史活动的重要内容。
Secondly, throttle orifice plate is theoretically analyzed by completely applying relating theory of hydrodynamics and hydrokinetics, and combining kinetics equitation of stickiness flow and confused flow, relation of distances of obtaining press and all parameters. 综合应用流体力学及流体动力学的有关理论,同时结合粘性流动与紊流流动的动力学方程,对节流孔板进行了理论分析,得出了取压间距与各参数间的关系。
A review of concepts, basic equitation and analytic models of two phases fluid. 介绍了两相流的基本概念、两相流的基本方程及解析模型基本方程。
Then make use of multiple linear regression and variance equitation to test price influence factors under tow models and explain the differences of price mechanism between them. 接着,利用多元线性回归和方差方程等技术,检验两种模式下价格影响因素,比较异同,解释价格形成机制差异的原因。
