变质量
运用变质量系统的基本原理,建立轴流脱粒过程中谷物运动的非线性动力学模型。
Based on the principle of the varied mass system, the no-linear mathematical model of the crop mechanics in the axial threshing space has been set up.运用变质量系统的基本原理,建立轴流脱粒空间内谷物运动的非线性力学模型。
The formation of roll-casting microstructure is mainly attributed to the deformation of un-solidified liquid phase, the varied distribution of mass and heat.铸轧组织的形成主要是变形作用于未凝固的液相,引起质量和热量的分布状态发生改变所致。
