Obtaining a phase diagram of a matter , the relationships between the matter ’ s components , structure and capabilities can be easily got , which is just the place where phase diagram study shows very important meaning 获得了某种材料的相图，就很容易探索和了解该材料的组分、结构和性能之间关系的规律，这就是相图研究的意义所在。
Abstract : the phase photograph of a simple pendulum is discussed . two methods of calculating the nonlinear pendulum period is given with the phase orbital properties and the action variation 文摘:对单摆运动相图作了必要的讨论，赋予相图以直观的几何意义，并由单摆相点运动特性以及引入单摆系统作用变量两种方法求出了单摆系统的运动周期
Results of simulation prove the significance of the pore size distribution in drying of porous media . in addition to drying simulation , a two - dimensional transparent porous media experimental model is set up 通过比较不同大小、不同分布的孔道网络模拟干燥相图不难发现，孔道尺寸及其分布对干燥过程中液体团的形成及发展有着重要影响。
Given a group of the attractive interactions " values , the isothermal sectional diagrams and the vertical sectional diagrams of the typical phase diagram of the ternary system ( e . g . the “ even crystal ” type ) are obtained 液两相平衡曲线方程的表达式，给定势参数后，得到了典型的三元系统固液相图（如，匀晶相图）的水平截面图和竖直截面图。
