时相图

时相图特点分类研究及其临床意义

Classified study and clinical value of the phase imaging features

利用这些结果可以清楚地描述这类方程当参数变化时相图的变化情况。

So the phase portrait can be clearly depicted as the parameter changes .

在优化Al合金成分以及在热处理过程中了解温度、时间和成分对材料性质的影响时，相图热力学和扩散动力学发挥着至关重要的作用。

Knowledge of both thermodynamic and diffusion kinetic characteristics of Al-based alloys is of critical importance in optimizing alloy composition and understanding how temperature , time and compositions affect the microstructure during heat treatment .

熔化极等离子弧焊接电流增大时，U-I相图的线簇随着电流增大而集中，熔滴过渡依次为短路过渡、大滴过渡和射流过渡。

With increasing of MIG weding current the cluster of closed lines in the U-I phase graph are more concentrative and the transfer mode of droplet is short circuiting transfer , globular transfer and spray transfer in turn .

四极滤质器中离子运动方程的近似解法及100%传输时的接受相图

The approximate solution of the equation of motion and the general diagram of acceptance for 100 % ion transmission in QMF

应用有限差分法求解球壳振动的振幅和外加荷载之间的微分关系，得到了球壳振动的时程和相图。

The time history curves and the phase diagram for the oscillation are obtained by solving the differential relation between vibration amplitude and tensile load with finite difference method .

应用杠杆定律时，必须遵循相图的基本规律并使用标准术语。

While using lever rule , the fundamental law of phase diagram and use of standard terminology must be followed .
