So our usual phase diagram here with temperature on this axis here and pressure on this axis here, and we've got our triple point sitting here.

我们通常的相图是这样，这个轴是温度轴，这个轴是压强轴，这里是三相点。

Then on the y axis, I'm going to plot the total pressure.

我利用y轴表示总压强。

youdao

In operation, the motor structure operates as a linear motor, causing radiating surface 14 to vibrate along a axis of motion 22 (hereinafter "axis"), radiating pressure waves.

在运行中，马达结构作为线性马达工作，使辐射表面14沿着运动轴线22(下文中称为“轴线”)振动，辐射压力波。

youdao

There's pressure on this axis.

用理想气体作为研究对象。
