1·Along this red path, you start with an isobaric process and end with an isothermal process.
沿着这条红色路径，你从一个等压过程开始，以一个等温过程结束。
2·So this is an isothermal expansion.
这是个等温膨胀过程。
3·So from one to two it's isothermal.
从一点到二点是等温过程。
4·This is isothermal. This is adiabatic, there's no heat.
一个是等温，一个是绝热。
5·So here's path a, it's isothermal.
那么这是路径a，它是等温的。
1·If I want to compare it with the isothermal expansion, which is sitting here.
我们要将它与，这幅图中的等温线相比较。
2·We calculate the temperature distribution of rectangle base caused by two circular heat sources isothermal lines and three dimension figure were given.
具体计算了矩形基板内布置两个圆形热源时，基板的温度分布，并绘制了等温线及立体图。
3·Control of the penetration and width of the back side weld was then achieved by controlling the width of an isothermal line near the melting point.
通过控制接近熔点温度的等温线宽度最终实现了对焊缝背面熔宽和熔透的控制。
