vacuum case的意思|示意

In the case of constant pipe diameter, lengthening the length of vacuum tube is an effective way to increase the total heat of solar water heater!

在管径恒定的情况下，加长真空管的长度是增加太阳能热水器总得热量的有效途径和方向！

If this is the case, a simple coaxial vacuum feedthrough can be used to make connections from the collector to the picoammeter.

在这种情况下，可以使用简单的真空同轴接头来进行从收集电极到皮安计的连接。

If the electron flow takes place in a vacuum, as in the case of electronic valve, the electrons will travel at considerable speed, since little resistance is offered the medium.

如果电子在真空里流动，比如电子真空管，那么电子的运行速度非常快，因为介质对电子几乎不产生什么阻力。
