81.MF transmitter is in normal working order , but HF transmitter is out of order.

中频发射机工作，高频发射机故障。

No electricity, no phone, just HF radios.

没有电力，没有电话，只有高频无线电。

Since 1 mole of H2 and 1 mole of F2, combine to form 2 moles of HF. We can say that the H2 and F2 will each lose 'x' moles per liter while the HF gains 2x moles per liter.

由于 1 摩尔 H2 1 摩尔 F2，结合形成 2 摩尔 HF。 可以说 H2 F2 每升都会损失“x” 摩尔，而 HF 每升增加 2 倍摩尔。

At equilibrium, under these specific conditions the concentration of HF is 2x, or 2 x 0.968, which equals 1.94 molar.

在平衡时，在这些特定条件下， HF 的浓度为 2x，或 2 x 0. 968，等于 1. 94 摩尔。

490. All of our VHF transmitters have failed, now transmitting on HF radio.

490. 所有的甚高频发射机都出现故障，现在用高频无线电发射。

For the HF the total is 2x molar.

对于 HF， 总数是 2 倍摩尔。

The aircraft I fly is B737. It equipped with HF and VHF radio, ARARs, CPDLC, and satellite phone.

驾驶的飞机是 B737。它配备了 HF VHF 无线电、ARAR、CPDLC 卫星电话。

Let's do this for hydrogen fluoride, or HF, an integral part of the process of refining gasoline.

让对氟化氢 (HF) 执行此操作， 它是精炼汽油过程的一个组成部分。

We can say that the H2 and F2 will each lose 'x' moles per liter while the HF gains 2x moles per liter.

可以说 H2 F2 每升都会失去“x” 摩尔，而 HF 每升增加 2 倍摩尔。

No HF has formed yet, so it's initial concentration is 0.

尚未形成 HF， 因此其初始浓度为 0。

Since 1 mole of H2 and 1 mole of F2, combine to form 2 moles of HF.

由于 1 摩尔 H2 1 摩尔 F2， 结合形成 2 摩尔 HF。
