At the same time, the effect of liquid temperature, the mass flow and the flow direction on cooling effectiveness were obvious too.

同时表明，致冷液温、流量及液流走向，对致冷效能均有显著影响。

For alloy steel piping system, the liquid temperature shall be higher than the brittle transition temperature of the metal material.

如果是合金钢管道系统，液体温度应高于金属材料的脆性转变温度。

So if you had a jar full of triglycerides it would behave like an oil, many would be liquid at room temperature.

所以如果你有一满瓶甘油三酯,它看上去就好像油一样,它们在室温下都是液体

And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.

与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态，气态和固态三相共同达到平衡，三相点是液态。

We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.

为了得到液氦,不能再常温,做这个实验,否则就是加热氦气，因为室温高于它的转变温度,所以焦耳-汤姆孙，实验会加热氦气。

As you may remember from physics class, changing the pressure of a liquid changes its temperature.

Methanol contains 12.6% hydrogen and is a liquid at ambient temperature, enabling it to be used as a means of temporarily "storing" hydrogen until it is needed.

BBC: Hydrogen's energy promise improves

However, by making something out of ions that are bulky and asymmetrical (they have names such as 1-butyl-3-methylimidazolium and hexafluorophosphate, which are as complicated as the ions they represent), the attractive electrical forces can be kept so far apart that the resulting substance is a liquid at room temperature.
