它使土壤温度保持足够的温度，并让微生物保持活跃。
It allows the temperature of the soil to remain warm enough for microbes to remain active.
如果玻璃保持足够的温度，它就会在熔化的锡中流动，直到顶部表面也变得平整、水平，与底部表面完全平行。
If the glass were kept hot enough, it would flow over the molten tin until the top surface was also flat, horizontal and perfectly parallel to the bottom surface.
到目前为止，这场灾难给我们最大的教训可能是，我们手中必须准备足够的紧急电源来保持反应堆水循环的温度，阻止反应堆融化。
So far, the all-important lesson would seem to be: have sufficient emergency power at hand to keep cooling water circulating in the reactors to prevent a meltdown.
这样，足够冷的温度至少在短期内可以使食物保持新鲜。
And this may be cool enough to keep foods fresh at least for a short time.
不同于普通的技术，它能够将蒸馏出的物质保持在足够低的温度，将通常会消失的易挥发材料保留下来。
unlike a regular still, it keeps the distillate at a low enough temperature to retain the volatile components that ordinarily disappear.
盒子里面将比外面空气温度低几度，这些对保持食物新鲜就足够，至少在短时间内。
The inside of the box will stay several degrees cooler than the outside air temperature. And this may be cool enough to keep foods fresh, at least for a short time.
即使加热到正确的温度后，工件也应在此温度下保持足够时间以让其最厚截面达到相同温度。
Even after the correct temperature has been reached, the piece should be held at that temperature for a sufficient period of time to permit its thickest section to attain a uniform temperature.
这些雾气缭绕不散，因为泰坦星地表坑洞中的液态甲烷在为其提供足够原料的同时，也使温度保持在一定水平上，使得空中的甲烷气能够不断受冷液化。
That fog then sticks around because it's in contact with the methane puddles, which keeps everything cool enough to keep the methane condensing.
