But sulphur conducts heat very badly.

但是硫磺的导性却很。

Wood also has low thermal conductivity, making it easier to heat and cool buildings with less energy waste.

木材还具有低导性，使其更容易为建筑物供暖和制冷，减少能源浪费。

Professor Daniel Nicodemo credits silk's price tag to its thermal conductivity and sturdiness.

Daniel Nicodemo 教授将丝绸的价格标签归功于其导性和坚固性。

From this we see that lunar  regolith is a really poor heat conductor.

由此我们可以看出，月球的导性非。

Aluminium, being a metal, readily conducts heat.

【conduct】铝这种金属导性能很好。

The second is to choose a thermoelectric material which conducts heat badly (so that different parts remain at different temperatures) but electricity well.

第二是选择的电材料的导性（这样不同部分就能保持不同的温度）但是导电性良好。

The third is to be certain that the temperature gradient which that badly conducting material creates is not frittered away by poor design.

第三是确保那种导性的材料产生的温度变率不因为设计缺陷而白白浪费。

For Oumuamua, these temperatures can be reached between 50 and 250 centimeter below the surface, provided the rock has a low conductivity profile.

对于奥陌陌而言，在岩石导性较低的情况下，这些温度可以在表面下50到250厘米处达到。

It's 200 times stronger than steel by weight, lighter than paper, it's super-flexible and the most conductive material of both electricity and heat ever discovered.

按重量计算，它的强度是钢的 200 倍，比纸还轻，它具有超强的柔韧性，是迄今发现的导电性和导性最好的材料。

And as you may have guessed, diamond conducts heat even better than graphite because each atom spreads that energy in three directions rather than two.

正如你可能猜到的， 钻石导性能甚至比石墨更好，因为每个原子会将能量向三个方向扩散， 而不是两个方向。

78. Question: How can we improve the thermal conductivity of a PCB in PCBA? Answer: By using materials with high thermal conductivity, adding thermal vias, or incorporating heat - spreaders.

78. 问题：我们如何提高 PCBA 中 PCB 的导系数？答案： 通过使用具有高导性的材料、添加通孔或加入散器。
