The heat and the chemicals used to separate metal from dirt or hazardous can make workers sick but for many who pan the streets for gold, a steady source of income is often more important than their health.

高温和用于将金属与污垢或有害物质分离的化学物质会让工人病，但对许多在大金的人来说，稳定的收入来源往往比他们的健康更重要。

Miller said, " Heat is one of the greatest risks that we have in this work, even though we deal with high radiation, hazardous chemicals and heavy metals."

“尽管我们处理的是高辐射、危险化学品和重金属，但高温是我们在这项工作中面临的最大风险之一。”

Basically, the heat causes the lipids in the oil to break down and produce some volatile compounds, which are chemicals that can easily become gases.

基本，高温会使得油中的脂类分解，并成更易挥的合成物，而这些合成物是易变成气体的化学物质。

There are a number of methods of preserving food which involve both high and low temperatures, chemicals, irradiation, and drying.

保存食物的方法有很多，包括高温和低温处理、化学方法、辐照以及干燥等。

CVD gives scientists more specific control than high pressure high temperature reactors, but the growth rates are much slower.

与高温高压法相比，化学气相沉积法让科学家能进行更精确的控制，但度要慢得多。

His design uses ceramics that can also withstand high temperatures, do not corrode and do not react with tin.

他的设计还将陶瓷加入，这种材料能够耐高温, 不易腐蚀, 而且不会与锡化学反应。

By using a few chemicals, heat and pressure, they have made wood three times denser and 10 times stronger.

通过利用一些化学物质、高温和强压，他们使木材的密度提高了3倍，强度也提高了10倍。

And at 5000 degrees we reach the temperature inside the initial blast of a conventional chemical bomb.

在 5000 度的高温下，我们达到了常规化学炸弹初始爆炸时的温度。

We still don't know how the ancient Egyptians originally figured this recipe out, but the chemical reaction would have required careful control of this super hot temperature and the flow of oxygen into a furnace.

我们仍不知道古埃及人最初是如何得到这个配方的，但化学反应对这种特高温以及火炉中的氧流量有着谨慎的要求。

Scientific evidence suggests that the majority of stars within these globular clusters were formed through a process involving the mixing of gas with hot hydrogen and other chemical elements expelled by the explosive deaths of short-lived older stars.

科学证据表明，这些球状星团中的大多数恒星是通过一个过程形成的，该过程中气体与高温氢及其他化学元素混合，而这些元素是由短寿的老年恒星爆炸性死亡时释放出来的。

Making electricity or probably more advanced, like what we might see more of in the future as well, is making high temperature heat for chemical processes for making hydrogen or making plastics and chemicals, that kind of thing.

产电力或者更进一步，比如我们未来可能会看到更多的是，利用高温热能进行化学过程，如制造氢气或塑料和化学品等。

And they use these technological processes, high pressure, high temperature processes that result in diamonds with identical chemical, physical, and optical characteristics as natural diamonds.

他们使用这些技术工艺，即高压高温过程，产出的钻石在化学、物理和光学特性都与天然钻石完全相同。

After 27 years of excessive heat and harsh chemicals, my hair was beginning to show extreme signs of wear and tear.

经过 27 年的高温和刺激性化学品，我的头开始出现极度磨损的迹象。
