This resulting composite is extremely hard and heat resistant.

结果就是使混合物极其稳定而且耐热。

Heat resistant glass was invented in Germany at the end of the 19th century, but was used mostly in lanterns and in jars to hold telegraph and telephone batteries.

耐热玻璃是19世纪末在德国发明的，但当时主要用于灯笼和盛电报、电话电池的罐子。

Not impossible to infect, just harder. And  the heat resistant microbes now compete with their cousins that like it colder  and have an advantage infecting healthy hosts. This creates an evolutionary  dilemma without a perfect solution.

不是不可能感染， 只是更难。 耐热微生物现在与它们的竞争，喜欢更冷， 并且在感染健康宿主方面具有优势。造成了一没有完美解决方案的进化困境。
