[交流] 麻烦高手帮忙翻译一句话

回流法通常是在油浴下加热,如果反应温度过高,时间过长,容易着火,很不安全。还有它的气密性不好,很容易对空气产生污染。

The method of recirculation usually heating up in oil  bath,however,if the reaction temperature is too high or  the reaction time is too long, it catch fire very easily,and this is very degerous.what's more ,the gas tightness of this methed is unsatisfactory, and is prone to contaminate  air.

The method of reflux is usually heated up in oil bath. However, it is very dangerous if the reaction temperature is too high, or the reaction time is too long, and it could catch fire very easily. Furthermore, it is very easy to pollute the air because of the gas leaking in the reactor.

The method of refluxing  often works in oil bath. if the temperature is too high or the reaction time is too long, it is very easy to catch fire. Moreover, it is prone to pollute enviroment due to the poor air impermeability。

花自飘零水自流,一种相思,两处闲愁;此情无计可消除,才下眉头,却上心头
