Basic distillation involves application of heat to a liquid mixture, vaporization of part of the mixture, and removal of the heat from the vaporized portion. The resultant condensed liquid, the distillate, is richer in the more volatile components and the residual unvaporized bottoms are richer in the less volatile com-ponents. Most commercial distillations involve some form of multiple staging in order to obtain a greater enrichment than is possible by a single vaporization and condensation. For ease of presentation and understanding, the initial discussion of distillation processes involves binary systems. Examining the binary boiling point (Fig. 1a) and phase (Fig. 1b) diagrams, the enrichment from liquid compositionxL to vapor composition yL represents a theoretical step, or equilibrium stage.求翻译稍微专业点哈

一段化工专业英语~有人帮我翻译一下吗?
第一句就翻译错了。The pressure changes the gas solubility; 一个翻译成:“压力气体的溶解度变化”, 另外一个翻译成“气体的溶解度的压力变化”,明显是在乱翻译嘛,都没理清句子的结构和含义。这一句是表达:双氧水(过氧化氢)的合成,受到压力的影响,压力能改变气体的溶解度。
