whose代表什么?《石油化工英语文选》之一? coke formation is due to olefinic and diolefinic compounds whose formation will be influenced unfavourably by a decrease in temperature, an increase in pressure and ratio h2/hc. 这里面最终要说明的是结焦的原因和如何减少结焦,所以我觉得whose到底修饰什么并不是最主要的,哪怕认为是修饰olefinic and diolefinic compounds ,最后还是要归结到coke上去 从减少结焦的措施看:降低温度、增加压力或增加氢烃比都应该是减少烯烃和双烯烃结焦的具体手段,前两者很好理解,后面的增加氢烃比感觉可以使烯烃加氢从而变成饱和烷烃,降低烯烃和双烯烃的含量查看更多
