汉英语境1


英译术语:

naturally-occurring substance


汉语语境:

然而,有机硅材料属于非自然界存在的天然物质,因此,必须寻找合成这类化合物的有效途径和方法。不饱和有机化合物与含Si–H键的硅类化合物在催化剂作用下发生硅氢加成反应是制备有机硅化合物的重要手段,其中以过渡金属催化剂最为有效。


英语语境:

However, silicone materials are not naturally-occurring substances. Thus, the exploration of effective ways of synthesizing such compounds are necessary. Hydrosilylation of unsaturated organic compounds and silicon compounds containing Si─H bond, along with catalysts, is an important means of preparing organosilicon compounds, and the transition metal catalyst is the most effective one.
