天津理工大学 Scientific English Writing EST Contents Introduction to Scientific English Science writing in our country, according to many experts in English is， in fact， scientific translation from Chinese to English. That is to say, all Chinese students are able to write academic papers in Chinese. The problem is how they can put their papers into English. Quite a few professors and graduate students in our country sent their papers to the well-known technical journals abroad, such as the American IEEE and the British IEE. The reviewers comment may often be like this: What you described in the paper is O.K., but your English is poor. Please improve it( Or Please rewrite your paper entirely.)

Common examples are silicon and germanium. Semiconductors are quite sensitive to heat and light, both of which have a great effect on their conductivity. Therefore/Thus/So/As a result, semiconductors are widely used for a
