Now science popularization in China is in the course of transition, which is quite different from the traditional one. We should make a good study of it because: first, great changes have taken place and are taking place during this period; second, the transition is just like the neck of a bottle where blocks may appear; third, our country in quick development provides more opportunities and better conditions for the transition of science popularization. To realize the transition in science popularization, we should pay more attention to the following: 1. As for the content of science popularization, it should contain all meanings of science, including scientific knowledge, scientific thoughts, scientific methods and scientific spirit. 2. Set up three new mechanisms for science popularization in China. They are: more input, better working mechanism and more qualified scientists and technicians for science popularization. 3. Set up evaluation mechanism for science popularization, promote researches on quality measure.
