Abstract: Abstract: In daily life, due to scientific uncertainty and the limitations of self cognition, the general public is usually through common sense rather than scientific knowledge itself to judge the risk of modern science. Specifically, they doubt the scientific risk through three angles : government regulation , technology ethics, and benefit from. But there is dislocation between China's science and technology communication and public risk perception. Our mainstream media should undertake their risk communication function: lead multi angle, all-round coverage of scientific issues report, guide the extensive and in-depth discussions in society, so as to promote the public to reach a point of view that is relatively rational and mature.
