“top down”和“bottom up”——评我国纳米科技发展的导向问题

"top down"and"bottom up"

纳米科技有"top down"和"bottom up"两种研究方法,这两种研究方法中"top down"方法是今后一个时期的主要科研方法,但是决不能忽略甚至放弃"bottom up"方法的探索和研究,因为"bottom up"方法代表着纳米科技发展的未来。这是对我国纳米科技发展策略的挑战。

There exist top down and bottom up approaches in the research and development of nano-science and technology.Although the top down approach is viewed as the principle method of the research in a given period of time,for the reason that the development of bottom up approach represents the future of the development of nano-sci- ence and technology,the research on bottom up approach should not be ignored.It is a challenge to the strategy of the development of the nano-science and technology.
