The phonon Green function of staff made with monatomic simple cubic crystal in nano machine and micro machine is deduced with Dyson equation in this article.

Based on database of CA ON CD in 18 years from 1987 to 2004,the authors try to statistically analyze literature on nanometer science and technology,with respect to metering and predicting general status of nanometer science and technology,progress in different countries,hot-point in nanometer R&D,and situation at applied technology development.

In order to obtain sustainable development, we analyze and think the nanometer science and technology in china.

This paper talks about the application research situation on nanometer science and technology and nanometer materials in the fields of magnetism,electron,optics,catalysis,sensitiveness,and biomedicine and so on,showing the direction for further research.
