The packaging of micro electro mechanical systems (MEMS) is referred to first-level packaging and limited generally to the preservation of wafer in this paper. It is based on bulk silicon bonding technology and film sealed technology. The bulk silicon bonding technology includes electrostatic bonding, silicon direct bonding and interfacial layer assisted bonding. It is used for making material acting as substrate or cover of the chip. The film sealed technology includes whole-wafer operation, local-wafer operation and selective preservation. It is used to seal micro channel or micro hole to form a vacuum or low-pressure cavity or protect from atmosphere influence. The very high importance not to forget packaging at the beginning of a project, when hoping to industrialize MEMS is discussed. In order to obtain high performance-price ratio,it is necessary to weigh the device performance against the chip complexity. The commercialized pressure sensors, accelerometers, digital micro mirror devices, etc., collected from literatures are used as examples.

Strategic Study of CAE 2000, Volume 2, Issue 3, Pages 62-66
Measurement is an important means for obtaining information in research and production. Both the quality of products and the productivity of production highly depend on measurement. An important trend in the development of measurement is its merging with information technology. The requirements in high accuracy of measurement, on-line and dynamic measurements, measurements of complicated parameters and under complex conditions and intelligent measurements ask for the merging of measurements with information technology. This merging is carried out through the whole process. Modulation and demodulation, data sampling and reconstruction, signal merging, data compression, filtering, signal transformation, time series analysis, spectrum analysis, data fitting and modeling, pattern recognition, neural network, simulation and virtual measurement, error separation, error compensation, redundancy technique, decision making, intelligent techniques, etc. , are widely used in measurements. Some practical examples of this merging are given in the paper. The accuracy of coordinate measuring machines (CMMs) can be greatly enhanced by using error compensation technique. Modeling, error calibration and compensation software are three key techniques in error compensation of CMMs. Applications of redundancy technique in roundness and spindle error motion measurement, in large scale metrology are presented as well. Redundancy technique provides a powerful means in optimization of measurements, system self-calibration, error compensation, recovering the lost information and many other applications.

The Delphi method is the most common method of technology foresight, which is a significant basis for establishing development strategies and policies of science and technology. This study proposes 45 alternative technologies in the field of environmental engineering science and technology through a literature survey, experts' advice, and discussion meetings. These technologies relate to air pollution prevention and control; water pollution prevention and control; soil pollution prevention and control; solid waste pollution prevention, control, and utilization; ecological protection and restoration; environmental monitoring, early warning, and risk control; resource utilization and cleaner production. Based on results that were obtained according to the Delphi method, this research analyzes the realization time, R&D level, and restriction factors for the key technologies, common technologies, and disruptive technologies that were determined for 2035. This study provides a reference for establishing development strategies and objectives for China’s environmental engineering science and technology over the next 20 years.

The knowledge chain of science-technology-engineering-industry is studied in this paper based on their essences and meanings. It is pointed out that the connection of technology and engineering with economy is much tighter than that of science with economy. It is stressed that science-fundamental research is the transformation of capital to knowledge, and that the technology innovation is the transformation of knowledge to benefit and profit through market by the support of capital. Engineers are the important creators of new productive force and active pioneer of new industrial field. Engineers will confront with technology innovation at different levels, in different areas and on different scales. Much more attention must be paid to the creative work of engineers, especially in rapid economic growth period. The cultivation of a large number of qualified personnel in technology engineering is the requirement for promoting economic development and social progress.
