By analyzing the characteristics of high & new technology superior enterprises and the influential factors, the evaluation index and method based on Grey Relation Analysis are designed. Some high & new technology enterprises in Heilongjiang province are evaluated and application tactics of evaluation system are proposed. This study provides scientific method and basis for government to obtain development state about high & new technology enterprises and design planning and policies of high & new technology industry.展开更多

However, no reliable theoretical guidance has come into existence, which greatly restricted the application of CAD（ Computer-aided design）. In order to feed the application of CAD technology, we must make improvements to the existing coding method. Based on the similarity principle of Group Technology and existing coding system, a new coding method applicable to slide- way design is brought forward. The existing coding system could get optimized by means of analysing and studying the influence imposed by the parts＇ shape and posture features. More detailed information about the parts could be supplied by the new coding system, which makes the design simpler, more convenient and more accurate with the subjoin of the initial and targeted codes.展开更多
