This article deals with topics in the critical process involved in the CQFP;such as metallization paste,precision large scale printing, big cavity iso-static pressing,pull strength for fine wire and its future directio.
文中叙述了CQFP陶瓷四边引线扁平外壳工艺研究中的关键工艺技术,如:金属浆料的配制工艺技术、大版精细印刷工艺技术、大腔体层压工艺技术、细引线拉力强度工艺技术等,以及今后努力的方向。
A preliminary investigation on the axial initiating power of blasting caps including the electric, the non-electric and the nonel tube detonators is made by reference to the Standards of International Study Group for the Standardization of the Methods of Testing Explosives(EXTEST) and our experience.
本文参照“国际炸药测试方法标准化研究组织”(简称EXTEST)公布的非电和电雷管引爆强度试验资料,结合中国的实际情况,对工业雷管(工业火雷管、工业电雷管、导爆管雷管)轴向引爆强度的测定方法作了初步的研究。
Base on the Site-Level demand forecasting method,this study emphasize on the attractive intensity in this area,get the result of the relationship between the attractive intensity and the distance.
建设停车换乘(P&R)设施已经成为解决大城市交通拥堵的途径之一,基于具体地点的需求预测方法,从P&R设施影响范围的确定方法出发,在已有研究的基础上,进一步对这一影响范围内的吸引强度进行了研究,得出了换乘吸引强度与距离之间的相互关系,并对影响吸引强度的因素进行了分析。
This paper proposed the concept of the intensity of citation.
本文提出了引证强度概念,在考虑了学术论文所在期刊学术影响力的前提下,考虑论文被他引次数在该论文质量量化中的正面效应,同时考虑"故意自引"有可能带来的引证强度放大的负面影响。
