Based on the property delimitation of equity and efficiency,this paper put forward that there is a relation of unity and opposition which evolve in wavelike evolution between them,and make a deep analysis on the critical factors which decide and restrict it.
正确处理公平和效率的关系已成为社会经济发展的重要前提,本文从公平和效率的性质界定入手,提出从历史的角度看,两者之间呈现出一种波浪式演化的对立统一关系,并对决定和制约这一演化规律的临界因素进行了深入分析,在此基础上对我国的公平和效率关系进行了总体界定,认为我国已进入了公平和效率的正相关区间,必须进一步加大公平调节的力度。
In the subcriticality range of 0 1$,the results ofαfrom different position are measured andαc can be extrapolated from theseα values.

This paper measures the critical energy of detonation of hydrocarbon fuel(butane,naphtha,pentene,hexene,JC5) and air mixtures using Bruceton (or up anddown) method in the rectangular shock tube.
该文在矩形激波管内采用布鲁塞顿法(或称升降法)测定了丁烷、石脑油、戊烯、己烯、JC5等碳氢(化合物)燃料与空气混合物形成爆轰时所需的临界起爆能,并根据所测定的临界起爆能的大小,分析比较了这几种碳氢燃料的相对爆轰敏感度及相应的安全性能,最后讨论了分子量,分子中键的饱和度和分子结构等因素对碳氢燃料临界起爆能及相应的安全性能的影响。
