In this paper, let R be a left P-V′-ring: we proved the following main results(1) If R is left p-injective, then R is right(left)nonsigular, (2) If R is Left Ap-injective, then R is semiprimtive;(3)Z( RR)∩J(R)=0;(4) If R satisfies the descending chain condition for special left annihilators, then R is left nonsigular.
证明了如下主要结果 :(1)如果R是左P-内射的 ,左P -V′-环 ,则R是右 (左 )非奇异的 ;(2 )如果R是左AP -内射的 ,左P-V′-环 ,则R是半本原环 ;(3)如果R是左P-V′ -环 ,那么Z(RR) ∩J(R) =0 ;(4)如果R是左P-V′-环且R满足特殊左零化子的降链条件 ,则R是左非奇异的 。

In this paper, on the basis of the analysis of the characteristics of wind-blown-sand flow in view of gas-solid two-phase flow, the sand incipience process was realized and observed by using Particle Imaging Velocimeter (PⅣ) technique in a specially designed test facility and the influence factors were discussed.
本文在对风沙流进行气固两相流分析的基础上实现了低风速条件下的沙粒起动过程,借助PⅣ测量系统对其进行了观测并对影响因素进行了分析,获得了沙粒的浓度和速度分布。
