THE TENSILE STRENGTH OF WATER IN DEPRESSION TANK

This paper presents the data of tensile strength of water in depression tank whichwere measured by small venturi during cavitation investigation of a series of real project models.These measurements show that in depression tank water has slight tensile strength in case of highvacuum.But it influences the incipient cavitation number.In tests we also studied the influenceof tensile strength on scale effect of cavitation models.     

EXPERIMENTAL RESEARCH ON EFFECT OF MAIN-FLOW SWING ON FLOW TURBULENCE STRUCTURE

It is mentioned in this paper that the adjustment of flow structure occurs when themain-flow swings.The changes of turbulence structure and flow energy loss in the indoor rivermodel are measured.The experimental data are presented for the first time for the further studyof complicated river flow structure.     

NUMERICAL STUDY ON SORET-EFFECT AND DUFOUR-EFFECT FOR DOUBLE-DIFFUSIVE NATURAL CONVECTION IN POROUS ENCLOSURE

The influences of Soret effect and Dufour effect on the natural convection and heat and mass transfer for a porous enclosure were investigated by means of the penalty finite element method. Numerical results indicate that the Soret and Dufour effects have significant influences on heat and mass transfer in the presence of large temperature gradient and concentration gradient.

澳大利亚水库淤积问题

水库淤积已经成为澳大利亚的一个严重问题,介绍了澳大利亚的水库快速淤积和极端淤积的几个实例,分析了水库完全淤死的原因。大坝和水库应该以冲沙的形式进行系统的管理,在干旱期必须加强流域的水土保持措施。     

人才测评九步法

人才测评选择、实施的主要程序如下:1.进行工作分析工作分析是将一项工作分解为对于工作业绩至关重要的各种不同的活动 以确定出人才测评应该预测的领域。2.选择一项专业的人才测评一项良好的人才测评应该准确、一致地对那些对工作成功至关重要的知识、技术、能力和态度进行衡
