摘要:This paper presents a generalized Weber-Feehner's Law.It shows that this law can be used in assessing lighting,acoustical andthermal environment of building.The room articulation funetion,the li-ghting clarity funtion and the thermal comfort function are derived fromthis law.The ealeulated results of these funetions are coincident withthe experimental data obtained by some famous researchers in the world.It can be thought to be a universal law.
摘要:Based on the contributing factors of earthqutake,its hazardregularity and the site investigation at Tongjing town in Chongqing,thispaper presents suggestions on the basis,principle and aim of earthquakeplanning in mountainous region,cities and towns as well as site selection,general layout of city,building arrangement,road width and quakeproofsafe area establishment,etc,
摘要:In this paper,the ring shell lining with annularly verticalwalls made contact with the surrounding rock is considered as a combinationstructure formed of ring shell,inner and outer annular barrels on elastic fo-undation.The complex equation and its solutions of ring shell under deadload of lining and vertical and horizontal surrounding rock pressures are de-rived by the method of complex function.The governing equation and itssolution of the barrels on elastic foundation are also derived by theory ofcylindrical shell.And then,the ring shell lining is assembled by the subst-ructures by means of compatibility conditions of internal forces and defor-mations between them.In the paper,all formulas for the practical computa-tion in engineering are derived,the numerical examples are given and theeffects of the parameters of the lining on the work behaviours of lining alsoare discussed preliminarily
摘要:Based on general concepts of microcomputer developmentsystem,the design concept and main characteristics of 1802 microcomputerdevelopment system are introduced in this paper.This system is ratio-nally designed,powerful in function and very useful for further develo-pment and application of 1802 host computer in communication.
摘要:In this paper,the strength properties of rock mass withrows of intermittent bidirectional cross joints by simulating models arediscussed.Work has been done on finding the failure mechanism of therock mass as well as the influence of joint direction and lateral pressureon tne strength of the rock mass.At the end of the paper,model testresults ahd FEM analyses are presented and strength criteria for thiskind of rock mass are proposed.
摘要:McHarg,a noted American landscape architect,hasbecome well known around the world as one of first group of ecologicalplanners since 1960s;As a pioneer of applying subjectively ecologicalprinciples to urban and regional landscape planning,he created a scienti-fical ecological planning method which has a far-reaching affect to mo-dern planning and design science in the world.This paper introducesMcHarg's philosophic idea and his ecological planning method,clarifiesthe perspective of applying the method to landscape planning and designin China.
摘要:This paper proposes integral equation to find the criticalbuckling load of compression bars in mechanics of materials,thus theresearch method of this problem has been improved.
摘要:In this paper,the geological background as well as thedevelopment characteristics,deformation rupture behavior,and slideformation mechanics of the old and new slide area and the creeping rupturezone of Chongqing Shijialiang Landslide are analyzed in full detail.Onthe basis of this,the forecasting comment on the stability of the slide ismade and the protection measures are suggested.
摘要:This paper atempts to analyse thee heat transfer processin the translucent slab,presents a mathematical model to find the solutionof temperatue distribution,and shows that the translucent slab can workas a heat barrier
摘要:Research results show that chevron-shaped tube has adva-ntages of better hydraulic condition needed for sedimentation and adapta-bility for treatment of raw water turbidity.This paper points out the wayto select the construction parameters of chevron-shaped tube.The contrastresearch between chevron-shaped tube and honeycomb-shaped tube has beendone.The formula of hydraulic characteristic parameter of chevron-shapedtube is given.This formula sets out a theoretic base for practical applicationof chevron-shaped tube.
