By summing up the practice, the author discusses a system of solutions on the designing and calculating program of heating residential buildings in Henan cold district.
Firstly, the status quo, content and sense about the optimal design of water supply networks are introduced. Hydraulic theory of water supply networks and the theory and flow of optimization methods-GA are discussed.
In order to make full use of the worm-gearing performance, it is the design calculation process of parameter calculation,macro-quality observation,micro-quality parameter calculation, carrying power proof-test be ascertained.
Combining“Concrete Structure Design Code”(GB50010-2002)and “Technical Specification for Strengthening Concrete with CFRP”(CECS146:2003),this paper introduces a basic calculation method of shear strengthening for reinforced concrete beams and columns,and gives design calculation flow chart of flexural strengthening and realizes software design by Visual Basic.
This paper deals with the deduction,resolution and transform-ation of diamlike matrix D for ordered quantity optimum segm-entation.Computation flowchart has been reasonably formulatedapplying iteration dense caculation and using fully transmition ofintermediate data.With the present method,the caculation mountwill be reduced,the internal storage capacity of computors savedgreatly,and the operation period shortened by four times.Its soft-ware has been made for pocket computers as PC-1500 or PB-700,and can al...
本文论述对“有序量最优分割法”中,类直径矩阵 D 的计算公式推导、分解与交换过程。采用“递推”紧凑算法。充分利用中间性数据的传通,巧妙设计计算流程,比原算法大大减少计算量、节省计算机内存容量,缩短计算机运行时间4倍以上,实现 PC—1500、PB—700 等袖珍型计算机应用程序软件。同样可移植到一切能使用BASIC 语言的微、小型计算机上实现。
The design of high energy gas fracturing(HEGF)is crucial to the further development of the technique. This article presents a preliminary approach to the design method of HEGF. The content of the design comprises applicable circumstances, design of pressure history, analysis of propellant burning, analysis of gas drainage from wellbore, analysis of fracture propagation, prediction of stimulating effect, etc. As the working medium is compressible gas out of burning propelllant, the above analyses are interre...
The paper has given a detailed computational method of design of light transmissivity of Sunlight Greenhouse, and proposed a standard of design. It says, the accumulation of average for intensity of illumination during 6h (The average is more than the lightcompensation point:4000 1x) must be more than 20, 000 1x. According to this standard, thepaper has provided a computational process with respect to light transmissivity of sunlightgreenhouse.
