Research on Financing Plan for International Cooperative Project in Housing Industrialization

Housing industry is a prop industry with great potential, but it is restricted by shortage of funds. So it is necessary to probe the financing system of housing industrialization in China. This paper puts forward a financing plan for the international cooperative project in industrialized housing in Chongqing. Furthermore, it investigates the concrete financing system of the whole housing industry.     

A Study on the Reduction of Hexavalent Chromium Ion in the Process of Sintering and Ironmaking

The basic principle of using chromium leach residue as melting flux of blast furnace is introduced in this paper.The reduction thermodynamics of Na 2CrO 4 and chromium oxides in the process of sintering and ironmaking is studied,and the simulating experiments in the laboratory and industrial experiments in 600 m 3 blase furnace are carried out.The results of thermodynamical study and experimental study show that hexavalent chromium ion in the burden can be well eliminated in the process of sintering and ironmaking.     

An Expert System Approach to the Computer Aided Design of Intelligent Controllers

The idea for an expert system approach to the computer aided design of intelligent controllers (ESCAD1C) is discussed and the idea of two step modelling of an intelligent controller is presented on the basis of emulating human control behaviours to solve complex problems. The structure, functions and characteristics of ESCADTC system , and the design procedures of intelligent controllers are gived. The knowledge base and simulating functions for designing intelligent controllers are also described.     

A Study on Human Simulation Intelligent Control Algorithm to a Category of Objects

Based on the model of Human Simulation Intelligent Controller (HSIC) presented briefly, a detailed algorithm was described for the servo system control by using the method of HSIC. Simulation results obtained proves the good performance of the control algorithm.     

A New Monte Carlo Method Based on State Analysis

A new Monte Carlo Method for system reliability evaluation is proposed in this paper. The repeated sampling of system states with relatively great probabilities is avoided in the simulation,thus the sampling efficiency is significantly improved. Besides,the negative correlations used in different trials can further reduce the estimated varinaces. The sparse matrix technique is employed to reduce the memory requirement and to save the computer time. Comparative studies show that the method proposed is of great value and the application to the IEEE reliability test system (power system) is successful.     

THE MIXED MODE FRACTURE CRITERION OF BRITTLE ROCK UNDER COMPRESSION-SHEAR STRESS STATE

In this paper the test results of mixed mode fracture of three kinds of brittle rock under two kinds of stress paths are reported. The fracture mechanism and failure patterns of brittle lock under different stress paths are discussed. Theory analysis and test results show that the Compression- Shear fracture criterion of brittle rock can be expressed:     

白血病抑制因子（LIF）及其受体在月经 周期猕猴卵巢内的表达

应用免疫细胞化学方法对白血病抑制因子（leukemia inhibitory factor, LIF）、白血病抑制因子受体（leukemia inhibitory factor receptor, LIFR）和gp130在月经周期猕猴卵巢内的表达进行了研究。结果表明：LIF、LIFR和gp130在猕猴卵巢内的表达量随月经周期的不同而变化，LIF及其受体在增殖期卵巢内的表达量高于分泌期的卵巢。LIF及其受体在原始卵泡、腔前卵泡和有腔卵泡的卵细胞内表达量均较高，在颗粒细胞、卵泡膜、卵巢生殖上皮和卵巢基质中有少量表达，而在闭锁卵泡、退化的黄体和卵巢髓质中未见表达。LIF及其受体在猕猴卵巢内的表达可能受卵巢分泌的类固醇激素所调控，LIF可能通过自分泌或旁分泌的方式在猕猴卵泡发育及排卵等过程中起重要作用。     

ANALYSES FOR DEFECTS OF 18G_2ANb STEEL SPHERICAL TANKS OF NATURAL GAS

Calculations and analyses are made with the CVDA, IIW, JWES standards for the strength and welding defects of two spherical tanks of natural gas in CHONG QING. The results of the analyses indecate that though there are some problems with the welding quality in these tanks, they may still be used with the desingned presure. Now the formal working of these two spherical thanks has verified of the validity the calculations and analyses.     

Detection of Edges within the Cross Sectionfrom Projections of Parallel Beams Via the Wavelet Method

The wavelet analysis are used in the detection of edges within the cross sectionfrom projections of parallel beams. This method can be applied in computerized tomography (CT) inorder to reduce the noise and the number of projections.
