The concentration curves of iron and nickel interface in the deep drawing steel strip are measured by electron-probe and simulated by error solution of diffusion equation. The mutual diffusion coefficient is acquired on the assumption that the diffusion coefficient does not relate to concentration. Dissimilar to Boltzman-Matona method for acquiring diffusion coefficient relating to concentration, the least square method is used to obtain concentration curve equation for calculating the mutual diffusion coefficient of iron and nickel interface.

Double-layer polymer light-emitting devices (PLEDs),based on poly(9,9-dioctylfluoren-4,7-di-2-thienyl-2,1,3-benzothiadiazole)(PDOF-DBT,m(DOF):m(DBF)=85:15),using alkaline metals, alkaline earth metals and insulated materials as the cathode,show different characteristics. Device with Ba(a thickness of about 3nm) as cathode shows better performance:the external quantum efficiency is 1.6%, and the highest light intensity is close to 4000cd/m~2.The result demonstrates the interface between PDOF-DBT and this kind cathode with good energetic contact, and electron-injecting equilibrium.

The Flow Stress of the compression deformation for 7055 aluminum alloy in the range of 250～450 ℃ is studied by isothermal compression of Gleeble-1500.The results show that the flow stress is controlled by strain tate and deformation temperature:the flow stress increases with increase of strain rate and decreases with increase of temperature,and the flow stress of 7055 aluminum alloy during high temperature deformation can be described by Zener-hollomon parameter.

With an example of local power network,it educes the LSC value and presents the three factors influencing the LSC: network structure, distributing proportion of load, power supply configuration.Based on the theory of LSC,during the reliability calculation, the weak segment of power system is found, and the basis for the design project is provided, so as to satisfy optimal operation and planning.

For a real project in a variable condition, the risk analysis by Monte Carlo simulation is down in this paper. The simulation model involves correlative random variables and different kind of probability distribution. A computer program is developed for risk analysis. Several comparative schemes of the project are analyzed for their risk and foundation of decision-making is provided after that.

In this paper two forms of steel pulling cable systems are discussed:the single suspend cable system and the cable truss. Few discussions have been posed of the single suspend cable system at present, and some views about this system are put forward in this article. Static analysis about the steel pulling cable system is processed and assumptions are presented. This article analyseds several factors influencing resisting wind property, such as the form of structure, the cross section of the cable,and the prestress. The function of the prestress influencing resisting wind property in different steel cable systems is firstly raised. At the same time the method of separating prestress from the tress as a result of strain isspoken. The experiment of real elements of the stainless steel cable truss shows that the tested figures are just confined with the calculated ones.
