Metal surface treatment by silane provides an alternative replacer to the existing toxic hexavalent chromium passivation technique. This article deals with the two fundamental aspects, viz reactivity and processability, of different hydrolyzing silane systems. By conductivity determination, the conversion of Si-OC2H5 into Si-OH and Si-OH condensation were studied for different hydrolyzing systems. The optimum hydrolyzed system was proposed based the desired balance of reactivity and processability.

The knife-gap accuracy of rolling-cut bilateral shear is one of the key factors influencing the cutting quality. This paper through the site of a high strength low alloy steel shear test, a linear regression equation for the relation between knife-gap and plate thickness is obtained and optimize by using MATLAB Toolbox, after optimization of the linear regression equation can be conveniently used, reduce knife-gap adjustment time, improve production efficiency, reduce shearing defects.

According to Faraday's law of electromagnetic induction,the electromagnetic vibration energy harvester can convert the mechanical vibration of human running or walking to electrical energy, the harvester output is through detection/rectification, two-stage of energy storage, stabilize voltage which is able to reach stable voltage of 4.2V,current of 355mA.The whole system doesn’t need external power supply, the electromagnetic vibration energy harvester has produced two part of the electric energy, a part used to storage, and another part provided power supply for circuit chips. Characteristic of the selected chip is low power and high stability. Analyzing the energy harvester’s structure and principles, a basic electronic circuit for storing the electrical energy is also introducing. The amount of output electrical energy about energy harvester is controlled by magnetic field strength, amplitude and frequency of human movement.

In this paper, the use of overhead ground wires as tension line of bearing cable .Using ANSYS and ADAMAS software ,To establish the dynamic model of power transmission line tension stringing,Considering the force of tension stringing process overhead bearing cable of ground wire. The study of tension stringing of transmission line show that the overhead ground wire as bearing cable of ground wire can meet the requirements of the tension line.

Simple description the background of hydraulic hybrid technology, scope of application. Put forward the idea of hybrid hydraulic system design based on the car's braking performance, the main elements parameter calculation. Simulation results show that the braking process is smooth, brake energy recovery, the system design and parameter calculation of reasonable.
