In order to optimize the motion characteristics of slide-valve in water hydraulic servo-valve. Hydrostatic bearing technology has been used between valve core and sleeve. The research on performance about the static characteristics of slide-valve in water hydraulic servo-valve with hydrostatic bearing structure and traditional throttle with fixed orifice has been carried. The mathematical model of the pressure-flow characteristics, the pressure sensitivity characteristics and pressure characteristics of servo-valve has been established. Research shows, the application of hydrostatic bearing technology can make the linear relationship of the pressure - flow characteristics of the nozzle-flapper valve maintained, the pressure sensitivity can be maintained constant, but pressure characteristics of servo-valve become worse.

The stress fields in a steel bridge girder under cyclic loads were calculated by elastic-plastic finite element method. It is shown that the load application on the pre-stressed component produces a reassessment of the stress field and, in particular,a relaxation of the maximum stress; the relaxation process is almost limited to the first cycle; the degree of the residual stress relaxation is mainly controlled by the cyclic loading with the largest amplitude under variable amplitude loading. Based on the laws above, the shakedown behavior of steel girder under moving train load was analyzed and the redistributed residual stress field was acquired.

The cationic polymer/bentonite nanocomposite adsorption materials were prepared by cationic polymer-epicholorohydrin-dimethylamine (EPI-DMA) and dimethyldlammonium (PDMDAAC) as intercalary reagents, respectively; then the adsorption performance for p-chlorophenol (p-CP) were discussed. The results indicated that the adsorption ability of cationic polymer/bentonites for p-CP increased with the increase of polymer contents and the length of polymer chains. The adsorption kinetics were well described by first-order kinetic model, Bangham kinetic model and intra-particle diffusion model; the adsorption isotherms were also modeled according to Langmuir and Freundlich adsorption isotherms. Increasing solution pH was propitious to adsorption process and the adsorption process was exothermic reaction and was presented by heat evolution physical sorption and organic partition.

Quantitative evaluation for estimating motor function is a prerequisite for clinical application of rehabilitation robot. The current clinical evaluations, such as Fugl-Meyer assessment, still have some deficiency. The study provided an innovative evaluation method, which contrasted the physiological character of impaired limb with the contralateral upper limb of post stroke hemiplegic patients, and investigate the comparability of surface Electromyography (sEMG) between patients and healthy persons during robot-assisted motor recovery training possess similar track and equivalent velocity. There is much comparability of sEMG characteristic in healthy limb of patients compare with healthy person, yet less comparability exist in the impaired limb. The results in the study imply that the method depend on contralateral limb sEMG characteristic have potential capacity in clinical quantitative evaluation of rehabilitation and may competent to associate with other physiological character.

The closure of Multi-span continuous rigid frame bridge is one of important steps in its construction. The selection of closure scheme determines the deformation and stress state of the bridge when construction is completed. In this paper, based on the situation of Jing River Bridge, which is now under construction in Gansu Province, finite element method is applied to analyze and compare the inner forces, stress and deformation of the bridge with five possible closure schemes. As a result, the most reasonable and engineering feasible closure scheme is obtained.

The rapid development of economic is inseparable from the support of resources, while the huge consumption quantities of resources will inevitably lead the negative impact to the environment of mine, such as the poor environment for production of the mine, discharging the “three kinds of wastes”, geological disasters, and the destruction of environmental resources, etc. How minimize the extent of environment pollution and damage, and how protect and manage the environment of mine, which have become a focus of the whole society. In modern mining, non-waste mining is an important issue, because it can solve these mentioned environmental problems of mine, and changing the traditional downward-type mining technology to upward-type exploitation, will leave the waste rock in the tunnel of mine and reduce the collapse area, at the same time, which will be very effective on discharging wastewater. So it is very promising way to reduce the environmental problems of mine.
