The prediction of hydrodynamic characteristics and motion responses is investigated numerically with CFD software FLUENT and self-developed program. Variations of resistance, lift and moment under the condition of the air effect is considered or not at different Froude numbers are numerically simulated. Predicted results show that the lift and moment change obviously when the air effect is included. The maximum increase of lift reaches 31.78% while the reduction of moment is 31.84% at Fr=5.0.Heave-pitch motion characteristics of planing boat at Fr=1.5 is numerically simulated by the real-time solution of planing boat motion equations, time history curves on height of center of gravity and pitch angle are presented.

Loads of two linear guides have been analyzed by mechanics theory. A simplified mechanical model of Permanent Magnet Linear Synchronous Motor (PMLSM) feeding system is established with a VH1100 high-speed vertical machining centers as the object of study. On the basis of the simplified mechanical model, when moving parts are in different stroke of X-axis, deformation of a gantry type beam has been analyzed by finite element method. Deformation of the beam has been measured. The normal force of PMLSM has been achieved by finite element simulation and relevant experiments. The simulation results are in good agreement with measured data, indicating the accuracy of the model.

In this study, the composite of pre-reservoirs system was designed and to explored the removal of suspended particles (SS) in the non-point sources pollution. The operating parameter (residence time) was investigated its effect on the SS removal, and the particle size distribution of effluent was analysis. The results showed that this system could remove the SS with high efficiency. When the residence time was 24hrs, SS could remove over 90%. From the Particle Size Distribution analysis, the results revealed that the particle size > 30µm and <4µm of SS cloud be removed in sediment area by physical sedimentation. And the particle size of 3∼9µm of SS cloud be removed in deep water area by plants interception.

With the extensive application of pre-twisted beam in engineer structure, it is very important to carry out systematic analytical research of pre-twisted beam, put forward a dependable mechanics analysis model and the calculation theories. The paper carries on mechanical property based on small deformation assumption to get the displacement general solution, and verify its accuracy using ANSYS software. The paper indicates that the general displacement method is feasible, and the displacement of pre-twisted cantilever beam is larger than non-twisted beam, and the lateral displacements appearing, because of pre-twisted angle. At the same time, the presented general solution offers an accurate displacement interpolation model.

An automatic, convenient method combined flow injection technique for determining organic phosphorus pesticide in environment water was developed based on the inhibition effects of organic phosphorus pesticide to plant-esterase. The optimized determining conditions were acquired, and the analytical characteristics of this method were studied. The linear ranges of dichlorvos' standard curves was 0.008 ∼ 4mg/L. The linear equation of dichlorvos was U(mV) = −4874.4 C (mg/L) + 110313. The correlation coefficient of dichlorvos was 0.9984. The detection limit (S/N= 3) was 0.02mg/L for dichlorvos. The relative standard deviation (RSD) of dichlorvos was 1.04% (n=6). The recoveries ranged from 95% to 105%. The analysis result was good.
