Different surface modifiers (stearine acid and titanate coupling agent) were used to modify wood fibers. Effects of surface modified wood fibres on mechanical properties ( tensile strength and impact strength) of fibre-reinforced biodegradable composites were studied,and the tensile fracture surfaces and the interfacial adhesion of composites were examined by scanning electron microscopy,interfacial bonding mechanisms of the composites were explored,the law of change reasones of mechanical properties were analyzed. Results showed that the tensile strength and impact strength of composites improved greatly by adding stearine acid and titanate coupling agent,treatment effect of titanate coupling agent was better than that of stearine acid.

Bio-hydrogen production of starch wastewater by anaerobic fermentation technology was studied in this paper. The results show that the best conditions of continuous hydrogen production are: the HRT is 8 hours and the temperature of the reactor is 35°C, in which conditions, the hydrogen production rate is up to 195.6 ml/g-starch. At the same time, the starch wastewater is degraded with COD removal of 49.5%∼65.8%.

A non-smooth spiral bevel gear rattling model with backlash was established by considering input shaft angle excitation and normal transmission error. Based on the Poisson's impact law, the oblique-impact process was analyzed in which friction was considered between gear teeth, and the relation between the pre-impact state and the post-impact one was obtained. Selecting the tooth face as the Poincaré section, the Poincaré map was constructed, and a calculation method of Lyapunov exponents presented by using the local map method to avoid calculating the Jacobian at the impact points. An example was given to validate the above calculation method. The results show that with increase in forcing amplitude, the motion state of the gear rattling system change from single-sided tooth impact to double-sided tooth impact. The spectrums of the largest Lyapunov exponents are calculated in a large range of parameters.

Industry products in production line need to be printed characters on them. In order to prevent the mistakes of printed characters, the computer vision system is commonly used to recognize the characters on products. Conventional segmentation method cannot correctly separate the characters under the condition of touching characters. In this paper a new method is proposed, which rotates the character image to the horizontal position, and uses the opening operation of morphology to cut the touching characters. Good segmentation and recognition results of characters have been got in experiments.

The machining precision and surface quality of high-speed wire electrical discharge machining (WEDM-HS) have been unable to meet the requirements of growing mold industry and precision parts machining. Since the successful development of WEDM technology in the late 1950s, there is quite a long time to implement one-time cutting and forming based on fine-gauge Electricity parameters, but it is very difficult to obtain high cutting speed and perfect surface quality at the same time in onetime cutting. The multi-cutting is the effective method to solve the contradiction between the cutting speed and surface quality, and obtain the higher processing effects. In this paper, the conditions, process parameter settings and processing effects of multi-cutting HS-WEDM are introduced from how to stabilize the Variations of form and position of the wire electrode, the wire-cutting ways of wire electrode, as well as the high-frequency pulse power supply and tracking control, it provides sufficient basis for further improving the multi-cutting WEDM-HS technology.
