The edge detection rate of the traditional edge detection operators is relatively high, so that some edge points with special characteristics can’t be separated from the normal state edge points. With the specific machine vision applications, a new prediction method for edge detection based on human visual feature is proposed in this paper, and the normal state edge points can be removed by changing the method’s parameter. After the experimental verification, the laceration edge points of the sausage can be extracted precisely.

Polyaniline was obtained by chemical oxidation in the microemulsion system consisting of aniline, emulsifier, assistant emulsifier and water in magnetic field （0 T, 0.2.T, 0.4 T, 0,6 T）. The effect of magnetic field on the polymerization rate and the inherent viscosity of polyaniline were studied. The molecular structure of polyaniline was characterized by IR spectra and the thermal degradation behavior was assessed using TG techniques. The results show that the polymerization rate, molecular weight, thermal stability and conductivity of the synthesized polyaniline enhanced and no effect on the basic structural units of polyaniline was observed in magnetic field, Within the range of the intensity of magnetic field studied, the magnetic field of 0.4 T exerts the largest influence on polymerization of aniline.

＜正＞The problem of robust output tracking of nonlinear systems is considered in this *** systems under consideration are subjected to actuator *** main difficulty in system design is that not only the fault information but also the function of the system model are *** on the universal approximation property of fuzzy system, a novel control scheme is proposed to guarantee the stability and desired output tracking performance of the closed-loop system,though there are unknown nonlinearities and actuator *** from existing works,the fuzzy systems used to approximate the unknown functions are nonlinearly parameterized,which removes the restriction that the fuzzy basis functions must be well known before control *** effectiveness of the proposed control scheme is verified by a simulation example.

The carbonized structures of Mo La 2. 3 cathode specimens have been investigated by means of FESEM and XRD, respectively. The substructure of carbonized layer in the Mo La 2. 3 cathode has been found for the first time. The results showed that the carbonized layer with uniform Mo 2. was helpful to emission, while the demixing carbonized layer with a compact MoC outside layer was harmful to emission. The uniform Mo 2. layer consists of coarse particles with lots of grain boundary crevices as well as holes arranging perpendicular to the wire axle and up to surface, which was beneficial to the migration of activated rare earth in activation and operating.

Gas-liquid two-phase flow occurs increasingly in some dynamic devices operating in the oceanic condition. The relative data are limited with respect to flow characteristics, so the present study is to investigate systematically single-phase pressure drop, and to develop the theory for frictional factor under the roiling condition. Using deionized water as the test fluid, a series of experiments of single-phase flow were conducted in pipe with the inner diameter of 34.5 ram. The test section was horizontally settled on the rolling apparatus, and its regularity was similar to simple harmonic motion. It is found that the pressure drop during rolling motion fluctuate with the change of the rolling period and rolling angle, which is significantly different from fluid motion in a steady state. By the contrast between experiment results and stable-state theory values, existing correlations can not predict present frictional factor very well. Therefore, in the present article, the single-phase frictional factor is correlated with the Reynolds number for rolling motion, and its computated results agree well with experimental data.
