In the key step of this method (the process of contour tracking), the paper puts forward the concept of grid right-correlation flag to determine the initial segment of tracking curve. In the tracking procedure, the trend of subsequent points are determined by the combinatorial values of neighborhood cells, and a method is designed to avoid contours crossing. In order to obtain high-quality contour line, it adopts it adopts the linear interpolative method to show a contour chart of accurate localization and better visual effect.

The decisive influencing factor of viscosity in carboxyl-methylation was cross-linking reaction. Carboxyl-methylation was the main influencing factor of solubility and swelling capacity in modification of high content amylose starch. The structure and gelatinization property of different amylose content were analyzed with an Olympus Vanox BHS-2 multi-function optic microscope, and the results were as follows. The structure of ordinary cornstarch was different from the high amylose; gelatinization temperature and pH value of starch were affected deeply by amylose content, but had little difference between the gelatinization of high content amylose starch contained 50% and 70% amylose; pH value had much more effect than temperature on the gelatinization of high content amylose cross-linked starch. Monochloroacetic acid consumption, alcohol concentration and pH value influenced the starch carboxyl-methylation. When alcohol concentration was 60%, pH value 10, monochloroacetic acid/starch mass ratio 55%, the carboxyl-methylation of high amylose cross-linked cornstarch had the best result. With the In-Vitro digestibility model and biodegradation experiment, the digestibility and biodegradability of high amylose cornstarch and its modified starch were detected.

In borate or phosphate buffered NaCl solutions with a constant total concentration of borate or phosphate, E_ increases with an increase in pH. With the increase of the concentration of chloride ions, E_ decreases markedly in the test solutions. Moreover, the buffer capacity and concentration of nonaggressive anions in the test solutions also exerts some effects on the crevice corrosion of Type 304 stainless steel. Furthermore, the cooperative inhibition effect of the environmental factors on crevice corrosion was investigated. The potential of crevice corrosion E_(cc shows a strong dependence on a parameter J, which was called as general environmental factor and defined as the product of concentration of nonaggressive anions, pH, buffer capacity and concentration of chloride ions.
