查询词典 factor

As the primary factor, alkabinity should condition were acquired. As the primary factor, alkabinity should be below 12g/L; the desulfurization effect is optimum when the ratio of tannic and sodiumm metavanadate was 1.5-2; the high absorption temperature is unfavour for desulfurzation 30~40癈 was proved to be effective through experiments.

并得出碱度是影响其脱硫效率的主要因素，总碱度控制在129几以下比较适宜；拷胶和钒在脱硫过程中只是起催化作用，且得到二者比例满足1.5一2时，脱硫效果最佳；温度对脱硫效率的影响主要是在较高温度下会促进副产物 NaZSZO3的生成，所以脱硫反应器中的温度不能太高，经实验证明一般控制在30一40℃。

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.
