The effects of solution\'s pH value, mol ratio between phenyl aldehyde and L-Arginine, concentrations of sodium chloride, ammonia chloride andL-Lystine, initial concentration of L-Arginine on precipitation rate of a -tolylene arginine were investigated, the results indicated that phenyl aldehyde precipitation method\'s appropriate pH value was higher than 11, suitable mol ratio between phenyl aldehyde and L-Arginine was 1.25, initial concentration of L-Arginine was must higher than 15g/L, sodium chloride had little effect on precipitation rate, on the contrary, ammonia chloride and L-Lystine had great effect on it, both of them must be eliminated; At the same time, adsorption isotherm at 25 C of L-Lystine on anion exchange resin A was measured, the result showed that the maximal equilibrium adsorbance was 30mg/g, the influences of solution\'s pH value, temperature, concentration of chloride ion on adsorption of L-Lystine by anion exchange resin A were also studied, the results indicated that appropriate operational pH value was 0.5 0.2, the effect of temperature on adsorption ratio was little, process could be operated at room temperature, the concentration of chloride ion must be eliminated.

考察了溶液pH值、苯甲醛与L-精氨酸摩尔比、氯化钠与氯化铵浓度、L-赖氨酸浓度、L-精氨酸初始浓度对苯甲醛沉淀L-精氨酸的影响，结果表明，沉淀反应的适宜pH值大于11，苯甲醛与L-精氨酸的适宜摩尔比为1.25，(来源：Aa6BC论文网www.abclunwen.com)L-精氨酸适宜的初始浓度在15g/L以上，氯化钠的存在对沉淀率基本上没有影响，而氯化铵和L-赖氨酸的存在使沉淀率下降；同时测定了25℃时阴离子交换树脂A吸附L-赖氨酸的吸附等温线，表明其最大平衡吸附量为30mg/g，考察了溶液pH值、温度、氯离子浓度对阴离子交换树脂A吸附脱除L-赖氨酸的影响，结果显示从L-精氨酸和L-赖氨酸混合液中吸附分离出L-赖氨酸的适宜pH值为10.5±0.2，温度对L-赖氨酸吸附率影响不大，吸附过程可在室温下进行，氯离子的存在使L-赖氨酸的吸附率降低。

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.
