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。

During the study period, we found that plants were present only in natural creek banks, but not altered ones. Comparisons between natural banks without plants and altered banks revealed no significant difference in both shrimp abundance and distribution. However, there was significant difference in shrimp abundance when natural banks with plants and altered banks were compared, suggesting that construction might have negative effects on plants and, in turm, on shrimp abudance. Comparisons between reproductive and non-reproductive season yielded significant results in both shrimp abundance and distribution, which resulted from the recruitment of juveniles to local populations.

在实验期间，自然河段有水蕴草而整治河段没有水蕴草的存在，比较无水蕴草的自然河段与整治河段，发现无论是数量或出现率都没有显著差异，然而，在有水蕴草存在的自然河段之多齿新米虾数量与出现率则较整治河段高，显示哈盆溪可能因为整治工程影响了底质的型态，导致水蕴草不易生长，进而影响多齿新米虾的数量及出现率；在季节方面，结果显示，不同季节在数量和出现率上都有显著差异，而此差异是因为幼虾在生殖季大量加入族群所致。

Methods The degree of knowing about the prevention and control of AIDS, the rate of high risk behavior, the number of condom use, and the change of the incidence rate of veneral disease were investigated and analysed before and after the programme. The effect on prevention anti control was apprasied. Results 16 months after the programme, pepole were more active to take part in the movement to prevent AIDS, showed more understanding and supporting to those who were engaged in preventing and curing AIDS, and more willing to accept patients with AIDS. The degree of knowledge about AIDS had risen up obviously, while the rate of the high risk behavior had fallen down.
