The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.

结果显示：细胞3个生长时期的持续时间与接种量、初始营养浓度、营养流加情况及培养条件有关；分批培养和流加培养时的最大细胞得率分别为12g/L和35g/L；细胞的皂甙含量在旺盛生长期快速上升，并保持增长至衰退期前期；干细胞中最大的皂甙含量达60~70g/kg；随着细胞的生长，培养液的电导值从8000μS以上下降至600μS以下，细胞自溶后逐渐回升。另外，培养后期部分细胞颜色变红，但没有发现颜色转变对皂甙含量造成影响。

The bud gave the best rege.neration with4 regenerated shoots fxom each explant of Basella in average when subcultured in a combination of 2 mg/l 6-BA + 0.3 mg/l NAA.

The results show that the change in the oscillating period was linearly proportional to the concentration of Benzylpenicillin Sodium over the range from 2.47mg/L- 0.0123mg/L. Using the procedure, the content of the antibiotic in a bought production is determined and the result was consistent with that by HLPC.

实验结果表明，当体系中青霉素浓度在2.47mg/L-0.0123mg/L之间时，青霉素的浓度与进样后周期的变化率存在良好的线性关系，以此作为定量分析的基础，去测定市售注射用青霉素G钠的有效含量，与高效液相色谱测定结果一致。

The toxicity of trichlorphon would become degradation after a week under the same conditions. For example, the survival rate of Daphnia pulex reached to 100 percent in the concentration of 200μg/L after 144h and 65 percent in the concentration of 400μg/L after 168h.

在相同的实验条件下，敌百虫溶液的毒性可在一周后降解：如200μg/L的敌百虫溶液在放置144h后，蚤状溞的存活率就达到100％；168h后，400μg/L的存活率为65％。
