The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis. Then the best technology conditions were ascertained for different extraction aims.2 The pretreatment of rough material should be needed before extraction. Comminuting the material to 0.28mm size is most fit to SC-CO: extraction.3 Firstly static extracting 20 min then turn to dynamic doing is the better extraction mode than other ones.4 The orthogonal experiment was conduct with 3 factors and 5 levers.

本论文通过对非洲山毛豆SC-CO_2萃取中影响萃取效果的工艺条件的研究，初步得出如下结果：(1)本论文中所采用的萃取效果评价方法适宜于非洲山毛豆中鱼藤酮的超临界流体萃取技术研究，该方法具体为：HPLC定量分析非洲山毛豆SC-CO_2萃取物中的鱼藤酮含量，再结合萃取前后处理样品的重量损失，得出鱼藤酮萃取率、萃取所得粗物质萃取率和粗物质中鱼藤酮含量三个参数，以此三个指标综合评价萃取条件对萃取效果的影响；(2)通过对原料粒度对萃取效果影响的研究，结果表明SC-CO_2萃取非洲山毛豆复叶中的鱼藤酮，原料粉碎成30目粒度叶粉时萃取效果较好；(3)通过对萃取方式与萃取效果之间关系的研究，结果表明SC-CO_2萃取非洲山毛豆中鱼藤酮应采用先静态后动态的萃取方式，静态萃取时间为20min；(4)通过温度、压力和CO_2流量三因素五水平的正交试验，结果表明温度是最主要的影响因素，压力因素对鱼藤酮萃取率的影响程度高于CO_2流量，而对于粗物质萃取率和粗物质中鱼藤酮含量CO_2流量因素高于压力。

Three results are obtained by an orthogonal experiment. The main components of essential oil in separating containerⅠare terpenoid, terpeneless compound is in separating container Ⅱ. Through second-level separation the technological conditions of de-terpene are: pressure 7MPa, temperature 32℃ in separating containerⅠ;pressure 4～5MPa, temperature 32℃ in separating containerⅡ. The optimum technological parameters of obtaining two essential oils are: particle size 0.60mm, pressure 10MPa, temperature 36℃, operating time 90 minutes. There are 1.46% and 1.88% essential oil in separating containerⅠand Ⅱ respectively.

通过正交试验表明：分离器Ⅰ中精油的主要成分是萜烯烃类化合物，分离器Ⅱ中精油的主要成分是由高级醇类、醛类、酮类、酯类等组成的含氧化合物；二级分离脱萜的适宜参数是：分离器Ⅰ的压力为7MPa，分离器Ⅱ的压力与循环压力相同，温度都为32℃；同时得到萜烯烃类精油和低萜精油的最优工艺组合是粒度0.60mm，萃取压力10MPa，萃取温度36℃，萃取时间90min，精油得率分别为1.46％和1.88％。

The results showed that the interaction between temperature and pH value had a significant effect on the growth of thiobacillus ferrooxidans.

研究结果表明其最优适宜环境为：pH=2、温度28℃、初始Fe(上标 2+)+浓度0.15mol/L、初始Fe(上标 3+)浓度为0.06mol/L。

Whether the inner cylinder is drilled or not do not affect obviously the measurement accuracy. The accuracy of the drilled outside cylinder is higher than the undrilled ones, and the drilled holes are better to be equally distributed, further more, the number is less than 36 with the diameter of 3mm. The sealed outside cylinder can lower the measurement accuracy. The thinner material of sealed inside cylinder is and the more ventilative function is, the higher accuracy will be achieved. Moreover, when the space between inside and outside cylinder is smaller, the measurement accuracy also becomes higher.

结果表明：各处理精度均较高，最高达97.40%；内筒打孔与否对测量精度无显著影响；套筒打孔的处理比不打孔的处理精度更高，且孔洞适宜均匀分布，但数目不可过多，直径为3mm时不宜超过36个；套筒封底会降低测量精度，内筒封底材料越薄、透气性能越好精度越高；内筒与套筒的间隔较小时精度更高。

Indeed, one of the strongest arguments for "deregulating" major sectors of the economy is the claim that agencies often cannot learn enough about the regulated industry to make sound policy.

事实上，赞成&取消管理&经济的主要部门的最有力的论点之一是，机关常常不能充分地了解被调控管理的工业以制定出适宜的政策。

Less rainfall in spring is not advantage to egg's breaking ground and hulling and to nymph's feed getting. The egg grows rapidly and has high imago ratio under condition of apprpriate temperature and 3~10mm rainfall per ten days.

春季降雨过少，既不利于蝗虫的破土出壳，又不利于出土蝗辅取食，而在适宜温度范围内每旬有3~10mm的降水，则蝗卵发育最快，出土成虫率最高。
