ZCMJ high efficiency roughly grinding machine produced by our company is mainly suitable for not only before-boiling rough grinding of straw, bagasse, bulrush, wooden flake, cotton stalk, paring, sawdust, shrub and hemp stalk, but also rough grinding of raw material fermented by natural living substances or soaked in limewater and after-boiling rough grinding.

我厂研制创新生产ZCMJ高效粗磨机，该机主要用于造纸制浆。既适用于麦稻草、甘蔗渣、芦苇、木片、棉杆、刨花、锯屑、节子浆、灌木、麻杆等蒸煮前的粗磨，也适用于通过自然生物发酵，或石灰水浸泡后的原料的粗磨，更适用于蒸煮后的粗磨。

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。

The existing stone cutting tool, the tool bit is constituted by the sole grade's grinding material, when cutting the rough stone, the cutting speed is quick, the cutting efficiency is high, but the cutting surface fluctuates in a big way, becomes rough, after the cutting, grind and polishing take long time to do, if use the fine grinding compound, the cutting face is smooth, but the cutting speed is slow, the cutting efficiency is low, therefore the existing stone material cutting tool cannot have the high efficiency to cut the stone which have the smooth cutting surface, in view of this, how to keep the high working efficiency and get smooth cutting surface?

现有石材切具刀头由单一粒级的磨料构成，使用粗料时，切割速度快，切割效率高，但切割面起伏大，变得粗糙，切割后研磨抛光耗费时间长，使用细磨料，切割面较平整，但切割速度慢，切割效率低，因此现有石材切具不能高效率地切割出平整的石材，针对这一现状，如何既能高效率切割，又能使切割面保持平整呢？
