The total flavonoids content of peanut hulls of different sources were evidently different,those peanut hulls contained more total flavonoids from Shandong province,higher maturity and raw. This suggested that attention should be paid to the choice of peanut hulls as medicine materials. 3.The optimized extraction technology conditions considering the two indices of total flavonoids andβ-sitosterol were: the peanut hulls were extracted by 95% acohole 6 times of the hulls weight refluxing for 2 hours first,and extracted by 70% acohole 4 times of the hulls weight refluxing for 2 hours at the temperature below 80℃successionally,then the concentrate was dried vacuumizedly with the additament of starch 2% of the concentrate weight after the extracts were fitrated,united and concentrated. 4.The dried extract powder possessed high hygroscopy and low fluidity,but the weight variation of capsule contents could comply with the requirement of CP if it was mixed with dextrin and granulated by sieving 40 meshes using 95% ethanol as the wetting agent,and filled into capsules after dried below 60℃.The critical relative humidity of the granules was about 63%.

不同来源的花生壳总黄酮含量有较大差异，山东产区、成熟度高的及未经炒制的花生壳总黄酮含量较高，提示作为药材时应注意选择； 3、兼顾总黄酮及β-谷甾醇的最佳提取工艺为：先以95%乙醇6倍量加热回流提取2小时，再以70%乙醇4倍量80℃以下回流提取2小时，提取液过滤、合并、浓缩，加2%淀粉60℃以下减压干燥； 4、浸膏粉吸湿性大，流动性差，但加糊精并以95%乙醇为润湿剂、过40目筛制粒，60℃以下烘干后填充胶囊，可保证装量差异符合要求；颗粒临界相对湿度约为63%。

In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.

本文对水煤浆气化炉喷嘴进行了简化处理，在此基础上，对气化室内的冷态流动过程进行了研究，发现：整个气化室都处于流动的回流区长度范围以内；水煤浆气化炉中，由于操作压力很高，气相密度很大，所以即使对于d〓=150μm的较大煤颗粒，其对流体的跟随特性也很好，没有发生流动特性突跃的现象；两相的最大回流速度、回流强度，颗粒相的浓度分布，以及气化室内的静压力损失等，均与气化炉的负荷、水煤浆浓度、煤粒直径、O〓在喷嘴两个流道中的分配比例。

The nozzle of the gasifier is simplified. The cold-flow field in the gasifier chamber is studied. The research shows that the chamber has recirculation along the whole length. The particles in the chamber perform a very good flowing characteristics even for the large particles of dp=150μm, and no abrupt change is observed. This is due to the operational pressure is high and the density of the gas is large there. The maximal reflux velocity of both phases, the reflux intensity, the concentrational distribution of particles, and the static pressure loss in the chamber are all related to following factors: the load of gasifier, the concentration of coal-water slurry, the diameter of the coal particle, the distribution ratio of oxygen in the two channels of the nozzle, and the angle of jet in nozzle.
