METHODS The extracting conditions of percolation were established and taken the overall yield and the content of oleanolic acid as markers .
方法以醇浸膏得率,齐墩果酸含量为指标,考察渗滤法提取亲脂性部分的工艺条件;
Methods : adopting the acid dye colormetric method to determine the contents of total alkaloids of Sophora flavescens Ait from the three extracting liquids such as water regurgitation , ethanol regurgitation and ethanol percolation .
方法:采用酸性染料比色法,对苦参水回流、醇回流、醇渗滤三种提取液中的生物总碱进行含量测定。
Methods : Five kinds of conventional extracting solution of Hirudo ( alcohol and water extracting , alcohol refluxing , water extracting , water extracting-alcohol precipitating , percolation filtration ) were used in this study .
方法:以五种常用中药提取法(水醇双提法、乙醇回流法、水提法、水提醇沉法、渗滤法)提取水蛭;
The results showed that the volume resistivity of the composites decreased visibly as the nano - MoS2 content is above 15 wt % , the percolation threshold of the composites was 15 wt % .
结果表明,当二硫化钼质量分数大于15%时,体系的电阻明显下降,复合材料的渗滤阀值为15%;
As the result , the conductive fillers'structure has a great influence on LDPE / graphite conductive composites ' conductive property and mechanical property . The composites composed of expanded graphite have the lowest percolation threshold , but the composites'mechanical property is low .
At last , the thesis takes an eco-residential sub-district in Chongqing as example , and explain the design and calculation of water circulating system of mountainous eco-residential sub-district , through the calculation of the reclaimed water and runoff , the dimensional calculation of the soil capillary percolation system , the annual cost none-linear design of the united system of the reclaimed water and rainwater , as well as the use of software Logo .
