It was established that, the fish skin was stirred two times with 2.5% or 5% NaCl solution at a ratio of material to solvent of 1:10 at about 5℃ for 12h, about 5.9%, 6.7%, 9.1% soluble non-collagenous protein could been separated from skin of silver carp, bighead carp and grass carp, then by homogenizing with acid at a ratio of material to solvent of 1:30, about 78.9%, 84.1%, 82.0% of collagen from skin of silver carp, grass carp and bighead carp could be extracted by acetic acid or citric acid.

结果表明，鲢、鱅鱼皮经2.5％NaCl溶液(1：10)，草鱼鱼皮经5％NaCl溶液(1：10)，温度5℃左右，12h磁力搅拌处理二次，除去的可溶性蛋白分别占原总蛋白的5.9％、6.7％、9.1％。鱼皮再经加酸(1：30)溶胀、均质处理后，即可得到鱼皮胶原蛋白的粗提取液，鲢、草鱼鱼皮的酸提取回收率以醋酸为最高，分别为78.9％、84.1％，鱅鱼皮以柠檬酸为最高，约为82.0％。

After dryness, silica powder is put into chlorinated furnace in fluid bed and reacts with dried hydrogen chloride gas in the environment of 340℃ to form crude trichlorosilane. The crude trichlorosilane , through hydroscrubber and pipe bundle condenser to extract silicon tetrachloride in distillation column produces trichlorosilane gas out of the d istillation column , which can be made into the finished product of trichlorosilane by condensation .

硅粉经干燥后加入氯化沸腾炉，与通入炉中的干燥氯化氢气体在340o C进行反应，生成的粗三氯氢硅经湿法除尘器、列管冷凝器去蒸馏塔分离匹氯化硅，由蒸馏塔出来的三氯氢硅气体经冷凝，制得三氯氢硅成品。

Thereby the fundamental principle of the single practice faction of Taoist theory for inner elixir is come out. Then, mainly according to Wuliu Xianzong and Dacheng Jieyao, author elaborates the approximate appearance of the single practice faction of Taoist art for inner elixir such as"Constructing the foundation in one hundred days","Plucking the great medicine in seven days","Hibernating in Seven days","Keeping the embryo in ten month","The positive deity leaving the body","Cultivating in three years","Seating in front of a wall in nine years"and so on. At the same time common misunderstandings that cause to some terminology are clarified such as "The Xing before the Ming"and"The Ming before the Xing".

文章通过对内丹学南宗、北宗和中派的代表性丹经的发掘和整理，明确这些丹经中的&先天&、&后天&、&元神&、&元气&、&元精&、&阴阳&、&造化&、&心&等等主要概念的基本含义，从而归纳出清修派内丹学的基本理论，接着，主要以《伍柳仙宗》和《大成捷要》中所阐述的内丹术为主要依据，综合南北宗和中派的代表性丹经，把清修派内丹术中的所谓&炼心&、&百日筑基&、&七日采大药&、&七日大蛰&、&十月养胎&、&出阳神&、&三年乳哺&和&九年面壁&等基本丹法大要较清晰地呈现出来，同时澄清人们由于对一些术语概念认识不清而导致的误解，如所谓&先性后命&和&先命后性&的区别。

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution.

结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。

At first, the broth was acidified, then centrifuged to get mycelia, which was heated and powdered; finally we use acetic ether to soak the powder. After that, the phase of acetic ether was washed using the solution of ammonium sulfate and the solution of ethanedioic acid, then concentrated to gain pulps. It was crystallized at 4℃.The coarse crystals was decolorized by activated carbons, the pure needle crystal of lovastatin was obtained.
