Ethyl cellulose membrane material has produced in physical modification method. The fundamental characteristics of reverse osmosis on EC membrane can be correlated with HPLC experimental conditions. By using EC membrane material as column packing, double-distilled water as mobile phase, the retention times are measured with suitable inorganic and organic compound as solutes.3. Complying with the retention times, the partition coefficient of the solute and the ratio of the surface excess concentration of solutewith the concentration of the parent fraction are calculated .

稳态流程与时间无关，是化工流程模拟中应用最为普遍的重要技术之一，需要建立质量平衡、相平衡、摩尔分数归一化和能量平衡等(MESH—Massbalances，Equilibrium relations，mole fractionSummations and Heat balances)方程构成的数学模型来描述其工艺流程中状态参数的分布情况[6，8-9]。

The aim of all yogic and other spiritual practics is to release the great cosmic power or kundalini shakti which lies coiled three and a half times in mooladhara chakra .the process of awakening this force,or prana ,is described in the scriptures as ,"the flight of a bird sising from earth to heaven ,tied to a golden thread ".the earth is mooladhara chakra ,heaven is ajna chakra ,the bird is mahaprana and the golden thread is sushumna nadi which runs through the centre of the spinal column,by manipulating ,storing and expanding the prana within the body it is possible to awaken the sleeping prana shakti .this is the fundamental purpose of the yogic sciences of pranayoma (expanding the dimensions of prana )and prana vidya knowledge of prana

所有瑜伽修行者和其它精神上的习练者的目标是唤醒被牢牢束缚纯真轮的在力量。这个过程就是启动巨大的宇宙力量或者是灵性的能量，这个过程被描绘成这样的一幅图画：金色的鸟从地球飞向天空，但由于重力却飞不上天空，被一根金线牢牢的束缚。那么这里，地球就是纯真轮，天空就是眉心轮，飞鸟就是巨大的能量，那金色的线就是中脉，是贯穿脊柱的通道。通过操纵、储藏和扩充身体内的能量从而有可能唤醒休眠的能量。这是瑜伽呼吸科学和瑜伽能量知识的基础。
