Linear solvation energy relation was firstly introduced in the paper, and the method and step of gaining the special parameters of solvent and solute were introduced in detail, and these special parameters were used to selection and optimization of extractive agent in extractive distillation. The model of predicting activity coefficient at infinite dilution was established by linear solvation energy relation. By the above theory, several candidate solvents were selected to separate C5 fraction, and by experiment of vapor-liquid phase equilibrium at atmosphere pressure, the mixture of N-methyl-pyrrolidone including 4% water was used extractive agent of separating C5 fraction. Then binary vapor-liquid phase equilibrium of the some compound in C5 fraction and N-methyl-pyrolidone were determined at atmosphere pressure and correlated by NRTL equation. Isoprene being objective compound, experiments were operated in the laboratory-scale column; the processes were simulated by RadFrac model in ASPEN PLUS. And by the combination of experiment and simulation, the new process of separation of C5 was established.

Design is human"s pondering outcome, it is a kind of conceivableness, proposition too.by actualizing,reaching the terminated aim of satisfying human"s demand .design is influenced by cluture and expresses clu-ture.design conveys ideology ,and architecture carries design.cluture is the distillation of a civilizaiton,and architecture is a kind of the material form of cluture .so design cant be disvorced from societal culture background ,the two parts is so consanguineous.the article is try to use this measure,hunting the cluture background of the aulic archi- Tecture of qing dynasty, seek the path of distinguishing display of qing dynasy and ming dynasy.point out the relationship of design and archi-tecture of different time.

设计在文化的影响下体现出文化的特征；设计通过建筑的形式传达思想，建筑成为了设计的载体；文化是一个文明社会的精髓，而建筑正是文化的一种物化的形式。因此，设计是不能脱离社会文化大背景而独立存在，它们两者之间是密不可分的关系。而本课题正是通过研究清朝宫廷的建筑来探求设计背后的文化背景，为寻求明清陈设的差别找到出路，并指出不同时期设计与文化的关系。以便给以后的研究廓清思路，理顺线索。
