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.

本文首先对线性溶剂化能关系进行了分析介绍，也介绍了采用溶剂化能关系得到溶质溶剂特性参数的方法步骤，并将这些参数用于萃取精馏萃取剂的选择与优化；也通过线性溶剂化能关系式建立无限稀释活度系数预测模型，取得了一定的预测精度；将通过上述方法初选的溶剂进行了常压汽液平衡的测定研究，通过实验研究选定含水4%的N-甲基吡咯烷酮溶液做为C5分离的萃取剂，测定了大量N-甲基吡咯烷酮与C5组分的二元平衡数据，并进行关联计算；以异戊二烯为目标产物在实验室规模的精馏塔内进行了C5分离的实验研究，取得大量塔内数据；通过选用合适的热力学模型，采用ASPEN中RadFrac模块对分离过程进行模拟研究，通过实验与模拟相结合，建立了C5分离的新工艺，为将来的工业化打下了坚实的基础。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

Not only community space that need to be made the person dulcify, what modern business space need also is exactly so a kind of atmosphere, in addition to vogue and spread, it even needs to express a kind of humanities concern and cultural atmosphere.

Integrated division takes an examination of Chinese Mount Everest the scientists of the team, was in a few days ago Mount Everest altitude 6520 meters east mouth of flannelette glacier strip of land between hills, build successfully removed observation of an automatic atmosphere to stand, this is the station of automatic atmosphere observation with the at present top height above sea level on the world.

中国健设完成全球高度最高，的自行天气观察站-观测站珠峰气象科考摘要：中国珠峰综合科考队的科学家们，日前在珠峰海拔6520米的东绒布冰川垭口，成功搭建起了一套自动气象观测站，这是目前世界上海拔最高的自动气象观测站。

Then we can solve the couple of atmosphere and temperature with fuzzy decouple control, and it is feasible to decouple by use of the functional relation of temperature, atmosphere and heat value.

对气氛与温度之间的耦合使用模糊解耦控制，利用温度、气氛和热值三者的函数关系式进行解耦是可行的，能达到良好的解耦效果，并进行计算机仿真，表明本文采用的智能解耦控制方案具有较好的控制效果。

This means the atmosphere arrived far later than expected. To confirm that comets contributed to the atmosphere, scientists will need to analyze the krypton and xenon isotope ratios in the cometary samples recently captured by NASA's Stardust mission, says geochemist and lead author Greg Holland, also at Manchester.

同样来自曼彻斯特大学的地球化学家、研究论文的第一作者格雷格·霍兰说，为了证实彗星促进了大气的形成，科学家们需要分析由美国航空航天管理局的"星尘"号航天行动最近获取的彗星样品，分析其中的氪和氙同位素比值。

Further analysis showed that lightning was closely related to graupel and ice in middle atmosphere (3.2~7km) and upper atmosphere. This result is consistent to the charge mechanism of lightning. Meanwhile, this study went through the sensitivity of WISCDYMM settings on thermal bubble condition of triggering cloud growth.
