The study of the protosepta number, the yielding position and fashion, the arranging system of Heterocorall septa is basic premise in discussing the origin, evolution and classification of Heterocorall.

Chinese scientists have gotten outstanding achievement in the classification, microstructure and septal evolution of the heterocoral.

Since the discoverv of new heterocoral with 3 septa,the septal variety ofthe different genera of heterocorals has been clearly revealed.

A laboratory scale dividing wall column(DWC) was built for separating a mixture consisting of ethanol/n-butanol/hexanol in order to study the characteristics of the DWC.

This paper introduces the design principle of heat insulation wall for the aluminum alloy car body,calculates the vehicle s average heat transfer coefficient value by classifying the car body into 15 areas,and confirms the predicted value through experiment.
