The paper discusses the general methods of information source by web disk,introduces the method of changing the CD tower to disk array server,and analyzes the advantages of the disk array server relative to the CD tower.

This paper have introduced the mirror of compact disk server, and compared with CD tower and CDROM database at all round.

Study on and Discussion about Heat Conduction Capability of SiC Tray due to ZnO Agglomeration;

Improvement of dead trays in rectifying tower kettle for butadiene extraction;

Controlling of the vertical alignment of tower and the level of tray;

New technology and new equipment such as high efficiency column tray are used.

Investigation was made to improve the flow of liquid in industrial tray column on the basis of understanding the cause of nonuniform flow on the column tray.

The brief comments on the representative techniques,such as novel packing,liquid distributor,vapor initial distributor,vapor redistributing plate,main beam and novel column tray,were presented.

Manufacture and application of the flat interface tray of zinc rectifying furnaces;

By using new technology of energy saving and consume reducing, such as water heating agent, high speed electrostatic desalting, CTST tray, surface evaporator, corrugated pipe heat exchanger, high temperature infrared fluid emulsified material etc.
