However,the infor- mation distortion which comes into being at every links of imparting-process and is not only influenced but also restrict- ed by different elements brings forward passive effect to the choosing,appoint and management of cadres.

With massive measured data of the river-crossing trigonometric leveling survey,the change rule of atmospheric refraction coefficient is calculated and analyzed in elevation transmission region of a bridge,and some beneficial conclusions are obtained.

Study of the influence of transport process on removal in SO_2/NO_x/Hg by activated carbon fibers;

Theoretical Analysis on Transport Processes in PEMFC;

A basic equation group and its analytic solution on transfer process in TIEC;

A transfer axiom is proposed, which declares that any form of transfer process is driven by the difference of the corresponding basic intensive property, and the transfer of basic extensive property in the process must be accompanied with the corresponding energy and exergy.

Based on the viewpoint of contradiction and unification,the approaches to enhancing heat and mass transfer as well as to optimizing and designing transfer process systems are reviewed,and the contradiction between the decrease of energy destruction and the enhancement of transfer process are analyzed.

Three elevation transferring methods, which are hanging steel ruler, GPS and upright measuring elevation with total station.
