Research on die-surface-modification method based on compensation of geometric spring back value;

Regarded steel bridge piers with box sections as numerical analysis object,using a modified two curved-surface model,the isotropic hardening model and kinematic hardening model,the hysteretic behaviors of steel bridge piers under positive and negative cyclic load were analyzed.

Then select 100 listed companys\'date for sample from Shanghai Stock Exchange and do the empirical analysis by the Modified Cross Selectional Jones Model,demonstrated the new accounting standards than the old one on the management of the overall surplus superior to the conclusion.

The current major application fields of satellite positioning some of tropospheric refraction correction model are introduced.

A new correction model for the target deviation is deduced when the optical axis is not parallel to the collimating axis, and the coordinates of the camera projection center in measuring coordinate systems are calculated in conditions of the mismatching between the optical center and the theodolite rotation center by using the object focus optical system as the projective center of camera system.

A profit distribution correction model for EPC engineering supply chain based on Shapley value was proposed which makes the profit distribution more reasonable.
