In order to predict the whole process of bridge base settlements and make carve fitting,through a variety of theoretical calculations and a large amount of the settlement analysis of observed data statistical induction,the following index of the deformation process method is proposed first.

The investigation of deformation process and anomalous characteristics for arch dam and its abutments built on complex rock foundation;

The deformation process of tube cold rolling on double-set multi-roll mill is studied and the calculation formulation of deformation for once roll,elongation coefficient, relative reduction of wall thickness per rolling schedule are deduced.

The deformation process of strips trimming is introduced.

And pricing process respectively driven by an exponential of a Levy process, we obtain the accurate formulas of European option.

This paper considers the affection about exchange rate to the price of options, supposes that exchange rate and pricing process respectively driven by an exponential of a Levy process, uses an actuarial approach and some important quality of Levy process, and obtains pricing formula of European option on foreign equity options.
