Based on the capability of moving objects,a interzone-time algorithm and a critical algorithm are presented.

In the BKPLS,the batch-wise method in the KPLS is transformed into a block-wise method based on the symmetric character of kernel matrix,so that it relaxes the requirement on computer hardware and decreases calculation time.

The influent factors on calculating time and convergence stability of solution to hot rolling by finite element method are investigated.

With the aim of keeping the calculation accuracy unchanged and shortening calculating time,the influence of initial velocity field on calculating time and calculated results were discussed,where the initial velocity field was set differently by the primary,G function or improved refined mesh methods.

The first weakness is that it cannot make the achieved discrimination vectors completely satisfy the statistical uncorrelation while costing a minimum of computing time.

Comparison with traditional algorithm was implemented through computer simulation,which demonstrates computation time of program can be reduced efficiently by employing this new algorithm which can be flexibly applied in all kinds of high order FIR filter designs in real-time field.
