5.This paper presents the parameter selection and design method of saturant reactor for the start of high-voltage ac motor. The concrete example is given.
6.Finally, a mechanism of AC etching for aluminum foil in HCl and a theoretical rule for choosing electroetching conditions were suggested on the results.
7.The magnetooptic self-nulled ellipsometer,with ac Farady magnetooptic modulating and phase locking to detect nulled point,has the high abilities of prevent interference and angular recognize.
