Discussion on relationship between quantity of transfer water and pricinple of ionic membrane;

It indicated that Austenitic can transfer to Martensite partly because of stretching deforma- tion,which increases migration quantity of heavy metal in return.

According to requirement of national standard to heavy metal migration quantity of stainless steel household utensils,this paper analyzed the effect of different welding on migration quantity of detected element based theory of corrosion and diffusing.

By Application of the V\|F\|B model which is obtained by combining the Vasquez\|Flint (V\|F) model for donor\|acceptor energy transfer and the model of Burshtein for donor\|donor energy migration, the experimental luminescence decay curves of 4S 3/2 state of Er 3+ in LaF\-3 at 295K for four different concentrations are re\|simulated successfully.

With the help of I H model and Y T model, the luminescence decay curve of 3H 4 of Tm 3+ was fitted, and the fitted values of corresponding energy transfer interaction parameter C DA and energy migration interaction parameter C DD were calculated.
