Avoid sulfation for ordinary batteries, if they are in an overcharging mode or undercharging mode for a longtime, it will make the battery lose its internal water and lead to sulfation, thus greatly shortening charger's operating lifetime. But can solve batteries' problem of imbalance derived from longtime overcharging and undercharging, thus avoiding internal sulfation of the battery, restoring batteries' capacity and extending their operating lifetime.

避免硫酸盐化--普通电池如果长期处在一种过充电或欠充电状态中，会使电池内部不断失水和硫酸盐化，这样就会大大缩短充电器使用寿命，可是，它能解决电池长期过充电和欠充电引起的失衡，避免电池内部硫酸盐化，能够恢复电池容量，从而延长它的使用寿命。

This research method is to use the three-dimensional mapping software to draw the cardiovascular stent of different size first , next is it create their cardiovascular stent boundary conditions and simulation their of support after implantation according to finite element method into the human body to go; Receive different residue pressures and pressure of the repeated blood circulation , greatest stress , meets an emergency and the relation between total deformation amount caused; Being imitated the cardiovascular stent , the position with damage of fatigue life in the blood vessel by its greatest stress value at the same time ; But by the simulation result of the above , can understand that use life of Palmaz-schatz cardiovascular stent has been more than 109 up till now ; At the same time , can know the position where the stress two times concentrates , the right angle position joined in the rib and rib of Palmaz-schatz cardiovascular stent too.
