According to the experimental data,using the best square approach way,the linear extent magnetostriction properties equation of Terfenol-D material is made,then the magnetostriction properties equation under a unconstant preloading is educed.

For a given power network model,once establishing initialization pheromone matrix,searching the path depending on the special ability of ant colony,combining with an improved method of refreshing pheromone,Manhattan distance and the thought of flexibility,the best power distribution network planning path is found at a higher rate only if it exits.
