function incision(Result,start,over){
        Result=Result.substr(Result.indexOf(start));
        if(over!=""&&over!=null&over!=undefined){
            Result=Result.substr(0,Result.indexOf(over));
        /**alert("后"+strResult);**/
           Result=Result.split(start)[1];
        }
        else{
           
            Result=Result.substr(Result.indexOf(start)+start.length);
    /*alert("后"+Result);*/
           
        }
