JIANG Juncheng HE Longde (Institute of Mechanics, Chinese Academy of Sciences, Beijing 100080, China)  
The effects of the shapes and dimensions of table tennis bat on table tennis ball head on impact probability have been investigated by an analytical method of probability function.In view of the fact that the table tennis bat outline is a curve of the equivalent probability,this paper derives a mathematical expression for the outline of the table tennis bat that gives the maximum impact ball probability. The results indicate that the present shapes and dimensions of the table tennis bat need to be improved further in order to reduce muffs and to obtain the maximum head on impact ball probability.
