摘要：
A tennis racket is made lighter than conventional tennis rackets yet has a higher center of percussion and a higher frequency of vibration. The head of the racket is ovoid, and the widest part of the head is above the longitudinal midpoint of the head. The longitudinal strings are fan-shaped and diverge outwardly and upwardly from the bottom of the head.
