在1983年9月的慕尼黑国际体育用品博览会上,英国一家工厂生产的一种新型网球拍,深受参观者的欢迎。这种新型的网球拍,是用碳纤维材料制成。与传统的同类产品相比,其头部框架的构造与众大不相同。众所周知,传统的网球拍头部框架是一个闭合的椭圆形。而这种新型球拍的头部框架,则是一个非闭合椭圆形;在它与把柄的连接处,开了一个缺口。其目的是阻止球拍网的反复振动沿着球拍的柄传至运动员的手臂。这种新型球拍,可以有效地防止运动员在比赛场上损伤肘关节。因此被誉为“网球场上无痛苦”球拍。
At the September 1983 Munich International Sporting Goods Fair, a new type of tennis racquets produced at a British factory was well received by visitors. This new type of tennis rackets is made of carbon fiber material. Compared with the traditional similar products, the structure of the head frame and vastly different. As we all know, the traditional tennis racket head frame is a closed oval. The head frame of this new racquet is a non-closed oval; it opens a notch at the connection to the handle. Its purpose is to prevent the racquet from repeatedly vibrating along the racquet’s handle to the athlete’s arm. This new type of racket, can effectively prevent athletes from damaging the elbow in the playing field. So hailed as “tennis court painless” racket.
