网球技术的变化。阿加西曾说“现在的球弦，你可以全力猛击同时还保持控制”。有空的话可以再聊聊这个话题。
另外，现在最广泛使用的材料不是“钛合金”，而是以石墨为主的碳素复合物。并且，一些厂家已经着眼于下一代球拍材料了。
What's next? How about an electronic racquet? Head has come out with a racquet that uses piezoelectric technology. Piezoelectric materials convert vibration or motion to and from electrical energy. Head's new racquet takes the vibration resulting from impact with the ball and converts it to electrical energy, which serves to dampen that vibration. A circuit board in the racquet's handle then amplifies that electrical energy and sends it back to the piezoelectric ceramic composites in the frame, causing those materials to stiffen.
