球与拍面接触时.使拍面海绵或胶粒变形而吸收球的动能.在弹性体恢复变形时使球受弹力f1.弹力f1的方向与来球方向有关:当来球不是垂直撞击拍面时,与球接触的胶粒或海绵的压力分布将不同于垂直撞击拍面时的压力分布,所以,球受到的弹力f1 (各受压胶粒或海绵小单位的合力)的方向将随来球方向而改变,弹力f1的大小将随胶粒的分布不同而不同.
Google翻译的可不行!

球与拍面接触时.使拍面海绵或胶粒变形而吸收球的动能.
When the ball is in contact with the racket,visco-elastic material or rubber particles of racket surface deforms and hence energy is absorbed from the ball.
在弹性体恢复变形时使球受弹力f1.
Instant recovery of its shape from a deformation resulting from ball-racket contact will impose a reactive force ,f1 to the ball.
弹力f1的方向与来球方向有关:当来球不是垂直撞击拍面时,与球接触的胶粒或海绵的压力分布将不同于垂直撞击拍面时的压力分布,所以,球受到的弹力f1 (各受压胶粒或海绵小单位的合力)的方向将随来球方向而改变,弹力f1的大小将随胶粒的分布不同而不同.
Vector and magnitude of reactive force F1 responds to direction of the ball movement.There's a significant difference between pressure distribion on racket surface (where the rubber particles or sponge come in contact with the ball) of a vertical racket-ball contact and that of a non-vertical racket-ball contact.Therefore,vector of reactive force f1 (with a combined force experienced by the rubber particles or sponge particle) will change according to direction of the ball movement.Magnitude of reactive force,f1 will vary according to distribution pattern of rubber particles on racket surface.
呵呵,我公司可以翻译的

Contact with the ball when shooting. So take a sponge or rubber surface deformation and to absorb the kinetic energy of the ball. Elastic deformation in the restoration of the ball by elastic when f1. F1 stretch to the direction and the direction of the ball: When to shoot the ball rather than hit the vertical surface when the particles come into contact with the ball or sponge the pressure distribution will be different from the vertical impact surface film pressure distribution at the time, so the elastic ball by f1 (the compression sponge particles or small units of force) as to the direction of the ball changes direction, will stretch the size of f1 with the distribution of particles vary.

The ball with the racket's face. Make contact racket face sponge or granule deformation and absorption of the ball. When the deformation in the elastomer recovery by elastic f1 ball. Elastic f1 direction and the direction of the ball on to the ball is not perpendicular when to hit the ball with the racket's face, the contact pressure distribution of colloidal particle or sponge different impact on vertical racket face when the pressure distribution, so that the ball under the pressurized elastic f1 (colloidal particle or sponge smaller unit of the direction will come with) and change the direction of the ball will bounce, the size of the f1 with both the distribution and different.

Ball with clap noodles contact.make to clap noodles sponge or gum grain transform but absorb ball of kinetic energy.At flexibility body the instauration transform make the ball be subjected to elasticity f 1.Elasticity f one direction has something to do with coming to ball direction:When come to ball isn't perpendicular to bump shot to clap noodles, with ball contact of gum grain or the pressure of sponge distribute will differ from perpendicular bump shot to clap noodles of the pressure distribute, so, the ball be subjected to of elasticity f 1(each is pressed gum grain or the sponge small unit of cooperate) direction will with come to ball direction but change, elasticity f 1 sizes will with distribute of gum grain dissimilarity but dissimilarity.
