摘要： A ski has an elongated body part, a polyethylene bottom layer arranged on the body part, and a roughening provided on a sliding surface of the bottom layer over a supporting length of the ski and including a plurality of projections each formed as an elongated tooth from polyethylene of the bottom layer and inclined in its entirety toward the rear end of the body part, wherein the teeth are arranged with a density of between 1000 and 4000 teeth per cm.sup.2. The inventive ski is manufactured by dry grinding of the sliding surface of the polyethylene bottom layer with a relatively high efficiency.
摘要翻译：滑雪具有细长的主体部分，布置在主体部分上的聚乙烯底层，以及设置在滑雪板的支撑长度上的底层的滑动表面上的粗糙化，并且包括多个突起，每个突起形成为细长齿聚乙烯，并且整体朝向主体部分的后端倾斜，其中齿的密度以每平方厘米1000至4000个齿之间的密度布置。本发明的滑雪板是通过以较高的效率对聚乙烯底层的滑动表面进行干式磨削来制造的。

摘要： A tennis racket includes a handle portion, a frame portion which has strings mounted therein and a throat portion which connects the handle portion and the frame portion. An insert is installed in the throat portion and connected to the same. The insert is adapted to have secured thereto at least some of the strings. The insert may undergo elastic yielding in direction substantially normal to the general plane of the frame portion in response to the impact of a ball onto the strings and consequent transmission of the impact stress from the strings to the insert.
摘要翻译：网球拍包括把手部分，其中安装有琴弦的框架部分和连接手柄部分和框架部分的喉部分。插入件安装在喉部并连接到喉部。插入件适于固定至少一些串。响应于球对琴弦的冲击并且随后将冲击应力从琴弦传递到插入件，插入件可以基本上垂直于框架部分的总平面的方向经历弹性屈服。
