对乒乓球技战术信息分类,按照面分类法对球技术动作分类;按照线分类法对战术信息分类。在分类基础上给出各种动作和战术类的编码方案。基于上述编码体系给出三种数据采集方案,经测试三种方案均可作为采集方法实际使用,但从速度和方便角度,第二种和第三种更好一些。第二种方法的记忆强度为45(相当40个符号的记忆量),第三种方法的记忆强度为45,经测试在短时间(20 h)内完全可以熟练掌握采集方法。
The classification of tactical and tactical information of table tennis, according to the surface classification of ball technology action classification; according to the line classification of tactical information classification. On the basis of the classification given a variety of action and tactical coding scheme. Based on the above coding system, three data acquisition schemes are given. The three schemes tested can all be used as actual acquisition methods. However, the second and third schemes are better in terms of speed and convenience. The second method has a memory strength of 45 (which is equivalent to 40 symbols of memory) and the third method has a memory strength of 45 which has been tested to be sufficiently familiar with acquisition methods in a short period of time (20 h).
