摘要
踝关节是人体重要的负重关节,踝关节外侧韧带损伤是常见的运动损伤之一,严重影响人们日常生活质量,早期预防具有重要意义.踝关节外侧韧带损伤的概念和存在的描述是不确定的,这种不确定性一表现在损伤概念与定义中被忽略的模糊性,二表现在描述损伤存在与发生时被忽略的随机性.分析了损伤变量的模糊性和随机性二者在[0,1]区间上的一致性,基于损伤变量的广义非确定性提出了模糊随机损伤模型.
The ankle jiont is the important loading joint for human, the injury of lateral ligament of the ankle is one of the most ordinary injuries, which affects our quality of daily life, it＇s dubious to describe the concept and existence of injury of ankle lateral ligament, firstly, the fuzziness is neglected in the concept and definition of injury, secondly, the randomicity is neglected to describe existence and happening of injury. The author analyzed the coherence about injury variable fuzziness and randomicity in [0,1], the fuzzy stochastic injury model was established based on injury variable generalized uncertainness.
