Subclasses performace.

Within-subject comparison of the Kappa scores associated with the subclasses of the change-speed class (e.g. 1 → 2 represents the class where the speed changes from 1 to 2 Km/h). Non significant Kappa scores are marked with *.Subclasses performace.针对变速类别（change-speed class）下各子类对应的科恩Kappa系数（Kappa score）进行受试者内比较（例如，1→2代表速度由1千米/小时变化至2千米/小时的类别）。无统计学显著性的科恩Kappa系数以*标记。子类性能分析。
