Based on the parameters Peak, Torque and Work for each repetition, indices of absolute (KADabs) and relative (KADrel) strength-endurance were derived. KADabs was calculated as the mean value of all testing repetitions, KADrel was determined in two ways: on the one hand, as the percentage ...
a所谓绝对误差是指测量值与被测量真值之间的差值,但是由于绝对误差不能确切地反应出测量的准确度,所以很少用此误差来分析数据,而引用误差实际上也是一种相对误差,只是将相对误差计算时分母由实际值换成测量误差的上限即可,也就是说引用误差是绝对误差与被测量范围上限之比 The so-called absolute error is refers to...
