查询词典 percent error

The optimal pH of xylanases was calculated based on the model and the results was shown as below: there were only two xylanses with the deviation between the calculated pHs the optimum pHs larger than 0.6, while there 6 xylanases with the deviation less than 0.1 the mean absolute percent error was 5.91%, the mean absolute error were 0.26 pH unit, respectively. It was superior when compared with the reported stepwise regression model based on dipeptide composition.

利用该方程，计算各木聚糖酶的pH值，结果表明，仅有2个木聚糖酶的最适合pH计算值与实测值相差大于0.6，而有6个木聚糖酶最适pH计算值与测定值相差小于0.1，平均绝对百分比误差为5.91%，平均绝对误差为0.26个pH单位，所得结果优于用二肽进行逐步回归所得模型的结果。
