Because this activity is closer to the device drivers than to the higher-layer protocols and features, we will not spend much time on it.
因为比起上层的高层协议和特性而言，这些确实更贴近设备驱动一些，因此我们将不会花太的时间在这上面。
The accuracy of the product activity cost will certainly decrease in the combination after which the amount of the final cost drivers is smaller than the rank of the coefficient matrix.
导致最终成本动因个数小于系数矩阵秩的合并必然损失产品作业成本的精确性。
