1·The Maximum permissible error when the working frequency of Resistor is equal to or lower than the measurement frequency.

电阻箱的工作频率等于或低于测试频率上限时的最大允许误差。

2·Experimental results and theoretical analysis has proved the feasibility because of less permissible error of data caused by the embedding of watermarking.

水印嵌入引起的数据误差较小，算法具有较好的可行性。

3·Results from this study indicate that direct verification of the Newton second law could be achieved satisfactorily within the permissible range of error.

结果表明，在实验误差允许的范围内牛顿第二定律均能得到较好地直接验证。

4·Compared with the measured values, the error of the calculation results by computer is Within the engineering permissible range.
