A series of non parametric tests validated the digitized distortion model and indicated that the Paired Comparison Method was superior to the Standard Comparison Method.
结果一系列非参数检验证实数字变形模型的有效性，且配对比较法优于普通的标准比较法。

Sine signals used as standard signal, sine signal requirements must be more precision, stability and low distortion rate.
正弦信号用作标准信号时，要求正弦信号必须有较高的精度、稳定度及较低的失真率。

Now it is possible to see with superior quality without the intense heat, excessive glare and harsh distortion of standard lighting.
