Also, a rough sinusoidal pattern can be seen in plotting average daily temperatures for each day of the year, although the graph may resemble an inverted cosine wave.

此外，一个粗略的正弦曲线图表可以在每天或每年的平均每日温度平面图表中看到，虽然这个图形可能和倒置的余弦波看起来很像。

Taking advantage of the analysis of the bias, an unbiased correlator without multiplier is deduced for Gaussian process and sinusoidal wave with random phase.

利用偏差分析的结果，可以得出一个对正态过程和随机相位正弦波都是无偏的不用乘法器的相关器。
