Since it is a range predicate and there are no frequency and histogram statistics available, the filter factor is calculated with the basic statistics information HIGH2KEY and LOW2KEY.
由于它是范围谓词，而且没有频度和直方图统计数据可用，过滤因子是用基础统计信息HIGH2KEY和LOW2KEY计算得出的。
Notice the odd roughness of the dense histogram in the region around 7-12 degrees, with both very high frequency of some measurements and unexpectedly low frequencies of others.
注意，在稠密直方图中 7-12 度附近出现了偶然性的不平滑，有一些温度频率非常高， 也有一些频率出人意料地低。
Statistics histogram data processing scheme is designed. Standard deviation of frequency modulation is found out according to normal distribution characteristics.
设计了统计直方图数据处理方案，按照正态分布的特性找出了寄生频率调制的标准偏差。
