分组频率

群频率

gene frequency───[遗]基因频率；等位基因频率

increased frequency───提高频率

expected frequency───期望次数；期望频数

allele frequency───n.等位基因频率

angular frequency───[物]角频率

audio frequency───[声][通信]音频；成音频率

gyrofrequency───n.[电磁]旋转频率；回旋频率

low frequency───低频率；低周波

natural frequency───[物]自然频率，[电子][物]固有频率；本盏率

The team then tabulated the frequency of wars and grouped them into three classes: very high (more than 30 wars per decade), high (15 to 30 wars per decade), and low (fewer than 15 wars per decade.)───然后，研究小组将战争爆发的频率列表，并分为三类：异常高发期(每十年多于30次)，高发期(每十年15至30次)和低发期(每十年少于15次)。

For example, Web-access statistics (as currently compiled) are little more than frequency counts grouped in various ways.───例如，Web访问统计信息(按当前所编辑的)只不过是以各种方式进行分组的频率计数。

The Six Sigma Black Belt should be able to compute the mean and standard deviation from a grouped frequency distribution.───六西格玛黑带应该能够计算出一个分组发生频次分布数据的均值和标准偏差。

The Six Sigma Black Belt should be able to compute the mean and standard deviation from a grouped frequency distribution.───西格玛黑带应能从一组频次分布数据计算出均值和标准偏差。
