查询词典 difference frequency

A deletionof T base pair was detected at 7bp in intron 1 of sheep TNNC2 gene,which was named allele D.The frequency of allele D deleted was 0.78,0.77 and 0.71 in Small-tailed Han sheep,Tan sheep and Inner Mongolia sheep,respectively,and thedistribution of gene and genotype were no significant difference among the three sheeppopulations by X~2 test(p＞0.05).The association analysis between the genotypes and meatquality traits indicated the genotypes significantly influenced sheep meat quality.

在供试绵羊群体中检测到TNNC2基因第一内含子第7bp处一个T碱基缺失，并命名为D等位基因。D等位基因在供试的小尾寒羊、滩羊及蒙古羊群体中频率分别为：0.78、0.77和0.71.x~2检验表明，该位点基因及基因型频率在小尾寒羊、滩羊和蒙古羊试验群体中差异不显著(P＞0.05)。

The authors analyze the operation characteristic of distance protection of transmission line connecting wind farm with power grid under the variation of parameters such as the amplitude ratio of electromotive force at both sides, the phase difference of electromotive force at both sides, equivalent impedance of sources, system frequency and so on; based on the real-time current and electromotive force at wind farm side as well as the information of wind power generators participating power generation, a method to adaptively set the operation boundary of distance protection by use of the information at wind farm side only is proposed.

文章分析了风电场和电网联络线的距离保护随电源电势幅值比、电势相位差、电源等效阻抗、系统频率等参数变化时的动作特性，并基于风电场侧的实时电流和电势与参与发电的发电机信息，提出了仅利用风电场侧信息量自适应整定保护动作边界的方法。
