There are complex variations in realistic low-voltage power line network topology framework.In order to study the low-voltage power line transmission channel model,a model to describe the power line network channel topology framework is established in terms of basic characteristics of low-voltage power line network in this paper.

低压电力线网络拓扑结构变化复杂，为了研究低压电力线信道传输模型，根据低压电力线网络的基本特点建立了描述电力线网络拓扑结构的模型，利用模型把低压电力信道作为一个过程去描述，建立了节点信号传输函数来推导低压电力线网络的传递函数。

There were three isozyme (AMY1, AMY2 and AMY3) at the locus of amylase in Qinghai Merino, moreover, there were two genotypes of AMY2A and AMY2O at the AMY2. Monomorphism was tested at the locus of AMY in Gansu Alpine Merino. The degree of genetic variability estimated by Nei's expected average heterozygosity for the 6 blood protein loci was relatively higher in Gansu Alpine Merino and in Qinghai Merino than that in others, which indicated that there are higher genetic variations and richer genetic diversity in Alpine Merino.

从6个血液蛋白位点的Nei氏预期平均基因杂合度所估计的群体内的遗传变异以及与本研究其它群体的结果相比来看，甘肃高山细毛羊和青海细毛羊的群体内的遗传变异相对较大，而其它群体内的遗传变异则相对较小，说明高原型细毛羊群体内遗传变异程度较大，遗传多样性较丰富，具有较大的选择潜力，为高原型细毛羊进一步选育提高提供了遗传基础。

Since the 1940s when Ashley Montagu argued against the use of the term "race" in science, a growing number of scholars in many disciplines have declared that the real meaning of race in American society has to do with social realities, quite distinct from physical variations in the human species.

自从二十世纪四十年代阿舍雷·蒙太古提出反对在科学领域使用"种族"这一术语以来，许多来自不同知识领域的学者都声明在美国社会中种族的真正涵义和社会现实没有关系，并且应区别于自然科学意义上的"多样的人类种群"。

"Moony" creates a mystic space by using a steam screens with organic variations and interactive butterfly images.
