Commenting over the come across, snake expert Robert Henderson, from your milwaukee Museum of Natural historical past, explained: "Around the globe new species of frogs are increasingly being identified and explained quite frequently."

是一组数据的总和除以数据的个数得到的值。它反映了数据的中心位置或平均水平。计算公式：

extension is to permit us to consider any established as domain or codomain of the purpose. 来自 Cambridge English Corpus 示例中的观点不代表剑桥词典编辑、剑桥大学出版社和其许可证颁发者的观点。

Most engineers are so properly-versed in carrying out this that it may look, to your uninitiated, that there is no theory guiding it. I obtained this from your Internet: -

有效值/均方根值是对数据的平方和取平均再开方所计算出来的值。所以通常情况下采用的计算方法是：将所有值平方求和，求其均值，再开平方，就得到均方根值。C 代码如下：

These cats show numerous coat designs, from spots to stripes, typically tailored to their distinct habitats. Their dimension is modest to medium, and they've got developed to hunt several prey, from compact rodents to arboreal mammals, according to the species.

At any given time when natural record was a important Instrument for discovery, Merian identified specifics about vegetation and Insects that were not Earlier known.

家庭用電源を始めとして、この実効値は電気の世界では本当に良くでてきますから、正しく理解して電気についての知識を深めていきたいですね！

在直流电路中，欧姆定律表达式为 I = V R I = frac V R I=RV​ ，由此可推出 V = I R V = IR V=IR 。功率公式为 P = V I P = VI P=VI ，将 V = I R V = IR V=IR 代入功率公式可得 P = I two R P = I^ 2 R P=I2R ；若将 I = V R I = frac V R I=RV​ 代入 P = V I P click now = VI P=VI ，则得到 P = V two R P = frac V^ 2 R P=RV2​ 。这些公式在已知直流电压 V V V 、电流 I I I 和电阻 R R R 中的任意两个量时，能准确计算出电路消耗的功率。
