距离

Using "scale line" to represent the distance to help students understand the velocity concept, and discovery the major variable of velocity: distance and time.

以「距离数线」表徵长度量，帮助学生了解速度的初步概念，并透过数线的概念结构，帮助学生发现速率的概念与距离和时间两个变数有关。

Another influencing factor is the actual distance, as the velocity is computed as the ratio of the stipulated distance over racing time.

另一个影响因素是实际距离，因为速度=规定的距离÷比赛时间。

It includes options for vertical justification for nodes, collapsing of nodes, distance between sibling nodes and distance between non-sibling nodes.

它包括节点的垂直理由选择，崩溃的节点，节点之间的兄弟姐妹之间的非节点距离的距离。

In 1963 a Lancaster bomber crashed on Wallis Island, it was a remote place in the South Pacific , a long way west of Samoa .

1963年，一架兰开斯特轰炸机在瓦立斯岛坠毁，那是南太平洋的一个很偏僻的小岛，位于萨摩亚群岛以西，距离群岛还有很长一段距离。

With the increasing of distance from the injection side of profile control agents ,water saturation increases .It will decrease when the distance achieves a certain value ,and will approach the saturation of waterflood near the delivery end .

随着距调剖剂注入端距离的增加，水饱和度增加，达到一定距离后，水饱和度减小，在出口端附近，接近水驱时的饱和度。

Distance from withers to elbow and elbow to ground is equal.

从马肩隆到肘部的距离与从肘部到地面的距离相等。

Distance from elbow to withers is a little greater than from elbow to ground.

从肘部到肩上的距离稍长于从肘部到地面的距离。

Furthermore, the genetic distances in the HSL genes are much smaller between yak, cattle, and zebu than those between each of the three species and the buffalo. Therefore, it is reasonable to consider yak as an independent species of the genus Bos.

牦牛、普通牛和瘤牛3个物种间的遗传距离远小于它们各自与水牛这一物种的遗传距离，它们三者之间的亲缘关系也相对于它们各自与水牛间的亲缘关系都较近，故将牦牛、普通牛和瘤牛划分在同一个属——牛属更为合理。

It implies that the relationship between Japanese black cattle and Mongolian cattle is more distant. According to that the rate of sequence divergence of mtDNA is estimated to be 2% per million years, Haplotype II and III of mongolian cattle s mtDNA might be separate about 240 thousand years ago, which is earlier than the 10000-year history of cattle husbandry. Haplotype of yellow cattleand zebu cattle might be separate about 0.73-0.92 million years ago.

按照哺乳动物mtDNA碱基突变率每百万年2％计算，单倍型Ⅱ和Ⅲ(遗传距离为0.478％)所代表的蒙蒙古牛和日本和牛遗传多态性比较研究硕士学位论文古牛群体之间的分化时间大约24万年，这比人类驯化牛10000的历史要久远得多。I单倍型和11、m两种单倍型(遗传距离为1.467%，1.83870)所代表的牛群体之间的分化时间大约73万年至92万年前。

The result shows that firstly,zebu ismost closely related to cattle;secondly,closely related to yak,buffalo,pig,human,lastly,related to rat and mouse.The results of the phylogenetic trees reflect the molecularevolution relationship among these species,consistent with the zoological classification.The genetic distances among yak,cattle and zebu were relatively small,but geneticdistances between these three species and buffalo were relatively large.

研究表明，牦牛、普通牛和瘤牛三个物种间的遗传距离远小于它们各自与水牛这一物种的遗传距离，三者之间的亲缘关系也相对于它们与水牛间的亲缘关系较近，故将牦牛、普通牛和瘤牛划分在同一个属—牛属，而将水牛划分在另一个属更为合理。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
