平均距离

Integrating trellis-coded modulation with threaded algebraic space–time block code, trellis-coded modulation space-time block code is presented, which has the advantage of full-diversity and small detection delay. Based on TCM pre-processing, the minimum distance between different codeword matrixes of the TCMST block code is maximized, so the average bit error rate of the TCMST block code is lower than that of the TAST block code at the same signal noise ratio.

TCMST分组码具有满发送分集度和检测延迟小等优点；由于采用了TCM预处理，使得不同TCMST分组码码字矩阵间的最小距离达到了最大化，因此在相同信噪比情况下，TCMST分组码具有比TAST分组码更低的平均误比特率。

It was difficult for the aphid to take off at 8℃ and the flight time was shortened significantly.

在温度18℃时，麦长管蚜的平均飞行时间、飞行距离最大分别为3.101 h、3.676 km。

That indicated the availability of SRAP technique in studying genetic variability in Arachis. Estimates of genetic distance among the 28 accessions Arachis section ranged from 0.12 to 0.75 with average genetic distance of 0.42. A genetic distance clarified that A-genome A. duranensis was most closely associated with tetraploid germplasm, which could be A-genome donors. Dendrogram of cluster analysis classified 28 accessions Arachis section into two groups: one including tetraploid germplasm, and A.

聚类分析表明，28份花生材料间的遗传距离变幅为0.12~0.75，平均为0.42，A基因组物种Arachis duranensis与栽培种花生的亲缘关系最近，可能是栽培种花生的A基因组的供体。28份种质分为两大类，第一大类包含四倍体种质及A基因组的A。

The average deviation of required vehicles is 0.21, and the average deviation of distance percentage is 1.87%.

与文献已知最佳解比较，平均车辆数误差为0.21辆；距离误差为1.87%。

Most cyclists have a small computer on the bike that reports average speed, distances traveled and so on.

大多数骑自行车有一个小型的计算机上的自行车，报告的平均时速，距离旅行等。

The determination of its average velocity over this distance is not difficult.

要确定它在这段距离上的平均速度并不困难。

Average velocity may be defined as the distance traveled divided by the time of travel.

平均速度可定义为通过的距离除以运动所需的时间。

Average velocity may be defined as the distance traveled pided by the time of travel.

平均速度可定义为通过的距离除以运动所需的时间。

This site helps to calculate the average velocity over a givendistance.
