查询词典 arithmetic average deviation

An improved scheduling method based on exponential division of deadline is presented after study on the problem of prevenient average division of deadline method in this paper.The paper also proves when the relative deadline of each node is too large,the schedular performance of messages transmission task using average division of deadline will be decreased by introducing notion of quantization cost.The new method solves the problem well,and digital simulation validate the new method.

摘 要：针对平均分区的EDF算法在CAN总线中的应用出现的问题，本文提出了一种改进的基于指数分区的EDF算法，并通过引入量化误差的概念，推导证明当CAN网络中各节点相对截至期分布时间过大时，平均分区的EDF算法会导致CAN总线中信息传输任务可调度性的下降，而基于指数分区的EDF算法保证了信息传输任务的实时性，仿真试验验证了算法的有效性。

The experiment of tagging and releasing Sparus macrocephalus was carried out in 2004, 2005 and 2006 using three tagging methods of coded wire tag, visible implant elastomer tag and scutcheon tag respectively in the Zhoushan sea area. In 3 years, 17616 Sparus macrocephalus with average body length of 131.9 mm and average body weight of 46.46 g were tagged and released.

The XRD analysis revealed that the relative pure nickel metal products with an average size of 12.6 nm could be obtained using PVA as surfactant, a mixture of nickel and nickel sesquioxide products with an average size of 25 nm was obtained using DTAB as surfactant.

结果表明：以PVA作表面活性剂得到相对纯的纳米镍粉，平均粒径约为12.6nm；而以DTAB为表面活性剂得到镍和三氧化二镍的混合物，平均粒径约为25nm；采用PVA为表面活性剂在产品的纯度和粒度上都优于DTAB。

The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。

Results: Average protein spots were 426 in the diarrhoea-predominant IBS group by using Coomassie brilliant blue staining, while the constipation-dominant IBS group by using silver staining got average 581 protein sptos.

结果：考马斯亮蓝法染色用于腹泻型IBS患者，平均得到蛋白质点426个；硝酸银染色法用于便秘型IBS患者，平均得到蛋白点581个。

Just as the average tax payer would probably commit more mathematical errors if he were to try to use a computer to complete his income tax return, the average logger misuses, and frequently abuses, the equipment he purchases (for example, drives a skidder with two flat tires, doesn't change the oil filter).

就像一般的纳税人会更容易承认数学上的错误一样，如果他尝试用电脑完成他的个人所得税返还表的话。如果伐木者更普遍地误用，更经常地滥用那些他买的工具比如说，用两个扁的轮胎驾驶一个集材机，却不改变机油滤清器。

The results were as follows: After the slash pine stands cover-overheaded, the average DBH and crown diameter are very negative correlative to stand density, the average high of branch and high of tree are a certain extent correlative to stand density; high stand density can be a certain extent accelerate high growth, but the effect is limited.

结果表明：湿地松人工林林分郁闭后，林木平均胸径、平均冠幅与密度呈极显著负相关；林分平均枝下高、平均树高与密度有一定程度的相关性，高密度一定程度上可以促进林木的高生长。
