What is called a repeating number ? study page 28 by yourself 什么叫循环节?自学第28页。
And repeat number in one section in first test had better more than 10 建议初次试验组内重复次数不宜少于10次。
A simple program that generates non repeating numbers at random in certain ranges 这个程序可以生成一定范围内不重复的随机数字。
Determining the optimum repeat number is always a great concern of field test 摘要确定适宜的试验重复次数一直是野外试验关注的问题。
No repeat - a simple program that generates non repeating numbers at random in certain ranges 这个程序可以生成一定范围内不重复的随机数字。
The computer stochastic simulation test was used to study repeat number for controlling the probability of type ii errors and establish a formula calculating sample size in the ease of known historical data 利用计算机摸拟试验,从控制犯第二类错误的概率来研究两总体均值比较试验时的重复次数问题,求得在已知历史资料情况下样本容量的计算公式。
Results 1 . denomination and classification of y - str loci allele samples of sequenced alleles were used as standards , mixing their pcr products to make the allele ladder . different y - str loci alleles were denominated by their repeats numbers , which were detected by sequencing 待测样品和ladder同步加样进行聚丙烯醚胺凝胶电泳,谱带相互比较进行待测样品的分型和命名,各y ? str位点的等位基因标准品测序结果参见图1 1 1 7 。
Firstly , let me introduce the features of this cell . adapted such method to give birth to energy as zinc granules reation with o2 of air , this cell possesses the virture that there is a good relationship between discharging energy and charging energy , which is testified by the test of meters from company and actual experiments . meanwhile , repeat number of charging can be ignored for cell because it get energy again by substituting substance in fuel cell . so , we can get the conclusion that this cell belongs to such type as whose energy rebirthes without history factor which always influnences other types of cells . from the above analysises , it will be easy to get some solution to detect energy of zinc / air fuel cell in related precision 该公司生产的锌空电池与传统的充电电池有着完全不同的特点。首先,它采用锌粉在反应液中与空气的氧气反应产生电量,经过测试(包括出厂参数测试、现场测试和实验测试) ,电池的放出电量与充入电量有着对使用非常有利的某种关系特点;其次,它采用更换反应液的方式来重新得到电量,这样就使得充电的重复率可不作为电池放电的因素。该锌空电池属于电量可重复植入,但没有产生影响电池放电的传统参数?历史充放电效果因素。
