  • Microsatellite dna is among the most efficient class of molecular markers due to their hyper - variable and co - dominant nature with relatively high abundance and random distribution in the genome , and have been applied to a variety of fields including population differentiation , kinship analysis , linkage analysis , and evolutional and ecological studies
    摘要微卫星dna由于具有高度多态性、共显性遗传、基因组中含量丰富且随机分布等特点,目前已成为最有效的分子标记之一,并应用于种群分化研究、血缘分析、基因连锁分析、进化以及生态学研究等许多领域。
  • The mean and the mean square error of the difference between the scattering field and the cancellation field are calculated . the probability of the cancelled effect under the given errors is also computed in the cases that the azimuth angle varies with the law of uniform and random distribution , respectively
    此外,还对被保护目标散射场的对消效应作了统计分析,计算了对消场和散射场误差的均值和均方差,并在方位角以均匀和随机规律变化时给出了它们在给定误差值下存在的概率。
  • As examples , heterogeneous anisotropic fractured rocks of which the autocorrelation functions of crack number density can be described as 2 - dimensional exponential ellipsoidal or gaussian function were simulated especially . the results show that : 1 ) the random distribution characters could be different for different elastic constants under the same random distribution of crack number density . 2 ) the exponential ellipsoidal heterogeneous anisotropic random fractured model could be a suitable model for the multi - scaled and self - similar heterogeneous media
    模拟结果表明: 1 )弹性常数的分布特征与裂纹数密度的分布特征不相同,并且裂纹数密度对不同的弹性常数有不同程度的影响; 2 )指数椭圆型随机裂缝模型适用于模拟具有多尺度、自相似的特性非均匀裂缝岩石; 3 ) gaussian型随机裂缝模型适用于模拟单尺度、平滑的非均匀裂缝岩石。
  • It was shown that in most cases p . euphratica appeared to have an aggregative distribution at different distances away from the river but it tended to be diffusive , appearing to have an random distribution ; in the two cross sections , p . euphratica tended to increase its distribution pattern scale and aggregation intensity as the distances increased and the distribution pattern scale of p . euphratica in kaerdayi cross - section was lower than that in yingsu cross - section at the same distances away from the river , which was because the cross sections had different underground water conditions and topographical conditions
    结果表明:胡杨在不同离河距离大都表现为聚集分布,在离河最远的地方有扩散趋势,呈随机分布;不同离河距离的两断面均表现出随离河距离加大胡杨格局规模加大、聚集强度加强的趋势,同一离河距离喀尔达依断面比英苏断面胡杨格局规模小,这主要是地下水条件和当地地形不同所致。
  • The competition among those species like s . tsinyunensis , dryopteris erythrosora and veronicastrum stenostachyum etc . , is intense in the communities , which may be one of the reasons why s . tsinyunensis is going to be endangered and with a very restricted distribution . the distribution patterns of the seven populations of s . tsinyunensis are clumped among the eight populations we studied , except population v of random distribution . the spatial pattern of 6 populations of s . tsinyunensis have high consistency with the negative binominal distribution , while another 2 populations , i . e . , i and iii are poisson distributions
    6 )缙云黄芩各种群空间分布格局基本呈聚集分布,其中7个种群的分布格局类型是聚集分布,其聚集强度较高,另有一个种群为随机分布;其种群的离散分布拟合结果也严格符合一定的数学模式,其中负二项分布、 poisson分布分别是该物种种群空间分布的理论分布模式,其中6个种群拟合出的结果是负二项分布,种群i和种群m拟合出的结果是poisson分布。
