They include the variation of the degradement velocity of different sample, the inhibition product of PCR, the amount of DNA extraction, quality of DNA and the heteroplasmy of some tissue. Correct sequencing, comparison of the result of forward and reverse primers sequencing should be done to rule out wrong signals, and prevent contamination. In addition to gene sequencing, low grade heteroplasmy could be dealt by Denaturing high performance liquid chromatography. Multiplex Ligation-dependent Probe Amplification. The analysis of mitochondrial HV Ⅰ, HV Ⅱ sequencing is able to identify the maternal sanguinity, then it could assist in the human identification. It also complements the genomic STR system in distribution of population, the origin of human, and analysis for fossil.

In so doing, we expected to obtain the information regarding particle size and size distribution of AuNPs directly from the electrophoresis results. In this experiment we used 10mM Sodium tetraborate and 10mM Sodium phosphate containing 200mM Sodium dodecyl sulfate as electrophoretic run buffers (pH 8.8), and AuNP Standards were treated with the synthesized compound hexyl-oligo(p-phenyleneethyny-lene)-poly as the sample and separated by CE.

根据电泳最佳条件的实验结果，我们采用10mM Sodium tetraborate与10mM Sodium phosphate并添加200mM Sodium dodecyl sulfate作为缓冲溶液（pH 8.8），以经实验室合成的界面活性剂（hexyl-oligo (p-phenyleneethyny-lene)-poly，Hex-OPE-PEO）修饰过后的金奈米粒子标准品作为样品进行电泳实验，将所测得的电泳迁移率与标准品颗粒大小做一校正曲线，可以得到最佳的电泳迁移率－粒径大小之线性关系（R2＞0.99）。

Based on velocity and direction distribution of mobility model, this text put forward the scheme of simulating the movement of mobile station and the methods of computing the sojourn time, then make statistical analysis on the sample to obtain the probability density function of the sojourn time and the probability of handover.

在移动模型运动速度和方向分布的基础上，利用Matlab模拟移动模型在小区内运动轨迹，并随时判断移动模型是否离开小区，以此计算移动模型在小区内的停留时间，并对多次计算所得到的大量数据进行统计，得出停留时间的概率分布，并推倒切换发生率。

In order to manifest how the main bodies react to each other during the spinoff process of new ventures; we theoretically summarize and analyze the modes of resources distribution on the basis of sample investigation and typical case study.

6在实证调查的基础上，给出了当前我国衍生高技术企业主要创业者创业动机的详细描述，反映了我国高技术企业创业者创业动力的实际情况。

Therefore, research on non-statistical evaluation of measurement uncertainty with small sample size and unknown statistical distribution has important theoretical significance and practical value.

因此，研究小样本量、未知分布下的测量不确定度的非统计评定理论具有重要的理论意义和实际价值。

Firstly, the distance between stocks are calculated by using prices of stocks, and subdominant ultra-metric space by associating the minimum spanning tree of portfolio. Secondly, the subdominant ultra-metric space to the chart of index hierarchical structure is transformed, and finally the distribution of style is gained. Using sample of Shanghai Stock 50 Index from 2004 to 2007, the demonstration result shows that style of industry is more prominent horizontally, especially in the bank and steel industries. The style of region and cross holding also exists. And after the reform of non-tradable shares, style of industry becomes more obvious vertically and more other styles also occur.

首先利用股票价格计算出股间距离，并采用关联该证券组合的最小生成树优化方法，从而得到亚超度量空间；其次将此亚超度量空间转换成指数分层结构树图，最后得到风格的分布特征。2004~2007年的上证50实证结果表明：横向来看以行业分类的风格较为显著，其中以银行和钢铁也最为明显，此外还有与地区差异、交叉持股相关的风格效应显现；纵向则在股改后行业风格效应更显著，其它的风格也显现得更多。

If we wish to avoid the inaccuracies caused by the size of the sample , we need to use the T distribution.

为了避免因样本容量大小而造成的误差，我们必须使用T分布。

Based on physical characteristics, existing stochastic estimation methods of equipment sensitivity to voltage sag use subjective probability models to express the probability distribution of voltage tolerance curve of equipment in the uncertain region. But the parameter estimation needs vast sample data. These methods may result in man-made errors.

现有负荷敏感度随机估计法以电压暂降的物理特征为基础，用主观概率模型描述负荷电压耐受曲线(voltage tolerance curve，VTC)的随机分布规律，所需样本量大，在实际中难以实现且可能引入主观误差。
