We will study the properties of the distributions of OLS estimators over different random samples from the population.

通过从总体中抽取的不同的随机样本，我们将研究这些OLS估计量的分布。

Here, we report 19841883、15931603、12559817 and 16295605 mapped 35bp reads separately from the four samples, 14～18% of which were found in the exonic regions, and 19～27% of which are distributed in intronic regions.

这四个样本中分别有19841883、15931603、12559817和16295605条35bp序列被注释到小鼠的基因组上，其中14～18%的序列位于外显子区域，19～27%的序列位于内含子区域，其它序列则分布在基因间区。

To hydrological system, the samples of the hydrological factors are not sufficient, and the infection factors that formated is complex, the suppose of the probability distribution function that accord with the practical condition then undergo parameters estimation are impossible.

特别是对水文系统，各种水文要素的样本不多，且其形成的影响因素复杂，要假设出合乎实际情况的概率分布函数并进行参数估计是比较困难的。

SODT can not only handle datasets with similar or different distribution between global and local data, but also can make full use of the structure information of the labelled and unlabelled data and produce the same classification results no matter how the observations are arranged.

SODT 算法既能够处理整体数据与局部数据分布相同或不同的数据集，又可以充分利用有标签和无标签数据的结构信息，分类结果不受样本随机重排的影响，而且时间复杂度还与单变量决策树算法相同。

Because there are the characteristics of uncertainty and mixing meta-pixels in the remote-sensing images, the classical fuzzy c-means method has a low accuracy in the remote-sensing image clustering. This paper improves the fuzzy c-means method. And it adds a-priori information into the patterns to change the method as a semi-supervised clustering. In the clustering process, the unlabelled patterns compare similarities with the labeled patterns, and then the accuracy of the algorithm can be increased.(3)The paper proposes an interactive learning-based image mining in remote sensing.

由于遥感图像各类别在特征空间中散点图的分布的特点，本文对传统的FCM聚类算法进行改进，并且加入先验信息之后，将原来的非监督的聚类变成一种半监督的聚类方法，通过与已标签的样本进行相似性比较，能有效地提高聚类算法的准确度。

And in parabola-aligned images, we find that using the combination of two parabolas as the projection axis can segment teeth more precisely.

我们事先收集了一些样本，以统计的方式估计出牙齿的大小、银粉与非银粉间的颜色分布情况。

Fourth, according to the Weibull distributing functions of equivalent loads, calculated the max loads by expanded sample method, acquired eight routine loads spectrum of each roads taking advantages of the Connover classification method, calculated the respective enhancement coefficient in principle of amended Miner linear accumulated fatigue damage rule, by the comparative norm of general tar-paved road, educed the mathematical model of calculating enhancement coefficient of synthesized roads.

第四，根据各路面的等效载荷的Weibull分布函数采用扩展样本法求得了各路面的极值载荷，按照Connover的分级法得到了各路面的八级程序载荷谱。以一般沥青公路为比较基准，采用修正的Miner线性累积损伤理论，根据前桥的S-N和P-S-N关系式得到了各路面的强化系数，建立了综合路面的强化系数计算的数学模型。

In this combined sample, we find a significant correlation between the black hole mass and new-defined radio loudness.

而在加入一个由文献搜索得到的射电宁静活动星系核的样本后，我们发现在新定义的射电噪度的分布中并不明显存在R=10这个界限，同时新定义的射电噪度与黑洞质量之间却存在着强相关关系。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
