To check, a sample measurement on the full size gun shows it to be 8.5 from the tip of the barrel to the back of the rear sight.

检查，抽样测量对充分大小枪显示，它是8.5 从尖端桶，以后面的后方视线。

To overcome the drawback that the traditional Linear Grouping Algorithm, when extracting linear structures, is sensitive to outliers in datasets, a new finite step according to existence of optimal linear grouping in data set and a new algorithm based on k-means clustering, total least absolute deviation and resampling were proposed, which detected several different linear relations at once to minimize the total orthogonal distances from n given points to its nearest hyperplanes.

为克服传统提取数据集中线性结构的LGA对噪声数据比较敏感的缺陷，提出了两种基于稳健的全最小一乘准则下的LGA新算法。首先证明了全最小一乘准则下数据集最优划分的存在性，并据此给出一种有限步终止算法。其次为提高计算速度，根据k-means算法、全最小一乘准则和重抽样方法给出另一种快速收敛算法。

Abstract］ Objective To investigate whether there is difference of blood pressure between left and right arms in order to provide the reference materials for clinical blood pressure measurement.Methods Two hundred university students were recruited in this study by randomly sampling in different layers.Using both mercury manometer and electronic manometer at the same time,the blood pressure of both arms was measured when the student was sitting by the researcher with standard measuring methods.

目的 调查学生双上肢肱动脉血压有无差异，临床血压测量提供参考资料方法采用分层随机抽样法抽得在校大学生共200人，按标准方法固定专人分别用汞柱台式血压计和臂式电子血压计测量坐位的双上肢血压。

The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy.

探测器阵列(1)的间距小于入射强度辐射图的节距、使得后者被过抽样，由此得到高精度。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
