双语例句
- Interval Estimates and Hypothetical Test Metod of Parameter On Few Sample Uniform Distribution
小样本的均匀分布参数的区间估计和假设检验 - On the basis of image segmentation, pixels in bubble segmentation region were calibrated. At the meantime, concept of sample distribution statistics was introduced. Moreover, some statistical characteristics, such as the average size of bubbles, variance, skewness and abruptness were extracted.
在图像分割的基础上，对气泡分割区域像素进行标定，引入样本统计分布的概念，提取了气泡平均尺寸、方差、偏斜度及陡峭度等统计特征。 - Flow fields and the sample particle distribution were calculated under different circumstances.
计算了不同情况下的流场分布和样本粒子分布。 - In all, the researches are small sample and distribution of a single region. It is lack of the comprehensive study with large scale and multi-centre.
总体上各项研究均为小样本、单一地区的散发研究，缺少多中心大样本的综合研究。 - The over-convergence and uniformity validations are introduced to verify correspondence between sample distribution and sensor information for timely resampling which highly saves computational resource and enhances localization efficiency.
同时在重采样过程中引入了过收敛检验与均匀性检验用于判断采样与感知信息的匹配程度，以适时进行重采样，节省了计算资源并提高了定位效率。 - Study on the Sample Plot Distribution and Abnormal Sample Plot Probe in Monitoring Area with Principal Components Analysis
