双语例句
- Linearized sample cumulative distribution frequency
线性化样本累积分布频数 - The sample distribution was accorded with Hardy Weinberg principle.

同时，基于miRNA前体在样本空间中分布，选择有代表性的miRNA前体作为训练样本。 - 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。 - 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。 - Study on the Sample Plot Distribution and Abnormal Sample Plot Probe in Monitoring Area with Principal Components Analysis
主分量分析在监测区域样地分布及异常样地探测中的研究 - By balancing the training samples, dynamically resetting initial weights and adaptively evaluating net scales, some shortcomings of the BP algorithm, such as low convergence speed and high dependency on initial sample distribution are overcome, and the algorithm has become more robust and generic.
通过平衡训练样本数量、动态重置初始权值、评定网络规模等措施，解决了BP算法收敛速度慢、受初始样本分布影响大等缺陷，提高了识别算法的稳健性和泛化能力。 - 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。 - The work of estimating the tail dependence coefficient is simple, when the sample distribution is known and the observation data is enough, the banks can use the parametric model to estimate the coefficient. But in real world, these conditions always can not satisfy.
尾部相关系数的估算较为便利，当样本分布已知且样本数据量充足时，采用参数估计尾部相关系数是非常有效的。但在信用风险管理中，这些条件有时并不具备。
