例句与用法
- Finally , the correlation between partial silt indexes is studied . the correlation analyses between physical indexes can be used to decide whether these indexes can be looked as independent variable at the same time in reliability design , furthermore , the correlation between mechanical and physical are also studied and some empirical equations with practical usage are drawn up
本文对物理指标间的相关性作了研究，这在可靠性设计时，它们能否同时作为独立随机变量处理具有重要的意义；同时，又对压缩指标、强度指标与物理指标间以及不同类强度指标间的相关关系作了分析，得出了一些有实用意义的经验公式。 - Secondly , by characteristic statistic , the probabilistic distribution of silt indexes is roughly learned , then the normal and beta distribution probabilistic models are fitted for generally symmetric distribution indexes , and the beta distribution models for all indexes owing to their good adaptability . after tested , the indexes of cuu and < t > m fitted by the beta models are very good
其次，用特征统计量对粉土工程性质指标的概率分布作了粗略了解后，对大致对称分布的指标作了正态分布和beta分布拟合，对不对称分布的指标作了beta分布拟合，最后得出用beta分布拟合c _ ( uu )和_ ( uu )是较理想的。 - Based on the engineering geologic investigation reports of 22 buildings and the author ' s own tests in lab ( which includes 18 groups of conventional test and compression test , 8 groups of unconsolidated undrained triaxial test and 8 groups of quick direct shearing test ) , taiyuan silt is studied in the paper . firstly , the variability of silt indexes is analyzed . the analyses results show the change laws on variability , in addition , the average value and variability coefficient ranges of silt indexes are given for reference
本文以太原地区粉土为研究对象，在收集、整理了22个建筑工程场地勘察报告和作者室内试验成果( 18组常规试验和压缩试验、 8组不固结不排水三轴剪切和8组直剪快剪试验)的基础上，对太原粉土作了以下方面的分析研究：首先研究了粉土工程性质指标的变异性，得出了变异系数的变化规律，给出了各工程性质指标均值和变异系数范围的建议值。
