density variation meaning in Chinese
密度变化
密度偏差
Examples
- Environmental-temperature variations contribute to uneven air pressures due to density variations of the air in the bellows .
环境温度的变化将引起波纹管内空气密度的变化，造成气体压力不稳定。 - Radiograms and bone density variation of the cervical spondylosis patients at differ stage
不同时期颈椎病患者颈椎骨密度变化与椎体变形关系 - Abstract : non - spot pollution source was analyzed qualitively and quantitatively on the basis of experiment data of pollution density variation during raining and flood process . the experiment result is in agreement with the observed reality . a calculation method for non - spot pollution source was presented
文摘:利用雨洪过程中污染物浓度变化的试验资料，对非点源污染进行了定量和定性分析，指出非点源在雨洪过程中的作用特点与试验成果有很好的一致性，提出了一种粗略测算次雨洪非点源量值的方法。 - Based on the discussion on the principle of density - logging , this paper analyses far - gamma gamma rate , near - gamma gamma rate and density - logging curve respectively , and discusses far - gamma gamma rate near - gamma gamma rate and density variation caused by radioactive anomalies , and preliminarily interprets factors that could lead to the variation of density - logging curve of radioactive anomalous layer , thus explaining the reason why density - logging curve changes at the radioactive ore - layer in northern ordos basin , finally , an empirical formula for revising the distortion of density - logging curve has been established
摘要本文概述了密度测井原理，分别对长源距计数率、短源距计数率及密度曲线进行分析，对由于放射性异常引起的长源距计数率、短源距计数率及密度变化情况进行了讨论，初步解释了放射性异常层位密度曲线的变化因素，说明了鄂尔多斯盆地北部地区密度测井曲线在放射性矿段的变化原因。
