The paper has studied the effect of formation temperature gradient, surface temperature, circulating temperature gradient, drilling fluid inlet temperature and drilling fluid type on Equivalent Static Density ( ESD ). 文中研究了地温梯度、地表温度、入口钻井液温度、循环钻井液温度梯度和钻井液类型等因素对当量静态钻井液密度(ESD)的影响;
Based on the former researches that pointed out Indian Ocean temperature distinctly influenced on the precipitation change over the region, a discriminant predictive equations were built with the former autumn, winter and spring zonal gradient of sea surface temperature anomalous. 在前人工作指出印度洋海温变化对该区降水变化有显著影响的基础上,以前期秋季、冬季和春季印度洋海温距平的纬向梯度为预报因子,建立判别预报方程。
And ③ having a geothermal gradient of 3.66 ℃ / m and surface temperature of 20 ℃. 地温梯度为3.66℃/100m,地面温度20℃。
Through analysis and measure along with data processing of Young's interfenrece fringes, temperature gradient distribution of microchannel heat sink surface natural convection temperature field and surface temperature is obtained. 对杨氏干涉条纹进行分析测量和数据处理,可以探知微沟热沉表面自然对流温度场的温度梯度分布,并可推出表面温度。
Effects of zonal gradient quasi & biennial oscillations of tropical sea surface temperature anomalies on summer rainfall over China 热带海温异常纬向梯度准两年振荡对中国夏季降水的影响
