This paper analyses the application of the optimal variable relaxation method in threedimensional model with ten different properties, based on explicit points constant successive over relaxation and implicit blocks constant line relaxation. 文章以点显式定常逐次超松弛法和块隐式定常线松弛法为基础,分析了10种不同特性的三维油藏模式中变时空最佳点松弛法的适应性。
A homogenization-based method for predicting the visco-elastic property of undirectionally jointed rock is presented, and the explicit formulae for predicting the visco-elastic relaxation modulus are obtained. 基于均匀化理论,建立了单向节理岩石粘弹性性能的预测方法,给出了解析形式的粘弹性松弛模量预测表达式。
Physicians played a more important role in mode of delivery decision-making process in cesarean section with explicit indications and ambiguous indications. However, tense doctor-patient relationship was an important factor for relaxation of cesarean section indications. 产科医生在孕妇决策不明确指征剖宫产和明确指征剖宫产中发挥较为重要的作用;但紧张的医患关系是医生放宽剖宫产指征的重要原因。
