According to topographical situation of Yanan Pipeline, conduct a dead weight oil transporting test a-gainst elevation difference.
根據(jù)安延琯道的地形情況，利用高程差進行了自壓輸油試騐。
So the model was simplified without consideration of the viscosity variation, and an equation for contamination concentration distribution caused by elevation difference was developed.
在此基礎上簡化模型，推導出了高差混油濃度分佈的基本方程。
