PVC：压力-速度修正

“Pressure Velocity Correction”在学术和科研领域，特别是化学及相关学科中，常被缩写为PVC，以方便书写和日常使用。该术语的中文译名为“压力-速度修正”，用于表示压力与速度之间的校正关系。通过使用缩写，研究人员能够更高效地进行记录和交流。

Surface scanning with 3 D block correction technique as well as prediction and correction method in the pressure and velocity correction were used to promote the convergency, the rate and accuracy of convergence.
采用面扫描结合三维块修正的技术，并在压力和速度修正方程中运用了预测和校正技术，使得程序的收敛性、收敛速度和计算精度大为提高。
The grid generation technique, difference scheme of convective and diffusive terms, pressure and velocity correction methods and arithmetic of nonlinear equations are determined.
确定了本文数值模拟所采用的网格的生成技术，对流扩散项的离散格式，压力修正与速度修正方法，以及非线性代数方程组的求解方法。
The pressure field and velocity field are correlated by a pressure correction equation.
应用压力加权校正算法，实现了速度场和压力场的关联。
The predicted pressure is obviously lower than the actual pressure. VSP logging velocity is more sensitive to the overpressure section as compared to seismic horizon velocity. Use of VSP velocity for correction of the seismic velocity can substantially reduce the systematic errors.
VSP测井速度较地震层速度对超压段更为敏感，利用VSP速度对地震速度进行校正，可以大大降低这种系统误差。
