The differences of the average temperature and zonal wind are compared between these two winters,with calculating EP flux and the residual mean circulation.
利用ECMWF提供的60层气象场资料诊断分析了2002/2003和2003/2004年两个冬季的爆发性增温(stratospheric sudden warming,SSW)过程,比较了两次SSW期间高纬温度和纬向风的差异,计算了SSW期间的EP通量和剩余环流。
Rational value forεin EP method;
EP法中参数ε的合理取值
In order to study the 3D static performance of EP solenoid valves in the electro-pneumatic braking system of a passenger train, the 3D FEM model and mathematical model were established according to axisymmetric structural feature.
针对EP阀轴对称的结构特点,建立有限元分析模型。
