Numerical models are frequently used to simulate water flow in hydraulic engineering. shallow water equations are basic governing equations with assumption of the velocity distribution uniformly in vertical, so they have some limitations on the simulation of some plane flows, such as wind - induced flow, curve river flow and flow nearby the submerged dikes. for above - mentioned reasons, extended shallow water equations are developed by introduction of momentum coefficient, correction of convection and bed resistance in equations of motion
在水利工程中經常需要採用數學模型模擬水流的流態，淺水方程是進行平面流態模擬計算的基本控制方程，但因其忽略了流速垂線分佈的不均勻性，在模擬某些平面流態（如風生流動、河灣水流、潛壩等工程附近的流動）時存在一定的局限性。 -
Exploiting the long jump technique parameter and treading strength in the planting step - time curve, and analyzing the kinematics and dynamics reasons for the loss of approach velocity, taking - off rapid supporting and stretching in the generating mechanism of vertical velocity during long jump take - off, the essay puts forward a new view of generating vertical velocity and offers a new thought for creating training of long jump
摘要利用世界優秀運動員的跳遠技術參數和跳遠踏跳階段踏跳力時間曲線，剖析助跑速度損失量、起跳快速支撐和蹬伸在跳遠起跳垂直速度的生成機制中的運動學和動力學原因，對跳遠垂直速度生成提出了新的見解，並為創新跳遠訓練提供了一條新的思路。 -
