预测了壁面压强和轴心速度分布,并与实验数据进行比较,计算值与试验值吻合很好。
Predictions have been made and compared with experimental data pertaining to the centerline velocity decay and wall static-state pressure variation.
高速水流中的水流脉动对水工建筑物的安全运行存在很大的影响,水流脉动压强的特征值一般需通过水工模型试验确定。
The pulsate pressure in high speed flow water will influence the safety of water construction, and the eigenvalue of the pulsate pressure should be confirmed by hydraulic model testing.
根据统计分析和贝叶斯估计结果,建议了强度等级为C20和C30再生混凝土抗压强度的标准值与标准差的取值。
Based on the results of Bayes estimations, the standard deviations for the compressive strength of RAC with strength grades of C20 and C30 were proposed.
OK, we're going to do this reversibly, which means we're going to slowly change the external pressure very, very slightly at a time, so that at every point we're basically in equilibrium, p2/ until the pressure reaches a new smaller pressure p2.
整个过程保持可逆,外界压强,变化得很慢,每一个瞬间,都保持平衡,直到压强减小到末态值。
If I look at different points in my container during that path, I'm going to have to use a different value of pressure or different value of temperature That's not an equilibrium state, and that process turns out then to be an irreversible process.
如果我要研究在路径中容器里的,不同的点,我就得在容器里不同的点上使用,不同的压强值,或不同的温度值,实际上这不是个平衡态,这个过程是,不可逆过程。
