useful flux的意思|示意

The vorticity flux divergence of the high frequency eddies in the maintenance of the blocking is also discussed. Some useful results are thus acquired.

通过分析和讨论阻塞形成、维持和衰亡过程中低频涡动和高频涡动的矢量型以及高频涡动对阻塞流型的强迫作用，得到了若干有意义的结果。

Decreasing the heat flux or outlet two-phase resistance, and increasing the system pressure or inlet single-phase resistance are useful to avoid the natural circulation flow instability.

增大系统压力、减小热流密度、增加入口单相阻力、减小出口两相阻力有利于避免自然循环流量漂移的发生。
