The column, forced to retreat, remained massed in the street, unprotected but terrible, and replied to the redoubt with a terrible discharge of musketry. 纵队被迫退却后又在街上密集,他们已没有掩护,但很可怖,他们用骇人的排枪向棱堡还击。
Practice of forced excavation discharge in reservoir emergency preparation 强制开挖放水法在水库抢险中的实践
Forced fluid discharge study and field application 强化排液研究及矿场应用
Afterwards the piping was occurred in its dam body and collapsed in the dam slope. It was decided on site to take the measure of forced discharge by excavating dam body for this emergency. The execution and the construction technique are described in this paper. 某小型水库在遭受强暴雨袭击后,坝体发生管涌,坝坡坍塌,现场决定采取坝体开挖强制放水法消除险情。
Fixing oil content of foam, the lower the input flux, the more is the pressure reduced during the forced discharge, however, pressure decreases less with high flow. 对含油量一定的泡沫,输入流量越小泡沫强制排液时的压力减少的越多,流量大压力反而减小的少。
Because of the distinct reducing of the swirl velocity and the instability of the forced vortex itself, the vortex at the volute discharge section breaks down easily, inducing the reverse flow at the center of volute discharge section. 在蜗壳出口直管段由于涡流速度明显减小和旋涡自身的不稳定,在小流量下容易发生破裂,导致蜗壳出口的截面中心区域通流速度均出现逆流,此逆流为压缩机失速特征的表现。
