查询词典 reverse flow

On the other hand, flow cytometry was employed to detect the action of paclitaxel to cell cycle and apoptosis. Reverse transcription polymerase chain reaction is employed to detect the influence of paclitaxel on Survivin mRNA expression. The purpose of the study is to provide theoretical basis to carcinogenesis, progress, metastasis, angiogenesis and clinical chemotherapy of paclitaxel on TSCC.

动物于头高脚低位至瓣膜开始关闭时，实验组均出现血液返流现象，返流流速（1.4 ± 0.3）cm/s；对照组未出现血液返流现象，但血液流速下降，由高峰流速（21.3 ± 2.1）cm/s 减至（18.2 ± 3.3）cm/s。

Operational Versatility- Patented self-centering seat ring and rugged plug allow forward or reverse flow with tight shutoff in either flow direction.

业务多功能专利的自定心座圈和坚固的插件允许正向或反向流动，在两个流动方向紧关断。

Operational Versatility- Self-centering seat ring and rugged V-notch ball allow forward or reverse flow with tight shutoff in either flow direction.

Color Doppler flow imaging showed the reverse flow of ductus arteriosus in 5 cases and tricuspid regurgitation in 3 cases.

目前国内已有超声诊断肺动脉闭锁的报道[1-3]，但鲜见产前超声诊断胎儿肺动脉闭锁的报道。

The discrete frequency component of velocity fluctuation at the off-design operating conditions is generated in vortical flow region as well as in reverse flow region.

离散频率包括在非设计操作情况下产生的波动速度的频率，同旋转气流区域和反向气流区域相似。

Numerical simulations showed the axial velocity in the precessing flow were decreased significantly because of the entrainment of ambient air. The swirling motion, the wall attachment effect and the reverse flow were also found in the numerical flow field. It is shown that the simulation results of the precessing jet flow accord well with the analysis and the previous work.

数值模拟表明旋进射流的轴向流动速度衰减得很快，流场中存在明显的旋流、附壁效应和反向回流现象，所得到的结果与已有的分析结论基本吻合。

Cut off cut-off valve is mainly used for fluid pathway, including the cut-off valves, gate valves, plug valves, ball valves, butterfly valves, diaphragm valves, control API Cast Steel Valves valves and other folders; The main control valve for regulating fluid pressure, flow, etc., including control valve, throttle, valve and float valve, etc.; Check valve used to prevent reverse flow of fluid; Shunt valve fluid channel for distribution of destination, or two-phase separated, including slide valves, multi-valve, trap, and emptying valves and so on; Safety valve is mainly used for security, to prevent the boiler, pressure vessel or pipeline overpressure due to the damage; Multi-valve is a valve with more than one function, such as the cut-off valve can both start and end back from the role of the role of drying.

截断阀主要用于截断流体通路，包括眼镜阀截止阀、闸阀、旋塞阀、球阀、蝶阀、隔膜阀、夹管阀等；调节阀主要用于调节流体的压力、流量等，包括调节阀、节流阀、减压阀和浮球调节阀等；止回阀用于阻止流体的逆向流动；分流阀用于分配流体的通路去向，或将氧气专用阀、铜阀门两相流体分离，包括滑阀、多通阀、疏水阀和排空气阀等；安全阀主要用于安全保护，防止锅炉、压力容器或管道因超压而破坏；多用阀是具有一种以上功能的阀门，如截止止回阀既能起断流作用又能起止回作用。
