effective ventilation meaning in Chinese
有效通气量
Examples
- The experimental studies of heliox decreasing air way resistance and improving pulmonary effective ventilation
氧混合气降低气道阻力和提高肺有效通气的实验研究 - The basic requirements include good cyclonic inflow i . e . for the northern hemisphere , inward spiralling in an anti - clockwise sense at the lower levels for the initial spin - up process , and good outflow channels at the upper levels for effective ventilation . the convergence of air at the lower levels and divergence aloft imply a vertical circulation which is schematically shown in the following cross - sectional diagram
热带气旋的诞生及发展的基本条件是：在大气低层必须有充份的气旋式气流辐合（在北半球，沿反时针方向螺旋形地流入） ，在大气高层要提供足够的气流外溢通道，这样才可以建立有效的通风机制。 - Because there are small openings and the three cracksin the concrete lining of gas tunnel , the gas should intrude into the gas tunnel built . this effect will endanger the transport safety . the authors study on the operation ventilation technology in the gas tunnel and put forward an economical , safety and effective ventilation plan , and therefore furnish a theoretical basis for the gas tunnel ventilation design in the future
由于瓦斯隧道混凝土衬砌本体中的细小孔隙和“三缝”等缺陷的存在，建成后的瓦斯隧道必然受瓦斯侵袭，这对运营安全危害极大，为此，本文对瓦斯隧道运营通风技术进行了认真研究，提出了经济、安全、有效的通风方案，为未来瓦斯隧道的通风设计提供了理论依据。 - Otherwise , further development and intensification will be inhibited . the basic requirements include good cyclonic inflow i . e . for the northern hemisphere , inward spiralling in an anti - clockwise sense at the lower levels for the initial spin - up process , and good outflow channels at the upper levels for effective ventilation
