Secondary vent stack , assistant vent stack

仅与环形通气管连接，为使排水横支管内空气流通而设置的通气立管。

Therefore two-chamber single-thrust rocket motor structure was put forward.

使用增加发动机药量的方法，提高一室一推的火箭发动机推力时，通气参量过大直接影响发动机的燃烧性能。

Thrust tests show that two-chamber single-thrust rocket motor structure can effectively reduce the port parameter of the combuting motor,at the same time,make the motor combust stability.

推力试验表明：两室一推发动机结构能有效地减小燃烧时的通气参量，同时使得发动机燃烧稳定，可以用小火箭模拟大火箭的加速度曲线。

Respiratory manholes, Fire breathing manhole is installed in the tank on top of the security emergency ventilation devices, usually supporting the use of Fire breathing valve, since the cause of the accident causing the tank to avoid a sharp pressure or vacuum, the damage to storage tanks and accident, fire can play a security role, is to protect the tank$$#$$s safety device, especially for storage of material to cap the dome pressure nitrogen tank.

呼吸人孔、阻火呼吸人孔是安装在储罐顶上的安全应急通气装置，通常与阻火呼吸阀配套使用，既然避免因意外原因造成罐内急剧超压或真空时，损坏储罐而发生事故，又能起到安全防火作用，是保护储罐的安全装置，特别适用于贮存物料以氮气封顶的拱顶常压罐。

Were randomly divided into two groups:68 cases with conventional insertion of gastric tube,78 cases with setting the leaving alone stomach tube vertically.

目的：提高机械通气患者留置胃管的一次性插管的成功率，减少插管过程的不良反应。

The present study is designed to investigate the usefulness of a new diagnostic criteria of MEFVC, flow volume angle, for the diagnosis of ventilatory dysfunction and early detection of small airway obstruction. Meanwhile, we also establish the predicted normal value of the pulmonary function testing and to investigate the possibility to predict body height by measurring the length of arm span or sitting height.

本研究之目的是利用流量容积角当作用力呼气流量容积图形之新的诊断指标，轨整体通气功能与早期呼吸道阻塞方面之诊断能力进行探讨，同时建立正常人之肺功能预测值公式，并讨论量取手臂长或坐高对推测预测值公式中之身高这项变数的可行性。

The results show that (1) the flow volume angle A50 is a reliable parameter for the diagnosis of MEFVC;(2) the flow volume angle A75 has the best sensitivity for early detection of small airway dysfunction;(3) we also establish the normal predicted equations of pulmonary function testing for the adult Chinese in Taiwan area.(4) length of arm span and sitting height are reliable indices to predict body height for the calculation of normal pulmonary function data.

结 果显示：流量容积角A50 可当作用力呼气流量容积图形之总体肺通气功能检查的诊断指标；流量容积角A75 对早期小呼吸道之功能不彰具有侦测的功能；本研究亦建立了在台湾地区之成年中国人的正常肺功能预测值公式，以供参考用；量取手臂侵与生高之值确可用来推测身高值。

The ventilated MAM nipple is thin, soft, silky-smooth and provides the baby with a comfortable skin-soft feeling.

有通气功能的MAM奶嘴薄，软，丝质光滑，让宝宝喝的舒服

The Spirulina yield can be enhanced effectively by the increase of illuminated area, aeration rate and temperature. A higher efficiency of light utilization was observed in 500ml mini PBR than in 64 l large PBR.

增加光照面积、提高通气速率和培养温度能够有效提高螺旋藻的产量。500ml小型光反应器比64 l大型光反应器具有更高的光效。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
