气管内的

Voltage type, it uses a closed rotor, can be widely used in smoke delivery type, delivery type air pressure and vacuum conveying system conveying equipment, it can guarantee the flow pipeline pressure, not leaking, safe delivery and collection node materials, and for this reason called the million air lock, and it can not only pressure, while both common features.

耐压型，它采用封闭型转子，可以广泛用在吸送式，压送式气流输送系统和负压输送设备上，它可以保证输送管内的气流压力，不泄漏，能够安全的输送和收结物料，所以在这方面称为万锁气器，它不但可以耐压，同时兼备普通型功能。

With a gradual contraction longitudinal straight inlet port applied on the Multi-Point Injection natural gas engine, the concentration of natural gas and the pressure field in the intake manifold after the injection of natural gas were investigated, then in the following intake process the volocity vector map and mass distribution of natural gas inside the cylinder were also numerically examined.

在此基础上，考察了渐缩形直进气道应用於多点电喷天然气发动时，天然气喷射后进气岐管内的天然气浓度场和压力场，以及随后天然气-空气混合气在气缸内的质理分布和速度分布。

The flow pattern in the standpipe is moving bed flow in experiment.

在实验范围内，立管内的流动形式主要为气固并流下行移动床流动。

Results show that with the increase of the apparent gas velocity in the riser,there is little change in negative pressure gradient in the standpipe.

结果表明：随着提升管内表观气速的增加，立管内的负压差梯度变化不大；而随着系统循环量的增加，立管内的负压差梯度以及滑移速度均增大；随着加入热解室内松动气量的增加，立管内尤其是立管上部的压力也随之增大，热解室内无论是移动床流动还是流态化流动均对立管的稳定性影响不大；但当热解室内的压力超过某一值时，立管内的料封很快被破坏，导致系统无法运行。

It can occur within the lung parenchyma or in an endobronchial location.

在肺部，传统的错构瘤表现为含有软骨和脂肪组织的边界光整的肿块，可发生在肺部实质，也可发生在支气管内。

Choking is a serious problem in pharyngoesophageal reconstruction.

随著这条支线，那些食物会跳过那些会厌周遭损坏的地区和气管，避免在吞咽的时候哽咽或者是吸入食物到气管内。

First, calculating the pressure pulsation in the condition of different velocity and pulsant frequency through using CFD software, then calculate the ahead natural frequency and length of resonance, which offer a reference to the select of pipe length in Hot Blast Stove.

利用通用CFD软件计算不同速度、脉动频率下压力不均匀度沿管道的分布情况，同时计算出管内气柱的前几阶固有频率及共振管长，该方法为热风炉管道系统选取合适的长度提供了参考。

It is found by the numerical calculation of single phase flow and the experimental results of two-phase flow that the fairing rings in the inlet and outlet of the vertical parts of inverse U tube can increase the flow stability of gas-liquid flow.

通过对单相流体在倒U型管内的流动进行数值计算，结合两相流体流动的实验结果，发现在倒U型管垂直段两端内置整流环可以增强倒U型管内气液流动稳定性。

To get the pressure drop for the design of air-lift in the borehole hydraulic jet mining, the model of three-phase flow was developed.

为得到在钻孔水力开采关键设备中气举设计所需要的压降参数，建立了气举提升管内的气－液－固三相流压降数学模型。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
