气管的

Since the manufacturer's product could be used with two sizes of flue pipe, the experiment involved varying the air intake setting (1/4, 1/2, 3/4, and full open) and the flue size, and measuring the temperature and the relative level of particulate matter exiting the stack.

既然生产商的产品可用于两种规格大小的暖气管道，那么这个实验就包括调整进气管的设置（1/4，1/2，3/4或完全开放）、调整暖气管道的尺寸，并且测量温度和相关微小物质的含量。

Successful tracheal intubation wasverified using the following criteria: 1 identification ofthe trachea and tracheal rings, 2 visualization of vocal cords,3 widening of glottis as the tracheal tube passes through,and 4 tracheal tube position above carina and demonstrationof movement of the chest wall visceroparietal pleural interface(i.e., sliding sign) after manual ventilation of the lungs.

成功的气管插管通过如下的标准证实：1）辨别气管和气管环，2）可见到声带，3）当气管导管置入时声门变宽，4）隆突上气管导管的位置以及手控通气时胸壁内脏壁胸膜界面的运动。

The other is the first step on the path to a particular sort of tissue such as the lining of a windpipe.

其他的则分裂成形成特定种类组织的初始阶段的细胞，例如气管的里层

In our case, the CT images showed the mass is positioned in the right side of the trachea, and the superior side of right superior lobar bronchus.

从我们的病历影像可以知道肿瘤的位置是在气管的右侧，右上肺叶支气管的上方。

Collings found that all tastes can be detected anywhere there are taste receptors—around the tongue, on the soft palate at back roof of the mouth, and even in the epiglottis, the flap that blocks food from the windpipe.

库林斯发现舌头周围任何有味觉受体的部分都能品尝出所有味道，比如口腔上层后半部分的软上腭，甚至会厌软骨和防止食物进入气管的口盖都能品尝出所有味道。

Gliding over filter-feeding strawberry ascidians and stinging hydroids, a greenspot nudibranch senses the sea with hornlike organs called rhinophores.

西太平洋，1996一只绿斑点的海兔滑过用滤器捕食的粉红色海鞘和带刺的水螅，伸出叫做通气管的角状器官来感知大海。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

A swimmer with a snorkel can still breathe, but notice that snorkelers float right on the top. Were they to try sinking underneath, even a moderate amount, the same thing would happen.

带了一个通气管的游泳者仍然能够呼吸，但是有一点要注意的是，这是游泳者刚好漂浮在水面上，如果他们尝试这潜的深一点的话，即便是慢慢的潜入，呼吸还是很困难。

In this paper, a specially made root chamber system with two compartments and nine gas collection pipes was used to collect the N2O in soil air of nine different spatial position in the root chamber. The following treatments were also used:(1) Two selective nitrification inhibitors, C2H2 and DCD in low concentration were used to study the nitrification process under different NH4+-N levels and its contribution to N2O release.

用特制的带有9根采气管的两室根箱系统，采集和分析根箱中9个不同部位土壤空气中N2O的浓度，结合使用具有选择性的硝化抑制剂（包括低浓度的C2H2和DCD），研究在不同铵态氮水平下的硝化过程及其对N2O气体释放的贡献；结合使用高浓度的C2H2，抑制反硝化过程中N2O到N2的还原，研究在不同铵态氮水平下的反硝化过程及其对N2O气体释放的贡献。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
