气管

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。

Endotracheal intubation, which is the advanced methodfor securing the airway, is a demanding technique that has beenshown to be associated with infrequent success, even when usedby experienced paramedical personnel.

气管内插管是保证气道安全的进一步方法，它是一门要求高的技术，甚至当有经验的医务辅助人员操作时成功率也很低。

Hales conducts the first cardiac catheterization of a horse using brass pipes, a glass tube and the trachea of a goose.

1711年，Hales使用铜质的导管、玻璃管和鹅气管在一匹马身上首先实施了心脏介入术。

Furthermore, the geometrical ending-profile of an expansion chamber has an influence on both frequency period and amplitude of TL. The appropriate offset of inlet and outlet of an expansion muffler can increase its working frequency range. The findings presented in this paper can be used as a design guideline for a high performance muffler.

结果表明，扩张室为圆形截面的消声器性能优于椭圆形和矩形截面消声器；扩张室端部形状不仅影响消声器传递损失的大小，还影响到传递损失的变化周期；当进出气管之一与扩张室轴线偏离一定距离时，可有效地提高消声器的消声频率，改善消声性能。

The respiratory system consists of the nose, pharynx, throat, trachea, bronchial tube and lung.

呼吸系统包括鼻、咽、喉、气管、支气管和肺。

Clinically, the nose, pharynx and throat are the upper respiratory tract; and the trachea, bronchial tube and their branches in the lung are the lower respiratory tract.

临床上常将鼻、咽、喉称为上呼吸道；气管、支气管及其在肺内的各级分支称为下呼吸道。
