通气的

Aerenchyma is typical of the stems of many aquatic plants whose leaves float at the surface of ponds and lakes, giving added buoyancy to the tissues.

通气组织在体内形成一个相互贯通的通气系统，为植物体增加浮力和支持作用。

Once the underlying cause of respiratory failure has either improved or been resolved,and an adequate capacity of breathing spontaneously is achieved,it is reasonable in time to wean the patients from mechanical ventilation in order to avoid the dependence on mechanical ventilation and reduce the complications associated with ventilator.

但当病因消除或得到控制时，自主呼吸恢复到一定水平后，应及时撤离机械通气，避免造成呼吸机依赖和减少机械通气相关并发症的发生。

The absorption of root system was the main sources of nitrogen in the plant.The effects of matrix ventilation on the abaorption,transportion and metabolism of nitrogen in the root system of cucmber were discussed deeply.The results showed that contents of ammonium,nitrate,free amino acids and soluble protein in cucumber roots were higher in G1 treatment.Contents of ammonium,nitrate and free amino acids in cucumber roots were the trend of the dropping after the first rising in F1 treatment,but contents of soluble protein was lower11.03%than that of the control.

根系吸收是植物体内氮素的主要来源，本研究深入探讨了基质通气状况对黄瓜根系氮素吸收、运输和氮代谢的影响，结果表明G1通气处理根系的铵盐、硝酸盐、游离氨基酸和可溶性蛋白含量均较高；非通气处理(F1处理)根系内铵盐、硝酸盐和游离氨基酸含量呈先升高后降低的趋势，而可溶性蛋白含量始终较低，比对照降低11.03%。G1处理根系硝酸还原酶、亚硝酸还原酶、谷草转氨酶、谷丙转氨酶、谷氨酰胺合成酶活性均较高；而F1处理的酶活性在处理末期显著降低，其中谷氨酰胺合成酶活性比对照降低33.33%。

The solid flow rate of aeration downflow was slightly less than that of aeration horizontal.

由整体方面来看，通气方向向下时的固体输出量虽略小於水平方向通气，但比较标准偏差可知通气方向向下时，下降管的压力扰动相当小，即可得到较稳定的操作。

The solid flow rate of downflow of inlet gas was slightly less than that of horizontal flow of inlet gas. But the standard deviation of pressure signals of downflow of inlet gas decreased significantly, causing more stable operation.

由不同通气方向来看，通气方向向下时的固体流量虽略小於水平方向通气，但可使下降管中的压力扰动明显减少，即可得到较稳定的操作。

Use intermittent positive pressure ventilation mode in ALI dogs, calculate Elastance and Resistance, then change to PAV, set the assist ratio 80％、60％、40％、20％randomly, Observe the changes of respiratory mechanics、blood gas analysis and hemodynamics during mechanical ventilation.

对10条ALI犬先用间歇正压通气模式通气，同时弹性阻力和粘性阻力，然后将模式改为PAV，随机设置辅助比例80％、60％、40％、20％，观察通气期间呼吸力学、血气和血流动力学的变化。

The results of respiratory mechanics, homodynamic mechanics,aterial blood gaS, and inflaInInatory factors [TNF- Q, IL-l fl, IL-6,IL-l0, and adrenomedulin] which detected in animal serumand bronchial alveolar lavage fluid obtained from tiP lObe,heart lobe, and diaPhragIn lobe of right lung seParate1y in the mongreldogs were measured before and after lung injury (including receivinglung protective ventilation).

本实验证明了 loS肺内／肺外不同源性 ARDS动物模型的差异性，而且AnDS的肺部病变存在不均一性和多形性的特点，对有关ARDS进行性低氧血症的发生机制提出了肺动静脉可能存在类似于右一左分流的肺内分流现象，以及因肺内分流而导致严重通气／血流比例失调的解释。发现小潮气十PEEP通气对肺内源性 ARDS疗效不佳，而俯卧位＋小潮气－I－ PEEP通气对肺内／肺外不同源性ARDS均有较好的疗效。。

When initial NO3--N was leached, the correlation coefficients between soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation with raygrass nitrogen uptake were decreased to 0.613 and 0.607, respectively, and both reached 5% significantly level. However, the correlation coefficients between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogen uptake were raised obviously, and all reached 5% and 1% significant level.

以不包括土壤起始NO3--N盆栽试验植物吸氮量为参比，通气培养前CaCl2淋洗起始NO3--N和起始矿质氮与五期黑麦草地上部氮素累积量间的相关性尽管有所降低，但相关性仍达5%显著水平，相关系数分别为0.613和0.607；而通气培养30周矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、N0及N0+起始矿质氮与五期黑麦草地上部吸氮量的相关系数却明显提高，相关系数分别为0.718，0.782，0.688 和0.640，均达5%或1%显著水平。

Three hours OLV does not cause injury of the nondependent lung, yet six hours OLV leads to injury of the nondependent lung. Low-dose ALM would not deteriorate the injury of the nondependent lung.

OLV 3hr不会造成无通气肺组织的损伤，而OLV 6hr则引起无通气肺组织的损伤：小剂量ALM在提高HPV反应，改善OLV期间动脉氧合的同时，并不加重无通气肺组织的损伤。

The FiO2, PaO2, PaCO2 and OI, before and after treatment of HFOV or CMV, were observed, and clinical effects, ventilation time, hospital stay and cost spent were compared. Results The patients' condition in HFOV group significantly improved within 24 hours, and airleak disappeared in short time without thoracentesis or closed drainage.

重症气漏并呼吸衰竭新生儿38例， 15例常频通气治疗， 23例高频震荡通气治疗，观察HFO组治疗前后吸入氧浓度(FiO2)、动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)及氧合指数的变化及临床疗效，并与CMV组机械通气时间、住院天数及医疗费用进行比较。

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。
