Respire To breathe in and out inhale and exhale .

呼吸：吸气和呼气；吸入和呼出转贴于

Methods The concentration of exhaled NO was measured by chemiluminescence method in 128 normal children (7～12 years of age) and 76 asthmatic children( 6～14 years of age). The FEV1% of asthmatic children was measured by a pocket spirometer at the same time.

采用化学发光法对128名7～12岁正常儿童和76例6～14岁哮喘患儿进行呼出气NO浓度测定，同时测定哮喘儿童一秒钟用力呼气容积(FEV1)及其占预计值百分比(FEV1%)。

Spirometry involves measuring how much air you can exhale after first taking a deep breath, and how quickly you can empty your lungs.

肺活量检查所要测定的值包括你在深吸气情况下的最大呼气量以及你的最大呼气速度。

Some filtering facepiece respirators have an exhalation valve which can reduce breathing resistance, reduce moisture buildup inside the respirator and increase work tolerance and comfort for respirator users.

有些随弃式呼吸防护口罩还带有呼气阀，呼气时可以降低阻力，减少面罩内湿热空气的积聚，提高工作中呼吸器使用人员的耐受性和舒适性。

Resujts:① The distribution of lesions are mostly symmetrical, extensive, predominant in the middle and lower lung fields, and posterior areas in peripheral;② There are so many HRCT findings of lung, ILD is predominant: intralobular interstitial thickening 46 cases (100%), ground-glass opacity 41 cases (89.13%), peribronchovascular or centrilobular interstitial thickening 40 cases (86.96%), interlobular septal thickening 38 cases (82.61%), irregular linear opacity 37 cases (80.43%), small nodular opacity 34 cases (73.91%), subpleural line 27 cases (58.70%), bmnchiectasis or bronchiolectasis 19 cases (41.30%), patch opacity 18 cases (39.13%), expiratory mosaic sign 15 cases (32.61%), interface sign 14 cases (30.43%), honeycombing 12 cases (26.09%), emphysema or bulla 3 cases, cystic airspace suspected 1 case, and atelectasis suspected 1 case;③ Mediastinum and pleura: multiple small lymphonodi in mediastinum 41 cases (89.13%), pleural thickening or rough 38 cases (82.61%), esophagoectasis 11 cases (23.91%), unilateral little pleural fluid 1 case, and mediastinal emphysema 1 case.

结果：①皮肌炎肺部病变分布呈对称、广泛、偏中下、偏外后的特点；②肺部HRCT表现多样，以肺间质性改变为主：小叶内间质增厚46例(100%)，磨玻璃影41例(89.13%)，支气管血管束增宽或小叶核心增大40例(86.96%)，小叶间隔增厚38例(82.61%)，不规则纤维索条影37例(80.43%)，结节影34例(73.91%)，胸膜下线27例(58.70%)，支气管或细支气管扩张19例(41.30%)，斑片影18例(39.13%)，呼气相马赛克征15例(32.61%)，界面征14例(30.43%)，蜂窝影12例(26.09%)，肺气肿或肺大泡3例，单纯囊状气腔1例，肺不张l例；③纵隔及胸膜：纵隔小淋巴结影41例(89.13%)，胸膜增厚或毛糙38例(82.61%)，食管扩张11例(23.91%)，单侧少量性胸腔积液1例，纵隔气肿1例。

A:A valved respirator is designed to allow for easy exhalation through a one-way exhalation valve.

答：带呼气阀的呼吸防护口罩，其设计是靠一个单向开启的阀，直接将呼气排出口罩之外。

When the subject exhaled maximally, not all of the gas was expired from the lungs.

当这种东西最大限度地呼气时，不是所有的气体都从肺里呼出。

Every breath He exhaled had water vapor in it and carbon dioxide, atoms and molecules that HAD BEEN PART OF HIS BODY.

每呼气他呼出了水汽在它和二氧化碳，原子和分子已被他的部分身体。

Objective:To observe the effct of helium-oxygen mixture on vital capacity and to evaluate the theory and application of maximal expiration flow volume curve breathing helium-oxygen mixture.

目的 ：观察氦氧混合气对肺活量的影响，并根据实验数据对氦氧混合气最大呼气流速-容积曲线的理论和价值作一评价。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
