  1. Several subclassifications have been proposed : simple chronic bronchitis describes a condition characterized by mucoid sputum production ; chronic mucopurulent bronchitis is characterized by persistent or recurrent purulence of sputum in the absence of localized suppurative diseases such as bronchiectasis ; chronic bronchitis with obstruction deserves a separate classification characterized by presence of airway obstruction as assessed by the used of the forced expiratory vital capacity maneuver ; and chronic asthmatic bronchitis

    它可以分為以下幾種類型：單純性慢性支氣管炎，其特徵為咳粘液性痰；慢性粘液膿性支氣管炎，其特徵是反復的或持續的咳膿痰，但肺部並無化膿性病變，如支氣管擴張；慢性支氣管炎伴阻塞，其特徵為用力呼氣肺活量測定時有氣道阻塞的表現；慢性哮喘性支氣管炎，其特徵是患者有長期的咳嗽及咯痰史，后來肺部出現哮鳴者，因此與哮喘伴慢性氣管阻塞的病人不同。
  2. 3. on boiler retrofit, the calculation of fuel burning, the heat calculation of boiler inside structure and convection section, and the design of structure parameter of feed water heat exchanger are made. the flue gas channels " resistance calculation and the boiler strength verifying are also carried out. replacement of water cooling wall improves heat exchanging and decreases loss of heat radiant

    對鍋爐本體進行了燃料燃燒計算、爐膛結構熱力計算、對流受熱面結構熱力計算、鍋爐給水加熱器結構參數設計、煙道阻力計算及鍋爐元件強度校核等；改進了水冷壁布置使換熱效果更好，減少輻射換熱損失；改進對流段結構，更充分的利用爐膛出口煙氣余熱，提高熱效率；並且進行了煙氣阻力計算、熱效率計算和能量平衡測試，對改進后的稠油燃料和改進前進行了對比，燃燒狀況和熱效率有明顯改善。
  3. With the favor of these techniques, the static pressure distribution along the length and the velocity profile at the mini - channel exit were obtained. with the data of more than 500 flow states based on 13 kinds of mini straight rectangular channels that their heights were 0. 5mm and 1. 0mm, the effects of characteristic scale, surface roughness and the aspect ratio of rectangular on the characteristics of flow resistance of mini straight channels were studied

    採用在沿程測量氣流靜壓分佈、在出口測量速度分佈的方法，對高度0 . 5mm和1 . 0mm的13個微小直矩形通道的500多個狀態流場進行了測量，研究了特徵尺度、表面粗糙度、橫截面寬高比等因素對微小等直通道流動阻力特性的影響。
