The results showed that:(1) In COPD group the alveolar walls were broken. The average area of alveolars was 2.46 times as big as the control group, and the average diameter was 1.42 times as compared with the control group. As the diameter of bronchioles was less than 100μm and 100～200μm respectively, the average area of smooth muscle in bronchioles increased to 3.06-fold and 2.13-fold respectively. By electron microscopic, the proportion of Clara cells of respiratory bronchioles in COPD group decreased, the Clara cells were denaturalized, the proportion of Clara cells containing low density secretory granules increased. The airway resistance was 1.84 times while the dynamic compliance was only 70.45% comparing with the control group.

结果表明：(1)光镜下，COPD组大鼠与正常对照组比较，肺泡壁破坏、肺泡腔扩大，平均肺泡面积和平均肺泡直径分别为正常对照组的2.46倍和1.42倍，在直径＜100μm及直径100～200μm的小支气管，COPD组大鼠支气管平滑肌面积分别为正常对照组的3.06倍和2.13倍；电镜下可见，在呼吸性细支气管，Clara细胞占上皮细胞的比例下降，细胞变性，含低电子密度颗粒的Clara细胞比例增加；呼吸功能测定可见COPD组大鼠呼气相气道阻力是正常对照组的1.84倍、动态呼吸系统总顺应性为正常对照组的70.45％。

The oscillation performance of jet, as oscillation frequency, is the essential data for designing the fluidic device, which is also the key factor that influence the coupling effect of fluidic device and receiving tube. This paper does experiment on the oscillation availability and frequency of feedback jet-oscillation gas wave refrigeration. As a conclusion, the jet oscillates only in a certain range of geometrical sizes and operating conditions. Under the condition of high pressure ratio, the frequency of the jet"s oscillation is only affected by the feedback tube"s length and chamber remarkably. Under the condition of low pressure ratio, the frequency descends with rise of the pressure ratio.

本文将跨音速正反馈射流振荡器与接受管耦合，对耦合后的射流振荡气波制冷机的可振性、振荡频率以及它们的影响因素作了实验研究，得出如下结论：射流只在一定的操作条件和几何结构尺寸范围内才能稳定振荡；射流的振荡频率在较高压比下只受反馈管长和反馈管容腔大小的显著影响，在小压比下随压比的增大而增加；其它结构尺寸和操作条件只影响可振性。
