它的吸气、压缩、排气三个连续过程是靠转子、星轮旋转时产生周期性的容积变化来实现的。
Its inspiration, compression, exhaust process is on three consecutive rotor, when rotating stars round of cyclical changes in volume achieved.
结果发现在吸气期，其气流与肺容积曲线图有明显之截平现象。
The spirometry indicated remarkable flattened inspiratory loops on the flow volume curve while he was experiencing acute symptoms aggravated by an exercise test.
残气容积（RV）与吸气相中肺野平均肺密度极显著相关（P<0.01），与上、下肺野及全肺则为显著相关（P<0.05）。
RV correlates extremely significantly with the middle lung field on inspiratory HRCT(P<0.01) , significantly with the upper, lower lung field and overall lung(P<0.05).
结果呼吸含60%氦的氦氧混合气体后，肺活量、补呼气容积呈大幅增加，深吸气量呈轻微下降变化，其中补呼气容积前后变化具有显著差异（P<0.05）。
Results: After breathing He-O2 containing 60% helium, VC and ERV increased enormously, while IC decreased mildly, among which the change of ERV showed significant difference (P<0.05).
