ZHANG Qin, WAN Li-ya （ Childrens Hospital of Tianjin, Tianjin 300074, China）Pulmonary function test has become an important way to diagnose respiratory system diseases,such as asthma; Bronchiectasis test is wildly used as a way to diagnose, differential diagnose bronchial tube asthma and guide the clinical treatment. Pulmonary function test using Impulse oscillometry is a technique to evaluate the airflow obstruction in respiratory diseases.

目前，临床常用扩张试验前、后第1秒用力呼气流量(FEv1)变化率作为判断指标，也有用呼气高峰流速、最大呼气中段流量变化率作为判断指标，但对于低年龄儿童来说，由于理解能力和配合能力的欠缺，上述参数作为判断气道阻力可逆性反应的指标都存在明显的局限性和一定的漏诊率u J。

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

轮南低凸起奥陶系及石炭系发育大规模的凝析气藏，地球化学的研究结果表明，这些凝析气藏中凝析油 Rc 在0.8%~1.0％（远低于热裂解成因 R o＝1.3％的门限），凝析气为过成熟干气（回归 R o＞2.0％）；同时，区内原油与干气的充注期相异，表明轮南地区的凝析气藏并非热裂解成因的产物。
