METHODS: Pulmonary function tests were performed in 20 children with asthmatoid bronchitis (2 months-2.5 years of age) before and 30, 60, and 120 minutes after salbutamo and ipratropium bromide inhalation. The indexes of pulmonary function measured included tidal breathing flow volume loop, percent of tidal volume to peak tidal expiratory flow, terminal flows per peak expiratory flow (25/PF), peak tidal expiratory flow, rate of mid-expiratory to mid-inspiratory flow, respiratory rate and tidal volume per kilogram. RESULTS: Before drug inhalation, the descending branch of the TBFV loop was depressed.

大曲的理化指标除水分、淀粉和酸度外，还有直观反映大曲发酵形态特征的指标即曲块容重，其能反映生料在制曲过程中总物质消耗量的大小，是大曲发酵成熟度的一个静态指标。

These indexes describe the fabric's thermal properties during the heated process. The heat insulation ratio preferably manifests fabric's insulation property; the difference of calefactive ratio describes dynamic conditions average calefactive case; effective thermal conductivity and compound thermal resistance are mainly considering the wholly testing characteristics and describing the compound thermal property; the response time expresses the time of step response during dynamic testing process. 3. Dynamic heat transmitting properties of fabrics and warmth retention testing methods have been developed; many different textile materials are used for actual test, and the data are analyzed, illustrated, and compared.

这些指标从不同的侧面描述了试验过程中织物试样的传热隔热性能，其中隔热率是从整体上来考虑的指标，它较好的描述了试样的隔热保温性能；升温速率差考虑的是动态变化过程中平均升温变化情况，它的大小表现了织物热性能的差异；名义导热系数和复合热阻是从试验装置的特点出发整体来考虑的热传递指标，描述了铜板、试样、铜板三者复合时的传热性能与隔热性能；而温度动态响应时间表示动态热传递过程中趋于稳态所经历的时间。
