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.

In addition to water content, amylum and acidity, the physiochemical indexes of Daqu also include volume weight of caky starter , which is a static index of fermenting degree of Daqu indicating directly the morphological characteristics in Daqu fermentation and the consumption of raw materials in starter-making.

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.
