Methods: Raw,SGaw,FEV_1 and FVC were measured using body plethysmograph and after Salbutamol Aerosol were inhaled in 70 asthmatic patients,the changes of the above parameters were observed.Results: There was significant difference in Raw,SGaw and FEV_1 before and after inhalation of Salbutamol Aerosol(P.001,P.001 and P.05 respectively),but there was no significant difference in FVC.

支气管舒张试验是测定气道高反应性的标准方法之一，目前常用的肺功能参数是1 s用力呼气容积(FEV1)和用力肺活量，测定时患者需深吸气后用力呼气，易受主观因素影响，出现假象，采用体积描记仪测定气道阻力和比气道传导率则可避免上述不足。

Compared with the results of infrared polarimetry measurement,common polarimetry measurement and Ion exchange chromatography measurement,we can preliminary found that the accuracy of Near Infrared polarimetry measurement is better than common polarimetry measurement.

就糖厂中间制品的蔗糖分用近红外旋光法和普通旋光法进行了测定，并且引入离子色谱法测定作为评判，对比分析，初步得到近红外旋光法较之普通旋光法的测定准确度要高的结论。

When the pressure chamber a'nd the thermocouple psychrometer are used to determine water potential of wheat and corn leaves, the values of water potential are basically in agreement, but when they are used to determine water potential of cotton and popular leaves, the values of wheat potential are greatly different, when the dye method is used to deter...

染色法测定玉米叶水势，在高水势时其值比热电偶低，低水势下比热电偶高。虽然三种方法测定值不完全相同，但均随叶片脱水而变化。因此可用它们测定不同条件下叶片水势值的相对变化。

The method of gas chromatography has been set up under laboratory condition to determine the content of oligosaccharides (sucrose,raffinose and stachyose)in soybean products.

The two tree water consumption characteristics, Populus simonii and Robinia pseudoacacie, and the interactions mechanism with environment factors were both studied at the level of leaf and singletree in terms of the modern technology of heat pulse sap flow and thermal dissipation sap flow probe. The two main purposes of study are to provide the science evidence in estimating the ecologic water consumption rules and to arrange better densities of the two tree species stand.

本文以北京市官厅库区水源涵养林的主要造林树种：小叶杨、刺槐为研究对象，采用当前国内外最先进的热脉冲式树干边材液流测定技术和热扩散式树干边材液流测定探针测定技术，从叶片和单株水平上探讨了刺槐和小叶杨的蒸腾耗水特性以及它们与环境因子之间的影响机理，其结果不仅可为更精确地估计生态用水定额提供科学依据，而且也可为该区域这两种树种的选择及其合理林分的密度起到一定的指导作用。
