The elasticity of surfactant films from the lungs of neonatal pigs was measured using a torsion elastometer. It was found that the elastic modulus of the films increased markedly as the surfactant concentration was raised. Increasing the temperature stepwise over the range 25--41 degrees C produced a decrease in the elastic modulus. In contrast, altering the pH of the subphase over the range 7.1--7.7 had no significant effect on film elasticity. The influence of surfactant films on pulmonary compliance is discussed.
使用扭转弹性计测量了新生猪肺表面活性剂膜的弹性。发现随着表面活性剂浓度的升高，膜的弹性模量显著增加。在25至41摄氏度范围内逐步升高温度会导致弹性模量降低。相比之下，在7.1至7.7范围内改变亚相的pH值对膜弹性没有显著影响。讨论了表面活性剂膜对肺顺应性的影响。
