The surface pressures of human surfactant films were measured under static conditions and under dynamic (expansion-compression) conditions. The results from both methods showed that the maximum surface pressures generated by surfactant films in vitro were strongly dependent on temperature throughout the range 29-41 degrees C, higher pressures being achieved at the lower temperatures. In contrast, increasing the pH of the subphase stepwise over the range 7.1-7.7 produced a modest fall in the maximum pressures exerted by the films. The possibility that surfactant films may behave in a similar manner in vivo is discussed.
在静态条件和动态（膨胀-压缩）条件下测量了人表面活性剂膜的表面压力。两种方法的结果均表明，在29 - 41摄氏度的整个温度范围内，表面活性剂膜在体外产生的最大表面压力强烈依赖于温度，在较低温度下可达到更高的压力。相比之下，将亚相的pH值在7.1 - 7.7范围内逐步升高，会使膜施加的最大压力适度下降。文中讨论了表面活性剂膜在体内可能以类似方式表现的可能性。
