现在一个公认的事实是，细菌生长的物理条件的变化可能显著地影响它们的活动。温度变化、各种离子浓度、渗透压和许多其他因素的影响已经被研究过。然而，有一种物理力尚未得到充分的研究，即由分子之间的相互吸引产生的力，它表现为表面张力。细菌学家越来越相信，对许多迄今知之甚少的现象的解释可能依赖于对表面力作用的了解。根据麦卡勒姆的说法，1“表面张力是动物和植物细胞生命中最强大、最重要的力量。”
It is now a well established fact that changes in the physical conditions under which bacteria grow may markedly affect their activities. The effects of variations in temperature, concentrations of various ions, osmotic pressure and numerous other factors have been investigated. There is one physical force, however, which has not been adequately studied, namely, the force that arises from the mutual attraction between molecules and manifests itself as surface tension. Bacteriologists are coming more and more to the belief that an explanation of many hitherto little understood phenomena may rest on a knowledge of the action of surface forces. According to MacCallum,1 "surface tension is the most powerful and most important of all forces concerned in the life of animal and vegetable cells."
