通过直接测量在平行平面之间压缩单个未受精的 A. punculata 卵所需的力和测量压缩卵的形状，计算出内部压力和表面力。初始压力为40达因/厘米2，初始表面力为0.08达因/厘米。随着表面积因变形而增加，表面力的增加表明存在拉伸的弹性膜，而不是蛋表面的界面张力。
From direct measurements of the force required to compress single unfertilized A. punctulata eggs between parallel planes and measurements of the form of the compressed eggs, the internal pressures and the surface forces have been computed. The initial pressure is 40 dynes/cm.2 and the initial surface force is 0.08 dyne/cm. The increase of the surface force as the surface area is increased by distortion points to the presence of a stretched elastic membrane rather than an interfacial tension at the egg surface.
