The elastance of the midthoracic portion of the oesophagus was measured in 14 healthy Dutch Friesians. These were divided into three groups with mean ages of six, 126 and 1636 days, respectively. Mean elastance was 0.17, 0.10 and 0.06 kPa ml-1, respectively. The calculated percentage of error, in relating the endoesophageal pressure with that in the thorax, was found to be smaller than 1 per cent for each animal.
在14头健康的荷兰弗里斯兰奶牛中测量了食管胸段中部的弹性。这些奶牛被分为三组，平均年龄分别为6天、126天和1636天。平均弹性分别为0.17、0.10和0.06 kPa ml-1。计算得出，将食管内压力与胸腔内压力相关联时，每头动物的误差百分比均小于1%。
