【摘要】 本文发现，Ｌ／Ｈ的值有两种：一种是胸前极间距离Ｌ＿１与身高Ｈ之比，另一种是胸背极间距离平均值Ｌ与Ｈ之比。国人目前关于Ｌ／Ｈ的报导，与Ｓｒａｍｅｋ的０．１６８不同，其原因是测量极间距离的方法不同产生的，并不是中国人与外国人的体型差别引起的。在心搏出量的非线性公式中，用０．１６８Ｈ代替Ｌ更为合理。更多还原

【Abstract】 This paper had discovered that thereare two sorts of L/H ratio :L₁/H and L/H. In theformer,L₁ is the distance between the voltage elec-trodes in the front of the thorax, Another,L is aver-age distance between the voltage electrodes in thefront of the thorax and in the back. At present theL/H ratio reported by Chinese is different fromSramek’s 0.168.The difference is caused by the dif-ferent method measuring the distance betvveen thevoltage electrodes, but that isn’t caused by the dif-ferent body form of Chinese and foreigner. In nonlin-ear stroke volume formula, the substitution of 0.168H for L is even more reasonable.更多还原
