We have demonstrated the reliability of the planimetric method for the determination of total lung capacity (TCL) in children aged 4-16 in comparison with TLC measured by the plethysmography method. We have found power function formulas to be of greater potential usefulness than linear, logarithmic or exponential formulas for calculating TLC by the planimetric technique.
我们已经证明，与通过体积描记法测量的肺总量（TLC）相比，平面测量法测定4至16岁儿童肺总量（TCL）的可靠性。我们发现，对于通过平面测量技术计算TLC而言，幂函数公式比线性、对数或指数公式更具潜在实用性。
