The urinary flow rates of 3 normal men were measured for a wide range of bladder volumes. Linear transformation of voiding curve data indicated that the relationship between urinary flow and voided volume could be described as parabolic, hyperbolic or logarithmic. These functional relationships were found to hold irrespective of age and volume, although deviations from the calculated voiding curves occurred at higher volumes. If only voiding data for volumes less than 150 ml. were considered, then, in addition to the aforementioned mathematical relationships, the dependence of flow on volume could be described validly by a straight line function, the slope of which represents an individual's best possible voiding potential.
测量了3名正常男性在膀胱容量变化范围较大时的尿流率。排尿曲线数据的线性变换表明，尿流与排尿量之间的关系可描述为抛物线形、双曲线形或对数形。尽管在较大容量时与计算出的排尿曲线存在偏差，但发现这些函数关系与年龄和容量无关。如果仅考虑小于150毫升容量的排尿数据，那么，除了上述数学关系外，尿流对容量的依赖性可用直线函数有效描述，其斜率代表个体最佳的排尿潜力。
