研究了活跃汗腺数量和皮肤电阻（ESR）之间的定量关系。使用 Netsky 棱镜技术和电子闪光摄影以适当的时间间隔记录活动腺体的数量，同时通过 Jasper 方法的修改记录相同皮肤区域的 ESR。电阻（电导）的倒数随着活性腺体数量的增加或减少而近似线性变化（代表性相关系数为 0.899 + 0.083），但上升和下降曲线的斜率和零腺体计数截距略有不同。数据表明，每个活性腺体都贡献了一条传导路径，该传导路径在电学上类似于添加与其他汗腺电阻并联的电阻，而斜率和截距的微小变化与非发汗传导路径的水合作用有关。作者得出的结论是，适当应用 ESR 方法作为衡量汗腺和催汗通路活动分级的有效性似乎已得到充分证实。
Quantitative relationships between numbers of active sweat glands and electrical skin resistance (ESR) were examined. Numbers of active glands were recorded at suitable intervals by use of the Netsky prism technique and electronic flash photography, while ESR of the same skin areas was recorded by a modification of the Jasper method. The reciprocal of resistance (conductance) varied approximately linearly with either increasing or decreasing numbers of active glands (representative correlation coefficient .899 + .083), but the rising and falling curves differed slightly in slope and zero gland-count intercept. The data indicate that each active gland contributes a conduction path that is electrically analogous to adding a resistance in parallel to other sweat gland resistances, while the small variations in slope and intercept are related to hydration of nonsudorific conduction paths. The authors conclude that the validity of appropriately applied ESR methods as a measure of gradations in activity of sweat glands and sudomotor pathways appears well established.
