Phonatory airflow was recorded in 361 laryngeal disease patients and 59 normal subjects by using a constant temperature anemometer to measure Isshiki's proposed parameter, the AC/DC percentage. The pathologic groups displayed AC/DC percentage values smaller than those of the normal group. The value differentials observed among the various diseases suggest that the AC/DC percentage may reflect the vibrational capacity of the vocal cords.
通过使用恒温风速计测量石木提出的参数——交流/直流百分比，记录了361例喉疾病患者和59名正常受试者的发声气流。病理组的交流/直流百分比值低于正常组。在各种疾病中观察到的值差异表明，交流/直流百分比可能反映声带的振动能力。
