─—报导了在４４４位年龄范围很宽的受试对象的头部位置的力阻抗测量结果，取得频率由１００Ｈｚ到１００００Ｈｚ的数值曲线，揭示了共振频率对年龄的依赖关系，并导出其对应的统计的数学表达式。实验结果与国外有关文献作了对比。
─ ─ reported in the 444 subjects in a wide range of head force impedance measurements, the frequency obtained from 100Hz to 10000Hz numerical curve reveals the resonance frequency dependence on age and derived its corresponding Mathematical expressions of statistics. The experimental results are compared with those of foreign literature.
