摘要
本文描述了激励、检测在体皮肤谐振频率的方法。根据幅频曲线计算出皮肤的能量耗散数。获得了不同年龄的皮肤耗散数。对皮肤受乳膏和酒精处理后,利用该法对能量耗散数的影响也进行了评价。
In order to evaluate the mechanical behavior of skin in vivo,a technique for ex- citing,detecting and measuring the resonance frequency of skin is described.For this purpose,a device used to pass waves of predetemined frequency through skin is designed and a method for computicy the energy absorbed by the skin is introduced.The normal and dry skin were tested for evaluating the effect of various treatments on skin softness.
