effective contact area ratio 有效接触面积比
In order to analyzing the influents of length, width, height and effective contact area per unit volume, three kinds of fills whose character are different selected as experiment speriment.
为了研究填料的长、宽、高、比表面积这些特征尺寸对填料热质传递性能的影响，本文选用了三种不同特征尺寸的铝质填料进行冷却除湿实验研究。
Doubling hf-current results in a doubling of current density and a fourfold heat provided that the area of effective contact between the tissue ang the electrode remains constant.
如果人体组织和电极之间的有效接触面积保持不变，那么高频电流强度扩大一倍将会使电流密度增大一倍，并产生四倍的热量。
This results in a fourfold increase of heat Correspondingly, heat drops by 75% if current density is reduced by half, e. g. by doubling the effective electrode contact area.
相应地，如果将有效的电极接触面积加大一倍，电流密度将减少一半，热量则减少75%。
