在这项研究中，我们研究了从胫骨远端的湿人类皮质骨和松质骨组织的电特性及其与湿，干，灰组织密度的关系。皮质骨和松质骨的电阻率和比电容被确定为不同的频率和方向（方向）。测量骨样品的湿、干和灰分组织密度，并确定灰分含量。相关和回归分析被用来检查松质骨和皮质骨标本的电性能和组织密度之间的可能关系，以及为所有的骨标本组合。骨湿密度与骨干密度、骨灰密度呈极显著正相关（P<0.001）。松质骨标本在所有三个正交方向上的比电容与湿密度、干密度和灰分密度呈显著正相关（p<0.01）。在一般情况下，比电容更多地依赖于所有的骨标本的密度，只有一个弱的关系，发现人类皮质骨的电阻率和密度之间。
In this study, we examined the electrical properties of wet human cortical and cancellous bone tissue from distal tibia and their relationship to the wet, dry, and ash tissue densities. The resistivity and specific capacitance of both cortical and cancellous bone were determined for different frequencies and directions (orientation). The wet, dry, and ash tissue densities of the bone samples were measured, and the ash content was determined. Correlation and regression analysis was used to examine the possible relationships among the electrical properties and the tissue densities for cancellous and cortical bone specimens separately as well as for all of the bone specimens combined. Highly significant positive correlations (p<0.001) were found between the wet density of bone and the dry and ash densities. The specific capacitance of the cancellous bone specimens in all three orthogonal directions showed significant (p<0.01) positive correlations with the wet, dry, and ash densities. In general, the specific capacitance depended more on density for all bone specimens, and only a weak relationship was found between the resistivity of human cortical bone and density.
