摘　　要：人体新鲜骨骼是各向异性，非均匀材料，其截面几何形状比较复杂。因此，进行应变测量时，应用常规的杠杆引伸仪，受到安装方式和测量标距等条件的限制，往往只能测量轴向一定范围内的平均应变。用电测法进行测量，可克服上述弱点，能较方便准确地测量出任意部位的一点处、任意方向的应变。这对骨骼机械性能的测定，有关生物力学问题的研究，都具有实际意义。Human living skeletons are anisotropy material,they cross section geometric shape is comparatively complicated. So, in the process of strain-measuring,when we apply the normal lever extension meter, it is confined by conditions, such as the install pattern, measurement standard and so on.It can only measure the axial direction even strain in some scope. But using Electrical Measurement method can overcome these shortcomings. It's able to measure the strain on any point and in any direction of any part accurately and conveniently. There is actual significant in both the measurement of the mechanical properties and the research about the biomechanics.
