摘　　要：采用现代颈椎夹板设计理论,从微观结构研究薄木层积材特性,构造新型薄木层积材颈椎夹板。文中给出模压颈椎夹板的薄木最优尺寸,求出其理论弹性模量,给出对强度产生影响的相关系数,并推导出这些系数和薄木层积材颈椎夹板的弹性模量之间定量的数学关系和力学表达式,为颈椎夹板复合弹性力学的微观力学理论提供基础,并给出试验证明。In modern biomedical technology,it is a more cutting-edge research to use biomedical materials as alternative materials for making medical assistance implements.In this paper,under the theory of modern cervical splint design,we researched the sliced veneer laminated timber cervical splint characteristics from micro-structure,and constructed a new sliced veneer laminated timber cervical splint.The paper gave the optimal size of sliced veneer of the molded cervical splint,and calculated the theoretical elastic modulus and its correlation coefficient which would impact its strength.Furthermore,we got the mechanical expression by deducing these the quantitative mathematical relation between the elastic modulus of coefficients and sliced veneer laminated timber cervical splint.This provided a basis for the micromechanics theory of cervical splint composite elastic mechanics,and provided experimental proofs.
