 the reciprocity theorem
 The reciprocity theorem in coupled problems of viscoelastic thermodiffusion Next, we show that the reciprocity theorem leads to a two variable generalization of the quintuple product identity. We also interpret the Reciprocity theorem of electrical networks in terms of traversals in random walks. Certain applications of the reciprocity theorem to a nonhomogeneous medium with constant shear coefficient The theoretical analyses of the measurement sensitivity employ the reciprocity theorem and the lead field theory with a highly detailed, anatomically accurate, three-dimensional computer thorax model. 更多
 On applying the diffraction theory and with the aid of the reciprocity theorem, an approximate formula for the radiation field of a slot cut in a metal sheet of finite size is derived. Although the same formula can be obtained in an alternative way, the present approach is superior as far as the clarity of its physical interpretation is concerned. 本文应用绕射理论并借助于互易定理,导出了一个在有限尺寸金属平板上割出的一条裂缝的近似辐射埸公式。虽然相同公式也可以用其它方法求得,但本文方法具有物理概念清晰的优点。 An extension of the reciprocity theorem in elasticity is made to be applicable to the static, self-gravitational elastic earth. It is then used to the case when the earth is acted by bodily tide and surface loadings. "We thus obtain, from the physical point of view, six-relations between the Love numbers and surface loading coefficients. They are equivalent to the results obtained by Molodensky using purely mathematical method. 本文将弹性力学甲的能量互换定理作了推广,得到了对静态、具自重的弹性地球体适用的互换定理。文中将所得能量互换定理运用于受体潮力及表面载荷作用的地球体,从而由物理学的角度得出了Love数与表载系数之间的六个关系式,它们与Molodensky用纯数学方法所得的结果是等价的。 Motional influences in magnetic reproduction are analyzed with the aid of the reciprocity theorem of magnetic recording theory, Alternative expression for the induced READ voltage are derived for the case of a carrier (disk or tape) of spatially recorded magnetization in quasi-rigid (translatory and/or rotary) motion. 本文借助于互易理论推导出空间记录磁化强度的载体(磁盘或磁带)做准刚体运动时,输出电动势的表达式。 << 更多相关文摘
