建立了无限大各向同性线弹性固体中三角形位错环位移场的无坐标表达式。为了数值计算的目的，本公式可能比Hirth和Lothe（1982）先前给出的公式更有用，因为在处理“立体角”对位移场的贡献中出现的反三角函数分支时不需要特别注意。所建立的计算立体角的方法同样适用于各向同性弹性固体中的三角形环。
A formula is developed, in coordinate-free form, for the displacement field of a triangular dislocation loop in an infinite isotropic linear elastic solid. For purposes of numerical calculations, the present prescription may be more useful than one given previously by Hirth and Lothe (1982), since no special care need be taken in dealing with the branches of inverse trigonometric functions which appear in the ‘solid angle’ contribution to the displacement field. The method developed for computing the solid angle is also valid for a triangular loop in an an isotropic elastic solid.
