中文摘要 | 本研究中推導出彈性超導體之變分原理,從而得到描述彈性超導行為之御制方程 式與邊界條件。此處並詳細探討由複內變數及向量勢所引發之規範問題。避開規範問題之另 一取代方法亦在此處提出,其可行性將予以解釋。結果證明由變分原理所得之方程式與由不 可逆熱力學方法之結果是相同的。 |
英文摘要 | The purpose of this paper is to formulate a variational principle which yields the system of field equations and boundary conditions describing the behaviors of the elastic superconductor. The gauge problem which arises from the complex internal variable and vector potential is discussed in detail. An alternative that parries the problem of complex numbers is proposed, and its feasibility is also explained. The results are also shown to be consistent with those obtained by the continuum mechanics approach. |
