In this paper, the specific solutions of orthotropic plane problems with body forces are derived. Then, based on the general solution in the case of distinct ei
第一节概述一、产品的多样化倾向及其原因当我们看到商店里陈列的电器产品和公路上奔弛的汽车，就会深切地感到当今的时代是产品多样化的时代。产生这种趋势的原因是：（一）消费者的
Modern automotive petrol engine performance is significantly affected by effective tune-up. Current practice of engine tune-up relies on the experience of the a
A completely open cavity, which is formed by three 60-degree wedges of a photonic crystal with negative effective index, is introduced. Such a realizable design
大学生零薪酬就业的现象越来越普遍，对于这种尴尬现象，我们必须认清这种现象背后的原因，提出解决措施，从学校、政府、个人三方面共同着手，改善大学生就业状况。
This paper presents a symplectic method for two-dimensional transversely isotropic piezoelectric media with the aid of Hamiltonian system. A symplectic system i
Digitization projects should focus on quantity rather than quality. Increasing quantities of information produce qualitatively more valuable services. Online wr
A bi-harmonic stress function is constructed in this work. Ariy stress function methodology is used to obtain a set of analytical solutions for both ends fixed
