针对学生在学习理论力学课程过程中,各章知识点、解题方法、力学建模、分析和解决综合问题不容易掌握的特点,将力学竞赛辅导采用的科学方法论中3 种逻辑方法:比较-分类法、归纳-演绎法、分析-综合法,引入到理论力学的课程教学中. 实践证明,在理论力学课程教学中,采用了这几种逻辑方法,不仅提高了理论力学课程的教学质量,激发了学生的学习兴趣;而且学生也很容易掌握各章的知识点、解题方法、力学建模,并将它们熟练地应用于分析和解决综合问题. 相似文献

现有理论力学课程英文名称普遍译成"TheoreticalMechanics".作者从课程发展的历史主线以及欧美惯用表述出发,提出对此译文的质疑,并进一步探讨分析力学在整个经典力学体系中的地位.针对我国现有理论力学教学现状,比较中美高校理论力学教学内容上的差异,呼吁在高校理论力学教学内容中增加分析力学的比重.在课程教学中,注重力学发展史主线的描绘,帮助学生树立力学学科的历史发展观,以进一步适应人才培养与时代发展需求. 相似文献

The present paper deals with development and design of new methods utilizing Wiedemann's effect for determination of state of strain in building structures. Wiedemann's effect and some features of torsional strain of magnetic field are the basis of new experimental method. Especially the point electromagnetic strain gages using the effect of pure torsion of electromagnetic field to enable universal examination. For strain-gage measurements, almost all physical quantities are used which can be related to the variation in length of the structures. From the electric strain measurements, the most commonly used methods are the measurements by resonance-wire strain gages or by electric-resistance strain gages. In this paper, electromagnetic strain gages are discussed using the Wiedemann effect, and the author describes some new measuring equipment and his own suggestions and methods based on an application of this effect. 相似文献

The exact solutions of the nonlinear equations of filtration of an aerated liquid have been obtained in [1–3]. In [4] the system of equations of an aerated liquid have been reduced to the heat-conduction equation under certain assumptions. An approximate method of computing the nonsteady flow of an aerated liquid is given in [5], where the real flow pattern is replaced by a computational scheme of successive change of stationary states. In [6] the same problem is solved by the method of averaging. In the present article estimates of the solution of the equations for nonstationary filtration of an aerated liquid in one-dimensional layer are constructed under certain conditions imposed on the desired functions. These estimates can be used as approximate solutions with known error or for the verification of the accuracy of different approximate methods. We note that the use of comparison theorem for the estimate of solutions of equations of nonlinear filtration is discussed in [7–9]. The methods of constructing estimates of solutions of various problems of heat conduction are given in [10, 11] 相似文献
