针对提高专业学位硕士研究生培养质量,提出了深度融合“理论知识（理）、专业技能（技）和情感价值观（情）”培养理念的专业课程建设方法,并以火箭军工程大学航天工程方向新增专业学位研究生课程“固体火箭发动机结构完整性分析”为例,紧密围绕“怎么融”这条主线,以“融什么、谁来融”为两翼,分别从“理技情”融合培养理念的内涵和理、技、情元素挖掘,融合“理技情”培养理念的教学思路和实施,以及课程教学团队改革三个方面,阐述了如何融合“理技情”的“三位一体”培养理念进行课程建设,以期为专业学位硕士研究生的课程改革和培养方法探索等提供借鉴和参考。 相似文献

A meshless local discontinuous Petrov-Galerkin (MLDPG) method based on the local symmetric weak form (LSWF) is presented with the application to blasting problems. The derivation is similar to that of mesh-based Runge-Kutta Discontinuous Galerkin (RKDG) method. The solutions are reproduced in a set of overlapped spherical sub-domains, and the test functions are employed from a partition of unity of the local basis functions. There is no need of any traditional non-overlapping mesh either for local approximation purpose or for Galerkin integration purpose in the presented method. The resulting MLDPG method is a meshless, stable, high-order accurate and highly parallelizable scheme which inherits both the advantages of RKDG and meshless method (MM), and it can handle the problems with extremely complicated physics and geometries easily. Three numerical examples of the one-dimensional Sod shock-tube problem, the blast-wave problem and the Woodward-Colella interacting shock wave problem are given. All the numerical results are in good agreement with the closed solutions. The higher-order MLDPG schemes can reproduce more accurate solution than the lower-order schemes. 相似文献
