以加强“素质教育”为重点改革数学课教学

随着社会物质和文化生活水平的不断提高，市场经济的不断发展，以及新知识的加速积累，我国的大学教育正在从“专业教育”向“素质教育”转变，即以培养获取新知识和技术的能力为主要目标，我院是培养航空机务人才的高等军事院校，培养目标的针对性强，第一任职能力要求高，

On n-relator 3-manifolds Which Are Handlebodies

Let H be a handlebody, y = |∫1,……,∫n| a collection of 2-sided pairwise disjoint simple closed curves on eH. The 3-manifold obtained from H by attaching 2-handles to H .along the curves in y is called an n-relator 3-manifold, and is denoted as Hy. In tiffs paper, a sufficient and necessary condition for Hy to be a handlebody is described.
