想念漫游 - 王贰浪

In this article, we introduce a new family of sense preserving harmonic mappings f in the open unit disk and prove that functions in this family are close-to-convex. We give some basic properties such as coefficient bounds, growth estimates, convolution and determine the radius of convexity for the functions belonging to this family. In addition, we construct certain harmonic univalent polynomials belonging to this family.

信息技术是小学教学体系的重要组成部分，对小学生而言，信息技术教学应讲求趣味性，不但能吸引学生的注意力，提高持久性，还能激发兴趣，自主挖掘知识的魅力。本文结合笔者多年的小学信息技术教学经验，探讨小学信息技术教学中游戏教学法的应用。
