健康长寿是自人类诞生在这颗星球上便有的永恒追求。为满足这种追求，人类花费了大量时间和精力开展相关研究。现在，人类研发出了大量医疗器械和药物，以实施精准医疗。我们不但对人体微环境有了相当透彻的了解，而且也已经对开展分子水平诊疗游刃有余。目前，人类的平均寿命已经明显延长，健康状况也得到了根本改善。

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.
