依依不舍情，千里共云端

时光太瘦，指缝太宽。三年的时光悄无声息地流淌，不经意间迎来了和研三同学说再见的时刻。三年前，缘分使然，我们在工大相聚，一起奋斗，同长共进。三年来，大家在校园内呼吸着自由的空气，恣意挥洒着青春活力与激情，欢快的笑声在学校上空萦绕。我们共同经历了独上高楼，望尽天涯路的彷徨；为文章消得人憔悴的坚持以及文章接收后蓦然回首，成功就在灯火阑珊处的喜悦之情。风雨过后，终会见彩虹。国家奖学金，学业奖学金，省优秀毕业生以及答辩成绩优秀等诸多荣誉和奖励都是对大家努力的最大认可。课题组团结互助、积极向上的合作意识让彼此结下了浓浓的师生情和同学情。这种深情厚谊随着时间的流逝将会历久弥新。

 你们三年的研究生经历必将成为人生一段难忘的经历，永恒地镌刻在脑海中。多年后回想这段时光，注定是一段美好的回忆。青春因磨砺而出彩，人生因奋斗而升华。明天大家就将踏上新的征途，去践行各自的人生理想与抱负。桐花万里丹山路，雏凤清于老凤声。我相信：假以时日，大家一定会在各自的岗位上做出一番不平凡的业绩。桃李春风一杯酒，江湖夜雨十年灯。让我们一起向未来！他日江湖相见，每个人都会了不得！最后一首打油诗送给各位毕业生（每位同学的名字均嵌入其中）

夏日晚风凉意浓

欢声笑语映黄童

青春时光贵如珍

三年学业终有晴

菁菁校园斗芳菲

心之所骛永不停

体魄康健向未来

无限风光在险峰
