1.Research and development(R&D)and the challenges of raw materials for medical additive manufacturingrnRaw materials for medical additive manufacturing have a wide range of commonalities that are also seen in many other fields,making them an important basis in the field of three-dimensional(3D)printing.Problems and challenges related to material types,powder properties,formability,viscoelasticity,and so forth also share common features.For example,many metal materials are used in the field of aviation,while metals,polymers,and inorganic materials are used in the field of biomedicine.The most widely used materials in biomedicine are biocompatible.Various homoge-neous and non-homogeneous composites are also available for 3D printing,and impose an additional challenge in additive manufac-turing;the use of heterogeneous composites in 3D printing is particularly challenging.

1979年9月里一个深夜，赵丹家里的电话铃声突然响起。上海市有关部门通知他：他从前的朋友唐纳先生回来了！根据有关部门的安排，赵丹和夫人黄宗英得以在次日前往上海东湖宾馆探望唐纳。但是有关部门又根据唐纳的叮嘱，对赵丹特别的关照说，最好不要把唐纳先生来上海的消息，转告给其他人，以防引起不必要的麻烦。那天夜里，赵丹高兴得难以成眠。 次日上午，当赵丹和夫人黄宗英在上海东湖宾馆一间恬静套间里，见到阔别多年的

【摘 要】高校学生骨干是指大学阶段在学生党团组织、社团组织、学生会以及班级中担任重要决策、组织以及管理工作的学生。区别于一般概念上的学生干部，学生骨干是学生干部中担任比较重要职务的学生，其外延小于学生干部。因其特殊身份，学生骨干会在潜移默化中影响一大批普通学生，其自身发展也在很大程度上关乎社会的未来发展。但在笔者的工作环境中，却有为数不少的学生骨干存在发展困惑，集中表现在学习与工作的平衡关系上。他
