• 摘要

周毓麟院士是首届CSIAM苏步青应用数学奖特别奖的获奖人，他是中国大规模科学与工程计算、非线性偏微分方程领域的著名专家和先驱者之一。他的理论研究成果系统而深刻，他提供的方法有力地指导和推动了包括核工程在内的许多实际问题的计算。他培养的学生有许多成为偏微分方程、计算数学及工业应用中的学术带头人。
 
       周毓麟院士对科学计算的重要贡献还包括：他通过建立计算机舍入误差积累的概率模型，提出了计算机字长与速度、内存匹配关系的计算公式。周毓麟院士对计算机设计中网络的拓扑结构问题进行了研究，给出了关于网络和乘积网络平均短程的计算公式。
 
       基于周毓麟院士在核科学中的数学以及偏微分方程、计算数学、计算机应用等多个领域取得的杰出成就和做出的重大贡献，2006年8月在南京召开的第一届CSIAM苏步青应用数学奖颁奖大会上，授予周毓麟院士首届CSIAM苏步青应用数学奖特别奖。
 
       周毓麟，1923年2月出生于上海，1945年毕业于大同大学数学系。早年从事拓扑学研究，1954年赴莫斯科大学留学，主攻非线性偏微分方程，1957年获物理数学科学副博士学位后，回北京大学数学力学系工作，1960年奉调参加我国的核武器理论研究。曾任北京应用物理与计算数学研究所副所长、中国工程物理研究院科技委委员以及中国计算数学学会理事长和名誉理事长等职。1991年当选为中国科学院学部委员（院士）。周毓麟院士是我国核武器设计中数学研究工作早期的主要组织者和开拓者之一，为我国核武器事业的发展作出了重大贡献；在非线性偏微分方程领域，他是我国早期的主要开拓者之一；基于科学计算实践，他建立了离散泛函分析的方法和理论。
 
       他热爱科研，更热爱祖国，曾几次为了国家需要转换专业方向，“为国家建设选择研读偏微分方程，然后为国防搞差分，后来又从国家建设需要出发再回去搞偏微分方程”。有人觉得这是牺牲和奉献，但他却认为是对自己的提升：“国家需要我，是我的荣幸。实际上，我也总是想从更广阔的视野上，不断提高自己对数学的认识。这一点是推动我勇于去改变、去做研究的动力。”

“当前，我国科技教育界的青年科技人员承受着续聘、升职等多重压力。过重的压力不利于他们安心工作。这将严重影响我国广大青年科技人员在学术方面的健康成长，进而影响我国科学技术的发展。”全国政协委员、中国科学院院士袁亚湘说。
 
       拥有一支高水平科技人才队伍是科技强国的关键。但目前，一些刚刚入职的青年科技人员没有受到应有的重视。此外，不少单位为了追求科研产出，给科技人员压任务、定指标，对科技人员续聘、升职等也设立了“高门槛”。但这种算“工分”的做法显然不是国际学术界通行的做法，也不符合科学技术的实际发展规律。袁亚湘告诉《中国科学报》，此种“工分”式考核标准会让青年科技工作者“急功近利”、追求数量，不利于引导他们潜心研究、默默奉献，也不利于他们健康成长、系好科研生涯的第一颗“纽扣”。
 
       袁亚湘认为，在缺乏良好科研环境的前提下，国内优秀的青年科研人员很难安心研究重大问题和原创性科学问题。这将严重影响我国科学研究，特别是基础研究的良性发展。为此，他呼吁各部门、各单位高度重视普通青年科技人员，关心他们的成长，为他们营造良好环境。
 
       基于此，袁亚湘建议，首先高等学校、科研院所不应对聘用的青年科技人员设定一些不合理的定量考核指标（如发表文章数）；其次应参照国际学术界通行的终身教职制度，给予新招聘的青年科技人员相对长的初始聘期（6年），并使其拥有宽松的科研环境，初始聘期结束后可参照国际通行的终身教职评审方式决定是否续聘。
 
       此外，要减少“帽子”工程，各部门不应将精力过多聚焦于“大师”和“顶尖人才”，而应该把更多注意力放在广大科技工作者，特别是千千万万没有“帽子”的青年科技工作者身上。

• 摘要

Computational Science and Engineering (CSE) complement theory and experiment as a critical component of scientific discovery. At the frontiers of CSE remain many open problems and challenges, including the verification, validation, and uncertainty quantification of computational models; the analysis and assimilation of large and complex data sets, including techniques for visualization and animation; and the design of flexible CSE software.
 
The SIAM CSE conference seeks to enable in-depth technical discussions on a wide variety of major computational efforts on large-scale problems in science and engineering, foster the interdisciplinary culture required to meet these large-scale challenges, and promote the training of the next generation of computational scientists.
