冯康先生是我的老师,他去世至今已有12年了.由于他对科学事业、特别对计算数学与科学计算事业的杰出的历史性贡献,我们至今还经常提到他的名字并深切怀念他.近年来我曾先后应邀在北京、上海、江苏、山东、湖南等省市的十几所高等院校为研究生、本科生及青年教师做专题报告,介绍 Mr. Feng Kang, my teacher, has been around for 12 years since he died, and we have often mentioned his name and deeply missed his distinguished contribution to the cause of science, especially to the computational mathematics and scientific computing. In recent years, I have been invited to do special reports for graduate students, undergraduates and young teachers in more than a dozen colleges and universities in Beijing, Shanghai, Jiangsu, Shandong and Hunan provinces and cities
