在国际竞争日益激烈的当今世界,各国政府乃至普通百姓都越来越清楚地认识到,国家的富强,企业的兴衰,无不取决于对科学技术知识的学习、掌握及其创造性的开拓相应用。但创造能力并非天生就有的,必须通过有意识的学习和训练才能形成,数学问题的开放化正反映了这种社会需要。 In the increasingly fierce international competition in today’s world, governments of all countries and ordinary people are increasingly aware that the prosperity of the country, the rise and fall of enterprises, all depends on the application of scientific and technological knowledge, mastery and creative exploration. However, creativity is not inherent. It must be formed through conscious learning and training. The openness of mathematics problems reflects this social need.
