论抽象在数学美中的功能与价值

一切数学对象、一种数学理论、一个数学体系的形成都是经过多级次、多层次、多种形式的抽象思维的产物,它们既揭示了各种事物数量本质和规律性,又在逻辑上的自恰性,系统的前后一贯性以及公式、定理、公理体系体现出形式上的简洁和内涵的深广。现代数学的更高的抽象程度,使数学达到了最大的简单性、统一性、纯粹性、深刻性、精巧性、严密性、清晰性、能动性。因此,数学美是一种学科美,而抽象美则是一种高度内含于数学学科的方法美。     

民营企业家体育锻炼与生活方式及健康现状的调查分析

对浙江沿海3城市(温州市、宁波市、台州市)208名(25岁～59岁)民营企业家的身体健康状况、体育锻炼情况与生活方式等进行调查,结果表明:浙江沿海3城市民营企业家身体健康状况不容乐观.体质测试总体合格率为65.86%,低于全国的合格率(71.40%)和浙江省的平均水平(79.70%).大多数民营企业家日常生活方式差,参加体育锻炼的人数少.建议民营企业家要养成良好的生活习惯,重视卫生保健知识的自我教育,积极参加体育锻炼.

Philosophy of chemistry and the image of science

The philosophical analysis of chemistry has advanced at such a pace during the last dozen years that the existence of philosophy of chemistry as an autonomous discipline cannot be doubted any more. The present paper will attempt to analyse the experience of philosophy of chemistry at the, so to say, meta-level. Philosophers of chemistry have especially stressed that all sciences need not be similar to physics. They have tried to argue for chemistry as its own type of science and for a pluralistic understanding of science in general. However, when stressing the specific character of chemistry, philosophers do not always analyse the question ‘What is science?’ theoretically. It is obvious that a ‘monistic’ understanding of science should not be based simply on physics as the epitome of science, regarding it as a historical accident that physics has obtained this status. The author’s point is that the philosophical and methodological image of science should not be chosen arbitrarily; instead, it should be theoretically elaborated as an idealization (theoretical model) substantiated on the historical practice of science. It is argued that although physics has, in a sense, justifiably obtained the status of a paradigm of science, chemistry, which is not simply a physical science, but a discipline with a dual character, is also relevant for elaborating a theoretical model of science. The theoretical model of science is a good tool for examining various issues in philosophy of chemistry as well as in philosophy of science or science studies generally.
