关于Sikkema—Bernstein多项式导数的迭代极限

本首先给出了Sikkema-Bernstein多项式的迭代极限及误差估计；然后构造一个整系数Sikkema-Bernstein型多项式，并给出了该多项式的导数逼近导函数是有界变差时的收敛阶估计式。     

优化问题的新步长法则

The step-size procedure is very important for solving optimization problems. The Armijo step-size rule, the Armijo-Goldstein step-size rule and the Wolfe-Powell step-size rule are three well-known line search methods. On the basis of the above three types of line search methods and the idea of the proximal point methods, a new class of step-size rules was proposed. Instead of a single objective function f, f ＋1/2（x - xk）^TBk（x-Xk） was used as the merit function in iteration k, where Sk is a given symmetric positive definite matrix. The existence of the steplength for the new rules was proved. Some convergence properties were also discussed.     

阵列的随机指标部分和的弱大数定律

在较一般的条件下研究了加权阵列的随机指标部分和1/(bn) sum from i=1 to Nn ani(Xni-E(XniI(|Xni|≤bn)|Fn,i-1))的弱大数定律,其中{Xni,i≥1,n≥1}为随机变量阵列,{Nn,n≥1}是正整数值的随机变量,{bn,n≥1}是正的常数.

Convergence of national science and technology policies: the case of Finland

It is a commonly held view that differences in national histories, cultures, political contexts, and the timing of a country’s entry into the industrialization process are reflected as diversity among countries in their goals, priorities, boundaries, directions, ranges, instruments and also in the performance of science and technology policy. This article, which examines development processes of Finnish science and technology policy, concludes that instead of divergence there is such startling convergence of organizational forms and practices. Finland has largely adopted its policy doctrines and instruments from the countries, which from the Finnish perspective, have been considered legitimate and successful.     

期刊全流程数字出版探索与实践 ——以《光学学报》为例

随着互联网技术的不断发展,科技期刊面临重要转型。如何推动科技期刊数字化出版建设、媒体融合发展,快速提升期刊的影响力成为一个重要课题。本文以融媒体技术手段为依托,详细总结了期刊在选题策划、稿件处理、多模式出版、融媒体服务等方面的数字化建设经验,以供其他科技期刊学习和借鉴。     

洪秀全妇女思想之"耶儒合流"——以"一言两书"为例

《劝世良言》、《钦定旧遗诏圣书》和《钦定前遗诏圣书》对洪秀全思想影响巨大,洪秀全"男女平等"思想、禁止奸淫妇女和反对淫乱思想、"为妇之道"思想、多妻制思想、对待女奴婢的思想以及妇女贞节观皆同这三本书有着直接的渊源关系,它们是洪秀全"耶儒合流"思想的主要来源.但从实质上看,洪秀全的妇女观仍然是中国传统的封建伦理道德观,而且在西方上帝的宗教招牌下有过之而无不及.洪秀全不可能具有男女平等的思想.
