  strategies
We consider two strategies for scaling the terms in the iteration step: Norm scaling, where in each step the windows are normalized, and initial scaling where we only scale in the very beginning.
      
Beginnings have been made by firms and research organizations to confront the challenges ahead by increasing R>amp;amp;D investment, patenting activity and adopting novel strategies.
      
As in the paper of Xu Wensheng and Chen Shuping in JAMS(B), where an analogous problem in finite horizon is studied, optimal strategies are obtained via Hamilton-Jacobi-Bellman (HJB) equation which is derived from dynamic programming principle.
      
Armijo-type line search and trust region strategies as well as Fukushima's differentiable merit function are incorporated into the method.
      
Impact of operating costs on investment strategies in new technology adoption with a further new technology anticipated

Chairman Mao taught us, "One should seriously sum up one's experience." Looking back at the experiences of our own and of others in the past decade or so on the total synthesis of proteins and polypeptides, we have analyzed the inherent contradictions of the two alternative routes of synthesis on the basis of the dialectical viewpoint of "one divides into two". Either the solid phase or the solution synthesis is fraught with difficulties when the target exceeds 100 amino acids. A new synthetic strategy was developed which we believe could resolve the contradictions inherent in the synthesis of large peptides-the solid phase stepwise condensation of peptide fragments instead of amino acids. Following repeated practice guided by the spirit of independence and self-reliance, we succeeded in synthesizing first of all a new supporting medium which provisionally met our requirements. We shall describe in the present paper the successful total synthesis of the nonacosapeptide glucagon using this supporting medium. Four peptide fragments (5, 6, 9, 6), synthesized with the aid of classical methods, were coupled stepwise to a resin-bound tripeptide, with an efficiency of over 95% for each step. After treatment with hydrogen fluoride and purification twice by means of column chromatography, rhombic dodecahedral crystals of glucagon could be obtained which were identical with natural products in respect of amino acid composition, chromatographic and discelectrophoretic behaviour, etc. The overall yield was about 17%. In view of the characteristic abundance in glucagon of various kinds of functional groups which impart unfavourable obstacles to the course of synthesis, this relatively high yield and the ease with which crystalline products could be obtained testify to the potential of the new technique in the eventual total synthesis of larger proteins.

遵照毛主席关于“要认真总结经验”的教导,作者在回顾十年来多肽合成发展过程的基础上,运用一分为二的唯物辩证观点分析了目前已有的两类合成方法都难以合成含100个氨基酸残基以上的大蛋白质的内在矛盾,指出了可能解决矛盾的途径之一,一个新的合成方案——片段固相缩合法。在“独立自主、自力更生”方针的指引下,通过反复实践,我们合成了初步满足新方法所需要的新材料——表层树脂。本文报导合成胰高血糖素(29肽)的结果,目的是对新方法进行一次考验:先将用经典法合成的四个肽片段(5,6,9,6)在三肽树脂上依次进行缩合,每次缩合率皆达95%以上,全合成以后经过氟化氢处理,两次柱分离纯化,便可获得氨基酸组成、层析及碟状电泳等物化行为与天然品相同的,具有高效增血糖活力的胰高血糖素结晶——正交十二面体。全过程总得率可达17%。根据在胰高血糖素的组成中含有侧链功能团氨基酸较多的特点,在虽然给人工合成过程带来不利影响的情况下仍能获得较高缩合率及通过简单分离即能纯化结晶的结果,说明这一方法有可能为人工合成具有严格结构的较大蛋白质提供一条发展途径。

A brief description of an automatic programming system is given in this paper.A number of general formalized programming strategies are presented, which incombination with a set of rules for the formal derivation of programs given in [1]will serve as a foundation for a goal-dirrected automatic programming system. In theconstructing process of several programs, their applicability is illustrated. The methodby means of which the program is abstracted is described as well. The generalizationof programs is discussed. A theorem about a class of equivalent program schemas hasbeen proved and an algorithm for generalizing this class of program schemas has thusbeen brought forth.

本文描述一个自动程序设计系统的梗概。给出了一系列常用的形式化程序设计策略,它们连同[1]中所给出的形式推导程序规则,构成一个目标导向的自动程序设计系统的基础,并通过几个程序的构造过程,指出它们的适用性。阐述了把程序进行抽象的方法,讨论了程序的推广。证明了关于一类等价程序模式的定理,从而提供了该类程序模式推广时所用的算法。

This paper discusses the problems of Optimal lense design. In our opinion, Feder's criterion function based on similarity preseving, is more reasonable than the traditional criterionfunction based on geometrical aberrations. With regard to optimization methods, we indicate that, the damped least squares method and the new one, called "adaptive least squares method", based on the theory of numerical dependence developed by us, are more efficient. Besides, in place of weighting, we provide a strategy of...

本文就光学系统的自动设计问题进行了讨论,对于光学系统的评价,我们认为以古典的几何象差为基础的评价方法不够合理,建议采用Feder所提出的保比评价方法,在最优化方法中,着重介绍了阻尼最小二乘法以及我们所提出的以数值相关性理论为基础的自适应最小二乘法。根据我们的经验,这两种算法的效果较好。此外,我们还简化了加权的方法,而改为后期处理。最后提出了几种实施方案。
