On the Foundations of Constructive Mathematics – Especially in Relation to the Theory of Continuous Functions

We discuss the foundations of constructive mathematics, including recursive mathematics and intuitionism, in relation to classical mathematics. There are connections with the foundations of physics, due to the way in which the different branches of mathematics reflect reality. Many different axioms and their interrelationship are discussed. We show that there is a fundamental problem in BISH (Bishop’s school of constructive mathematics) with regard to its current definition of ‘continuous function’. This problem is closely related to the definition in BISH of ‘locally compact’. Possible approaches to this problem are discussed. Topology seems to be a key to understanding many issues. We offer several new simplifying axioms, which can form bridges between the various branches of constructive mathematics and classical mathematics (‘reuniting the antipodes’). We give a simplification of basic intuitionistic theory, especially with regard to so-called ‘bar induction’. We then plead for a limited number of axiomatic systems, which differentiate between the various branches of mathematics. Finally, in the appendix we offer BISH an elegant topological definition of ‘locally compact’, which unlike the current definition is equivalent to the usual classical and/or intuitionistic definition in classical and intuitionistic mathematics, respectively.     

小样本参数估计算法及其应用

本文简要介绍了Minimax法和MSAR法对小样本数据的研究,随之重点介绍了1种实用的新算法IMSAR法及其应用。该法是通过变权松弛最小二乘法,确定适当的权因子来实现的。它克服了MSAR法的运算量随样本数据量增加而显著增加的突出缺点,仿真结果表明:IMSAR法具有较强的抗干扰能力,可适应于噪声分布未知的情况。最后,本文将IMSAR法应用于转炉炼钢动态模型及药物房室模型的建立,收到了令人满意的效果。

钢坯磨削温度的若干试验研究

通过使用“可磨式”人工热电偶进行的不同条件下的磨削温度测量试验研究了钢坯磨削工件表层温度,结果表明钢坯被磨削表层温度分布与热强呈三角形分布时的理论分析结果相同,表层峰值温度随磨削压力及磨削功率增大而提高,且随工件进给速度提高而略有降低,峰值温度还随磨削角度减小而提高,90°磨削的峰值温度比0°磨削要低250℃左右,砂轮种类也对峰值温度有重要影响,使用锆刚玉砂轮时磨削温度低于棕刚玉砂轮,试验结果表明高效钢坯磨削的磨削区温度远比普通磨削为高,可达1200℃左右,还从不同方面探讨了磨削高温对钢坯磨削的影响,认为尽管磨削高温有若干不利影响,但对高效钢坯磨削却是重要条件,上述讨论,从一个方面揭示了钢坯磨削机理,并验证了关于钢坯磨削温度的理论分析结果。     

A novel mechanism for jumping in the indian ant<Emphasis Type="Italic">Harpegnathos saltator</Emphasis> (Jerdon) (Formicidae,Ponerinae)

The Indian antHarpegnathos saltator may be unique among insects in using its jumping capacity not only as an escape mechanism but also as a normal means of locomotion, and for catching its prey in flight. High-speed cinematography used to analyse the various phases of the jump suggests thatHarpegnathos employs a novel jumping mechanism to mediate these behaviours: namely the synchronous activation of its middle and hindlegs. Electrophysiological recordings from muscles or nerves in pairs of middle and hindlegs show remarkably synchronous activity during fictive jumping, supporting the synchronous activation hypothesis.Harpegnathos is not the only ant to jump, and a cladistic analysis suggests that jumping behaviour evolved independently three times during ant evolutionary history.     

抗人绒毛膜促性腺激素（HCG）单克隆抗体的研制和特性分析

以HCG为抗原,免疫BALB/c小鼠,取其脾细胞与小鼠Sp2/0—Ag14骨髓瘤细胞融合,经反复筛选和再克隆化,获得8株能稳定分泌抗HCG特异单克隆抗体的杂交瘤细胞株。对其中6个高效价单抗进行了特异性和抗原决定簇检测,选出两个抗相距较远不同决定簇的单抗(2D_4,4F_4)作进一步特性分析。结果显示:免疫球蛋白亚类鉴定,2D_4为IgGl亚类,4F_4为IgG2a亚类;亲和力常数(K_(affi)),2D_4为5.41±0.94×10~(-10)mol/L,4F_4为1.37±0.33×10~(-9)mol/L。证实该两种单克隆抗体可用于研制有关临床诊断试剂盒。     

极值原理统一的一种可能形式

本文注意到最小作用量原理,费马原理,H定理和最小熵产生原理等等最小最大原理之间的差别和联系,以变分法为工具,通过考察最小熵产生原理及H定理的另一种形式,得出与最小作用量原理,费马原理相似的结论：真实运动都是以某物理虽取极值,同时还研究了各极值原理的内在机制,找出各极值原理相似的物及根源,这样不但从数学形式上而且从内部的物理机理上将他们统一起来。
