回转体零件形位误差数据处理软件包

在介绍获取采样数据方法的基础上,简要地叙述了所建立的主要形位误差的数学模型．着重论述了形位误差数据处理软件包的设计思想与实现方法．该软件包不但可以求得不存在原理误差的准确的形位误差值,而且可以求得形位误差的方位．该软件包已应用在＂ＸＷＹ－Ｉ＂型形位误差测量仪上．     

还原论思维方式的终结

“还原”一词有多重含义,通常被区分为以下三个层次：本体论还原,方法论还原和理论还原,在我看来,本体论还原不过是唯物论二,一个基本命题,而方法论还原也仅仅是分析方法,没有会么新意,实际,还原论者真正关头的是理还原,而这又被证明是失败的。因此,我主张科学在未来世纪的进步取决于人们摆脱还原思维方式的程度。

Milestone of the meridian science──970th anniversary of the Chinese Bronze Statue of Meridian

For more than a thousand years, Chinese people were aware of the transmitted sensations by the application of needles on the body surface. This practice is called acupuncture. Acupuncture had been recorded and transcribed in writings and in drawings, until finally the acupoints were inscribed onto a bronze statue. The bronze statue was called the Meridian Figure. Deeply embodied in the bronze statue is a tripartite confrontation-prism representation of the humans body. This concept was a great scientific achievement in ancient China. The author traces the history of Meridian science described in traditional Chinese medical terms. Then he explores a clear analogy of the meridian pathway (MP) phenomenon. In a model system, by using a simple segmental in vertebrate, certain parallels can be demonstrated with the meridian concept. For example, the author demonstrated a clear correlation rule among the central mechano-sensory channels, and characteristics of positional discrimination in individual nerve cells from different receptive field inputs. The evidence suggests that the MP phenomenon is an objective neurobiological response. To clarify the research objective in this paper, the author suggests that the MP is a bi-directional pathway along which a positional message signal is transmitted. This phenomenon is evoked by physical stimulation, transmitted linearly across the human body segments, and is perceived by the brain. The MP consists of low resistance paths, is connected by the liquid media contained in the apposite membranous structure. At the cellular level, the regulation functions of MP must pass through along this low resistance path. Two aspects of the modern Meridian research are the functional regulation and the mechanism of intercellular liquid modulation at the nanometer level.

科学发现及其逻辑性研究

在讨论科学发现,科学发现逻辑性研究的历史的基础上,就科学发现逻辑性研究的两个新视角作了评价和展望。“信息域”拓展了科学发现逻辑性的空间,突现出社会文化因素的意义;模糊思维把科学发现的逻辑性研究转换为对模糊信息进行加工、度量的认知过程,强化了科学发现逻辑性研究的现实性。
