中医学“精微”与肿瘤微创

作者通过对中医古籍的深入研究,发现中医学精微主要有具体的物质、医疗技术追求的最高目标和精确微观的观念三种涵义,认为中医的精微理论主要表达了采用精确微观的观念去着重研究具体的微观物质,其中具体物质才是医学研究的最核心内容。深入发掘精微理论的内涵可以进一步正确认识中医的宏观与微观,把中医学目前研究方向从虚无的气扩展到具体的微观物质,对于中医肿瘤微创治疗的发展具有重要意义,同时也是中医理论自身发展的新方向。

用复杂性科学原理揭示中药指纹图谱的本质特征

目的对中药指纹图谱的本质特征进行深入研究。方法从复杂性科学角度论述中药指纹图谱所具有的本质特征。结果中药指纹图谱具有系统性、特征性、相对稳健性、模糊性、整体性、复杂性、动态开放性、活性交互性、微观精确性、宏观量化特征、超信息特征和数字化特征,总计12个本质特征。结论宏观定性评价是利用指纹图谱评价中药质量的基础和前提,宏观定量评价构成了中药指纹图谱控制中药质量的高级阶段。复杂性科学是指导中药指纹图谱控制中药质量的理论精髓。

Research on surface characteristics of non-traditional finishing

This paper reports results of investigations of some surface characteristics, and resulting performance of parts proc-essed using non-traditional finishing methods. The friction factor, precision keeping and anti-conglutination performance of the finished surfaces are considered, and surface characteristics such as microtopography and machining texture were investigated. The overall performance of surfaces finished using non-traditional finishing methods was found to be significantly better than that of traditional finishing methods.
