【摘要】 在封闭体系中 ,较大的时间尺度上二次水及NaCl,HOAc ,C5H5N ,苦味酸等溶液电导率在确定的温度下不再是恒定值 ,表现出持续变化 .变化轨迹可分为电导率随时间增加而增大的水型轨迹和随时间增加而减小的吡啶型轨迹两种类型 .对比实验表明产生这两类导电轨迹的原因是由于物质对水的结构有促进能力和破坏能力两种不同功能所造成 ;而电导率持续变化的原因则可能与自然环境某些电磁辐射场强度的持续变化有关连 .

【Abstract】 In this paper, the conductivities of double-distilled water and aqueous solutions of NaCl, HOAc, C 5H 5N, etc. were determined in an elongated time period. It is found that the conductivity values of the solutions at certain temperature are not constant and change over time. On a large time scale, the variation trajectories can be divided into two groups. The one is that the conductivities increase with time increase, known as "water type trajectory"; and in the other the conductivities decrease with time increase, known as "pyridine type trajectory". Contrast experiments showed that the "water type trajectory" would be obtained with the promoter of water structure, and "pyridine type trajectory" would be obtained with damager of water structure. They would be related to the strength of electromagnetic field radiation in natural surroundings.
