We have constructed the oscillating-plate viscometers with laser displacement transduser and eddy-current displacement transduser, and then the characteristics of the viscometers have been investigated experimentally over 1-10^5Pa・s at room temperature. The results have been obatined as follows :(1) Viscosities of liquids under about 10mPa・s, to which oscillating-plate methods could not be applied so far, have been measured by the above viscometers with an accuracy of (〕SY.+-.〔) 10%.(2) Although it has been pointed out that viscosity of liquid metals (having low kinetic viscosity) could not be measured by the oscillating-plate method, we have found that the above oscillating-plate viscometers could be applied to measure viscosity of liquid mercury with an accuracy of (〕SY.+-.〔) 5%.(3) If we could miniaturize the above oscillating-plate viscometers and then put it in an airtight container, we could measure the viscosities of such liquids as only a small amount, for which atmosphere have … More to be controlled strictly, and having radioactive substances. As a fundamental study on construction of small-sized oscillating viscometers, the effects of reflected wave from the wall of a vessel and surface tension of liquid specimens on viscosity measurement by the viscometers have been examined experimentally. As a results, we have found the possibility of miniturization of the viscometers by selecting adequate size of the plate and so on, e.g. frequency.In addition, we have applied the oscillating-plate viscometer to measure viscosity of standard reference materials (SRM) for the project of high temperature viscosity measurement organized by Europe Community (EC). The viscosity of SRM obtained by the above viscometers agree with the results reported by other laboratories within the spread of (〕SY.+-.〔) 25%, which is a goal set up at the beginning of the project. Incidentally, all the laboratories except us have used rotating cylinder methods.In conclusion, we have successfully developed a high-performance oscillating-plate viscometer in this work. Less

我们用激光位移传感器和电涡流位移传感器分别制作了板式粘度计，并在室温下对该粘度计在1-10^5Pa·s范围内的特性进行了实验研究。（1）用上述粘度计测量了目前不能用平板法测量的10 mPa·s以下液体的粘度，其精度为± SY.（）10%。(2)虽然已经指出，液体金属的粘度（具有低的动力粘度）不能用刮板法测量，但我们发现，上述刮板粘度计可以应用于测量液体汞的粘度，其精度为（±）SY.（）5%。(3)如果我们能把上述两种粘度计组装起来，然后把它放在一个密封的容器里，我们就能测量出这种液体的粘度，而大气对这种液体的粘度只有很小的影响。 ...更多信息 受到严格控制，有放射性物质的。作为小型振荡粘度计结构的基础性研究，实验研究了容器壁反射波和液体样品表面张力对粘度计测量的影响。通过选择合适的极板尺寸，如频率等，找到了粘度计小型化的可能性，并将其应用于欧共体高温粘度测量项目中的标准参考物质（SRM）的粘度测量。用上述粘度计测得的固体火箭发动机的粘度在SY ±范围内与其它实验室报道的结果一致。（）25%，这是项目开始时设定的目标。除本实验室外，其他实验室均采用转筒法。总之，本研究成功地研制了一种高性能的板式粘度计。少
