| 摘 要： | 放射线同位素~(85)Kr 使用安全,获取方便。作者研究用此试验测定10~(-5)g 以下的微磨损量。从实验和理论上分析、比较了放射性衰变量和磨损量的定度关系曲线。提出两类曲线仅与氪化时间、吸收系数与扩散系数有关。氪化时间可以控制。吸收系数与材料类型有关。扩散系数与材料状态及表面处理有关。若通过大量实验,求得上述两者的关系,氪化法是可以测定微磨损量的。 |

| Abstract: | The radio-isotope~(85)Kr can be easily obtained and safely used.It can be usedto determine the micro wearing loss below 10~(-5)g.Having studied both theoreticallyand experimentally the calibrated relative curves of decay volume and wearing losswe found that the curves are only related to kryptonation time,absorption coeffi-cient and diffusion coefficient.In addition,the kryptonation time can be controlled,the absorption coefficient is related to the kind of material,and the diffusioncoefficient to its state and surface treatment.If we can find the relationship,between the diffusion coefficient and the state of material by numerous experiments,we can determine the micro wering loss by kryptonation. |
