(1) In order to advance the performance of small particle measurement by means of a particle counter, we improved our developed particle sensor. In addition, we completed a transfer matrix method to calculate mathematically particle size distribution from the results obtained by the particle sensor and the pulse hight probability of each size particle.(2) An on-line image analyzing system using an optical microscope, a CCD camera and a strobo scope was constructed in order to analyze the shape of wear particles in lubricanting oil. The reliability and availability of this observation system were comfirmed.(3) The wear particles in the lubricating oil which was used in the wear tests of bearing metal (LBC3) were analyzed at on-line using our observation system. it is found that the aspect ratio and the ruggedness of wear particles vary with the friction coefficient and the specific wear rate.(4) During the wear tests of bearing metal (WJ2), the size distribution and number density of wear particles in lubricating oil were monitored at real-time using our particle counter. The variation of the distributions of the wear particles with wear process or contact load corresponded to that of wear loss, consequently there were correlations between the particle analysis and wear modes.From these results, our developed monitoring system using the particle counter is able to predict severe damage of lubricated wear at real-time.

（1）为了通过粒子计数器提高小粒子测量的性能，我们改善了开发的粒子传感器。此外，我们从粒子传感器获得的结果和每个尺寸粒子的脉冲高概率中完成了传输矩阵方法，以计算数学上的粒度分布。（2）使用光学显微镜，CCD摄像头和Strobo范围进行了在线图像分析系统，以构建型号的颗粒形状，以分析磨损颗粒的形状。 （3）使用我们的观察系统在线分析了该观察系统的可靠性和可用性。发现纵横比和磨损颗粒的坚固性随摩擦系数和特定的磨损速率而变化。（4）在轴承金属（WJ2）的磨损测试中，使用我们的粒子计数器实时监控润滑油中润滑油中磨损颗粒的尺寸分布和磨损颗粒的数量密度。磨损过程中磨损颗粒的分布的变化与磨损损失相对应，因此粒子分析和磨损模式之间存在相关性。从这些结果，我们使用粒子计数器开发的监测系统能够预测实时润滑磨损的严重损害。
