(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)为了提高颗粒计数器测量微小颗粒的性能，我们对所研制的颗粒传感器进行了改进。此外，我们完成了一个转移矩阵法，从颗粒传感器获得的结果和每个尺寸的颗粒的脉冲高概率的数学计算粒度分布。(2)利用光学显微镜、CCD摄像机和频闪仪组成了一套在线图像分析系统，用于分析润滑油中磨粒的形状。验证了该观测系统的可靠性和可用性。(3)利用自行研制的磨损颗粒在线观测系统，对轴承金属（LBC3）磨损试验所用润滑油中的磨损颗粒进行了在线分析。发现磨粒的长径比和粗糙度随摩擦系数和比磨损率的变化而变化。(4)在轴承金属（WJ2）的磨损试验中，使用颗粒计数器实时监测润滑油中磨损颗粒的尺寸分布和数量密度。磨粒分布随磨损过程或接触载荷的变化与磨损量的变化相对应，因此磨粒分析结果与磨损模式之间存在相关性，从而使我们开发的基于磨粒计数器的润滑磨损监测系统能够实时预测润滑磨损的严重损伤。
