摘　　要：农业机械在长期的农业生产中,不可避免地存在磨损与故障,所以对于农业机械的价值评估是很有必要的。在进行设备评估时,仅通过观察法不能准确地评估设备价值。文章通过Paris公式研究设备表面裂纹的扩展规律,准确计算出设备的剩余寿命,进一步得出设备的实体性贬值,能够准确评估设备价值。In the long-term agricultural production,there are inevitably wear and failure of agricultural machinery,so it is necessary to evaluate the value of agricultural machinery.In the process of equipment evaluation,appraisers can not accurately evaluate the value of equipment only through observation.The Paris formula is used to study the propagation law of the surface crack of the equipment,accurately calculate the remaining life of the equipment,and further get the entity depreciation of the equipment,which can accurately evaluate the value of the equipment.
