Using improved euler method to solve the grey system model was simple and rapid. The predicted value accorded basically with the surveying value.
采用改进的欧拉算法求解灰色系统模型简单快捷，预测结果与实测值基本符合。
Meanwhile, monitoring parameters will be predicted by a GM model of Grey Theory, and engine health condition will be analysed early.
同时使用灰色理论中GM预测模型对发动机的监测参数进行预测，从而及早分析出发动机所处工况。
