Because fault symptom space and fault space have complicated non-linear relations, the mathematical model of diagnosis system is difficult to build up.
由于故障征兆和故障类型之间常常存在复杂的非线性关系,使得诊断系统的数学模型很难获取。

As one of the important branches in statistic theory, the non-linear function has a large application in model-identification.
非线性函数逼近作为统计理论的一个重要分支,在模式识别中有着广泛的应用。

Meanwhile, the paper has given its own opinion of that how to settle the non-linearmodel problem.
