But the differences of material? Construction and work condition of actuator lead to difficulty of setting up a standard mathematic model to precisely formulate the dynamic non-linearity character.

但由于驱动器的材料、结构和工作条件各异，所以关于动态非线性的定量描述难以建立一个统一的数学模型。

The conclusive analysis of the data leads out the following rule: the linearity between NOconcentration and photon counting rate exists when the system is in good condition.

通过对数据的分析总结，得出如下规律：系统在一个比较稳定的状态下，NO浓度与光子计数率成线性关系。
