多元线性回归模型分析显示：血清tc水平与累积噪声剂量呈正相关，与高温级别呈负相关。

The multiple liner regression model indicated that serum TC level was significantly associated with accumulative noise dose, but negative associate with scale of hot environment.

此模型由一“破坏指标”表示，它是最大变形和累积能量耗损两个参数的非线性函数，其统计特性服从威布尔分布。

This model is represented in terms of a "damage index" which is a nonlinear function of maximum deformation and accumulated energy dissipation, and follows Weibull distribution.

以不同应力水平下的破坏率相等进行损伤等效转换出发，建立了新的非线性累积损伤模型。

A new non-linear accumulate damage model was derived from the concept of equal failure probabilities under different stress levels.
