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.
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。

Workers exposed to single noise had a higher TG than that exposed to noise combined with hot environment at the same scale of accumulative noise dose.
同一累积噪声剂量水平，单纯噪声接触组血清甘油三酯（TG）高于高温噪声组。

The experiment was conducted to study the pathologic effect of the accumulative toxicity of azithromycin. The chickens were fed a fixed dose of azithromycin (1/5LD50).
