The lesioned group shows sluggish response, getting into the security area over delayed time. All these points indicate that the animal models of abatment of conditioned avoidance response have been well-established. 损毁组动物术后反应迟钝,超过延迟通电时间进入安全区,表明条件性回避反应消退,动物模型已成功地建立。
The authors explore the law of effect of temperature, humidity, grain-size and surface properties of productive dust on its specific resistance, thus providing the basis for improving the design of electric dust collector and dust abatment. 探索生产性粉尘的温度、湿度、粒径大小、表面性质对粉尘比电阻影响的规律,为改进电收尘器的性能及微粒控制提供数据。
The noise propagation ways and noise abatment measures by the floor in passenger cars are described. 介绍了客车地板传播噪声的途径和衰减噪声的措施。
