During the burning test, check the temperature rise, voltage, current, if find abnormal, need analyze and repair.

老化过程中检测产品温升、电压、电流，发现有异常的，应拿出来分析维修。

The features of EEG abnormal changes were global or focus paroxysmal middle-high or extremely high voltage delta wave or mixed delta theta activity associated with sharp wave discharge, and in hyperventilation with 4-6c/ sec spike and wave complex.

脑电图异常改变以全脑或局灶性阵发性中～高或极高电位的δ波或δ、θ混合活动，伴尖波发放为特征，过度换气中可见每秒4～6次棘慢综合波。

Terminal is a vital part which connects MCCB and power line. Abnormal temperature rise will not only produce hidden trouble in mechanical part, leading to accident in low-voltage power distribution network, but also cause electrical fire in buildings.

接线端子是承担断路器本体与导线连接的重要部件，其温升异常不仅会造成设备的机械连接隐患，使低压配电网络发生事故，同时也会形成电气火灾隐患。

高压直流线路电压异常波动对分接开关控制的影响

With the increase of blood pressure, detectable rate of abnormal ECG such as left ventricular hypertrophy, high voltage of left ventricle, ST-T changes, bundle branch block, old myocardial infarction and premature ventricular arrhythmia was increased remarkably ( P0.01 for all).

高血压者临床心电图异常如左室肥厚、左室高电压、ST-T改变、各类早搏、束支传导阻滞、房室传导阻滞、陈旧性心梗等的检出率显著高于非高血压者（均P0.01）。
