2. Method: The body temperatures in the 100 emergency patients were measured by the dynamic distant thermometer and mercury thermometer. The reading data were analyzed statistically.

3. Objective: To determine whether there is any difference between the temperature reading measured by the dynamic distant thermometer and mercury thermometer.

4. Electronic thermometer readings is intuitive, easy to carry, compact novel, difficult to damage, more easy to keep than the average mercury thermometer.

5. Measuring body temperature is the primary means to prevent and control influenza, while the traditional mercury thermometer and infrared thermometer are so inconvenient in operation.

6. Besides, what people should pay attention to is that used battery, the light tube of daylight lamp, mercury thermometer, paint pot and medicine are all toxic wastes, which need special disposal.
