示数“不准”温度计其刻度是均匀的、温度变化和示数变化对应成比例或温度变化与对应刻度线长度变化成正比.所谓“不准”指的是所测值与对应的实际值不符,或每一格表示的实际温度与准确温度计每一格表示的温度不同.由于温度变化和示数变化对应成比例,因此只要巧用数学知识就可复原准确或者说解出准确值.“不准”确温度计上总有一个特殊点,这点所测值与实际温度相同,若将这唯一准确点的温度用t0表示,则当实际温度小于t0时,温度计显示的温度大于实际温度;当实际温度大于t0,温度计显示的温度小于实际温度.
Indicators “not allowed ” thermometer its scale is uniform, the temperature changes and the number of changes in the display corresponding to proportional or temperature changes and the corresponding scale line length is proportional to the change. The so-called “not allowed ” refers to the measured value and Corresponding to the actual value does not match, or each cell that the actual temperature and accurate thermometer each cell that the temperature is different due to changes in temperature and the corresponding change in the number of display, so long as clever use of mathematical knowledge can be restored accurately or solved Accurate value. “Not allowed ” There is always a special point on the thermometer, the measured value and the actual temperature is the same, if the temperature of the only accurate point with t0 said, when the actual temperature is less than t0, the thermometer shows The temperature is greater than the actual temperature; when the actual temperature is greater than t0, the temperature displayed by the thermometer is less than the actual temperature.
