一、常用温度计的玻璃管的内径为什么做得很细而且均匀？常用的温度计是根据液体热胀冷绩的性质制成的．它的液泡容积较大而内径做得很细，其目的是：当被测物体温度发生较小的变化的，玻璃管内液面上升或下降较大的幅度，从而能明显读出温度变化的示数．同时为了使温度计刻度 First, why do the inner diameter of the glass tube of the common thermometer be very fine and even? Commonly used thermometers are based on the properties of liquid thermal expansion. Its volume is large and its internal diameter is very thin. Its purpose is: when the temperature of the measured object changes slightly, the liquid level in the glass tube rises or falls by a greater extent, so that the temperature change can be clearly read out. number. At the same time in order to make thermometer scale
