不平衡电桥在热敏电阻测温电路中应用十分广泛。
The thermistor unbalanced bridge is widely used in temperature measuring circuits.
温度的变化引起热敏电阻阻值的变化，从而使电桥失去平衡，引起流过微安表的电流发生变化。
A changed temperature lead to the change of value of the thermistor, then the bridge balance broke up, which induced the change of current value to the microammeter.
