resistance variation的用法和样例：
例句
- For example, many transducers have variable resistance which must be converted to a voltage by a special circuit.
举例来说，许多传感器具有电阻变化，这必须由一专门电路转换成电压。 - Unlike a thermal sensor, a superconducting pair-breaking detector cannot rely on a change of electrical resistance to signal the absorption of a photon.
超导体配对瓦解型探测器和感热型探测器不同，它不是透过电阻变化来得知吸收到的光子。
