玻璃釉电位器的机械寿命也称磨损寿命，常用机械耐久性表示。寿命直接的相关的就是使用度，和使用强度。到达一定的磨损度，机器自然就会出现许多其他的故障。

    Glass glaze potentiometer mechanical life also wear life, common mechanicaldurability said. Life is directly related degrees, and the intensity of use. Toa certain degree of wear, the machine will appear naturally in many otherfault.
   其结构和材料也有一部份的关系，机械寿命与玻璃釉电位器的种类、结构、材料及制作工艺有关，差异相当大。

    Its structure and material, but also a part of the relationship, mechanicallife and glass glaze potentiometer type, structure, material and manufacturingtechnology, considerable differences.
