one-time fuse 一次性的保险丝
Solid ink machines need about one-third as many parts as laser printers, which require various mechanisms to fuse toner onto paper that must be replaced over time, adding materials and services costs.
固墨打印机所需零部件仅为激光打印机的三分之一，激光打印机需要各种不同的原理来将炭粉融化到纸上，炭粉久了以后必须进行更换，增加了材料与服务成本。
The AD5172/ AD5173 are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers1 that employ fuse link technology to achieve memory retention of resistance settings.
AD5172和AD5173是一款双通道、256抽头、一次性可编程（OTP）数字电位器，它采用熔丝链技术实现永久性程序设置。
