群里面的大神帮帮忙，LM324的仿真文件无法打开是什么原因，换了几个都不行。我另外一台电脑可以正常。系统都是WIN10 64.

别的电脑可以的话，那就是系统问题了。或者软件安装问题。

估计模型自己建的吧

*Features:
*Eliminates need for dual supplies
*Large DC voltage gain =          100dB
*High bandwidth =                   1MHz
*Low input offset voltage =          2mV
*Wide supply range =       +-1.5V to +-16V
*
*NOTE: Model is for single device only and simulated
*    supply current is 1/4 of total device current.
*    Output crossover distortion with dual supplies
*    is not modeled.
