请问大家下面这段代码中setnamed命令中的几个分别代表什么意思啊？脚本运行的时候发现半径为0.25μm时可以正常运行，但为0.75μm的时候出现一个错误： {v~&.|  
Warning: in run: there was no simulation data. The simulation failed to run. J;'?(xO3\

代码如下： _.wLQL~y  
radius = 1e-6*[0.25,0.75]; O/l|\n  
for (i=1:length(radius)) { js7J#b7  
    setnamed("::model","radius",radius(i)); lty`7(\

    Ex = E.Ex; Fi(_A
