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： Ncs4<"{$  
Warning: in run: there was no simulation data. The simulation failed to run. ;HD 4~3  
Error:  Can not find result 'E' in the result provider 'field'

代码如下： >e5q2U   
radius = 1e-6*[0.25,0.75]; .If"'hMY  
for (i=1:length(radius)) { $cp16  
    setnamed("::model","radius",radius(i)); .x\/XlM  
    run; %Q>~7P  
    E = getresult("field","E"); "^e}C@  
    x = E.x; {7j6$.7J$&
