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： y
pv~F  
Warning: in run: there was no simulation data. The simulation failed to run. c3&;Y0SD  
Error:  Can not find result 'E' in the result provider 'field'

代码如下： Re{vO&.  
radius = 1e-6*[0.25,0.75]; `r:n[N=Y&  
for (i=1:length(radius)) { CD'.bFO^+T  
    setnamed("::model","radius",radius(i)); 7Rf${Wv0  
    run; ^b]h4z$  
    E = getresult("field","E"); c|%.
