A special configuration reducing stress distortion and a method for integralcoupling of multi-lenses connecting in the processing of optical assembly and rectification are given in detail.
The results show that the effective exchange integral values are less than zero under different conformations, so the radicals display the anti-ferromagnetic coupling.
结果表明，不同构象下各体系有效交换积分值都小于零，自由基间表现为反铁磁性耦合。
