The refractive indices at 12 wave lengths in the visible region were measured with the minimumdeviationmethod, showing that KABO is a negative uniaxial optical crystal with moderate birefringence.
Analyses prove that this method is superior to conventional controlling methods in minimum voltage deviation and operating frequencies to achieve multi-object optimum.
分析证明，这种方法优于常规的控制方法，有最小的电压偏差和调节次数，达到多目标优化。
