而当介质的吸收较弱时，正折射材料表面的古斯-汉欣位移才会出现正位移。
When the absorption is weak, the lateral shift for the composites with positive refraction will exhibit a positive displacement.
在非共振点处，对称结构中的反射光束具有与透射光束相同的古斯汉欣位移。
It is also shown that the Goos-Hnchen shift of the reflected light beam is the same as that of the transmitted one in the symmetric structure, when the resonance does not occur.
