q-banding meaning in English

q显带

There were both obvious q - band shifts in the absorption spectrum , while no variations in crystal structure showed in xrd results
实验结果显示酞菁的吸收峰发生了不同程度的移动，而晶体结构并没有明显改变。
The absorption spectrum of these composite materials between 200 - 800nm were measured to determine their q - bands , and they were found having good third nonlinear optical properties perhaps
测试了它们在不同状态下的紫外-可见光谱( 200 800nm ) ，发现它们具有一定的非线性光限幅效应。
Vanadyl phthalocyanine ( vopc ) films prepared by vacuum deposition were annealed under magnetic field . uv - visible absorption results showed that the films annealed under magnetic field showed a q - band red - shift . x - ray diffraction study ( xpj ) ) indicated enhancement in diffraction intensity and shift of peak position
