Photonic quantum-well structures can be constructed by stacking 3 photonic crystals with the same photonic band gap and different defect modes. On condition that the defect mode of the PC in the well region is located into nontransmission frequency ranges of the PCs in the barrier regions, the confined photonic state appears and can completely transmit through the structure by tunneling. However, its transmission will be strongly prohibited due to vanishing of the photonic QW induced by shifting the defect mode frequency of either of the PCs in the surrounded regions to that of the middle PC.

把三块各带有一个缺陷的光子晶体结合起来，如果中央晶体的缺陷模处在两侧晶体的禁带中，缺陷模内的光波会受到两侧晶体的阻碍并被局域在中央晶体内，形成量子阱结构；若一侧晶体的缺陷模被移动到中央晶体缺陷模处，则只有一侧晶体阻碍在中央晶体缺陷模内传播的光波，量子阱效应完全消失，光的传输受到最大程度的阻碍。

In a fluid moving nonuniformly, however, the phonons' velocity is altered and their wavelength can become stretched, just like photons in a curved spacetime.

然而，在流动不均匀的流体中，声子的速度会改变，而且它们的波长也会拉长，正如同弯曲空间中的光子一般。

We studied the jets photoproduction and it's application in testing the perturbative QCD theory, as well as the relations of jets cross section to the parton distribution in photon and proton. The dependence of jets cross section on scales is also discussed both in LO and in NLO corrections.
