库车地区砂岩储层以高压低孔隙度低渗透率为显著特征，且储层结构复杂，给储层测井评价带来很大困难。

In Kuche area, the sandstone reservoir is characterized by low porosity, low permeability and high pressure, and pore texture is complex, so, it is very difficult for reservoir log evaluation.

小阱宽的量子阱虽然光学限制因子和载流子注入比例都较小，但由于其价带耦合小于宽量子阱，从而具有高的模式增益，说明量子阱的能带结构对其光学特性有决定性的作用。

Although small QW has smaller optical confinement factor and smaller ratio of carriers injected into QW, it can provide higher mode gain because of its smaller mixing between valence bands.
