The ground-state binding energy of an exciton confined in quantum wires and quantum wells in the presence of a uniform electric field has been calculated under the effective-mass approximation using variational approach.

本文采用变分法研究了外加电场下无限深方形量子线中重空穴激子的束缚能，我们用平面波展开的方法求解在电场作用下无限深方形量子线中电子和空穴的基态能和基态波函数及低激发态的能量和波函数，并用所得到的波函数进一步计算激子的基态及低激发态的束缚能，最后计算了激子的Stark能移。

Both the two parts are uniformly analyzed from the viewpoint of energy under the assumptions of small deflection and uniform applied magnetic field.

在小变形和均匀外加磁场假设下，这两部分统一地从能量观点作出了分析。

The influence of the electric field on the properties of the bound magnetopolaron in an infinite-depth GaAs semiconductor quantum well is investigated using the linear-combination operator and the unitary transformation method. The relationships between the polaron's ground state energy and the Coulomb bound potential, electric field, magnetic field, and well-width are derived and discussed.

研究了在外加电场作用下无限深GaAs半导体量子阱中束缚磁极化子的性质，采用线性组合算符及幺正变换方法导出了量子阱中弱耦合束缚磁极化子的基态能量与阱宽、电场强度、磁感应强度、库仑束缚势的变化关系，同时讨论了振动频率和库仑束缚势、外场之间的变化关系。

What kept us watching through six seasons and one summer blockbuster , was their willingness to go to dark, unlikable places (i.e., Carrie cheats on Aidan and Big on his new wife, Natasha; Big leaves Carrie at the altar!).

而我们之所以能坚持看完六季剧集外加一部电影，是因为其中一些黑暗又真实生活里不太可能发生的桥段（比如Carrie背着Aidan和Big偷情，Big背着未婚妻Natasha和Carrie开房间，还有Big把Carrie一个人扔在教堂里！

More accustomed to wearing, unlined garment wear, inside or compassionate, plus jackets.

如果你习惯多穿，可穿单衣，或者里面体恤，外加外套。

The first love is a little unwieldiness added with a lot of curiosity.

初恋就是一点点笨拙外加许许多多好奇。

Because the additional reference signal is not necessary, the delayed time is not related to the period of UPO and should not be the integral multiple of the period of UPO, so the presented method is simple and easy to apply.

由于不需要外加参考信号，延迟时间与UPO的周期无关，不必是UPO周期的整数倍，所以该方法简单易行。转载于中国论文联盟 http：//www.lwlm.com

我们为上层楼厅包厢的票另外加付了钱。

The upshift of valence band edge and the downshift of conduction band edge under tensile strain are responsible for that.

这是因为外加伸展应力使得矽的价电带往上移动以及导电带向下移动造成。

Its features : Filter samples with no additional buffer vacuum bottle.

其特点：过滤样品时不需要外加真空泵与缓冲瓶。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
