Lots of investigators' interests, in the problem of an electron bound to a hydrogenic impurity and interacting with the longitudinal optical phonon field of an ionic crystal or a polar semiconductor, have been main- tained over years.

采用线性组合算符和么正变换方法研究强弱耦合情形下，库仑场中束缚光学极化子的基态能量、振动频率和平均声子数与温度的关系。

The ground-state energy and the average number of virtual phonons around the electron of a hydrogenic impurity confined in a parabolic quantum dot are calculated using the squeezed-state variational approach,which is based on two successive canonical transformations and uses a displaced-oscillator type unitary transformation to deal with the bilinear terms,which are usually neglected.

The consumers take themselves in kinds of cognitive contexts of the consumable when they start to incept the information codes about the consumable, and in this process, the consumer's cognitive structure towards the consumable is being formed.

消费者对商品的认知开始于消费者身边各种关于商品的认知情境，不断地接受到关于该商品的信息符码，并对其进行解码。在这一过程中，形成了消费者对该商品的认知结构，解码成功的信息就成为了认知结构中的知识基础。

The radio channel is time-variant, frequency-selective and noisy, so the received OFDM signals are corrupted by intercarrier interference.

但是由于无线信道的多径性和时变性，造成了接收端 OFDM 符号子载波间的干扰，为了能够准确地解调 OFDM 信号，就必须对接收到的信号进行信道估计。

For orthogonal frequency division multiplexing systems in high-mobility environment, channel variations within one OFDM symbol will introduce intercarrier interference, thus lowering the system performance.

对於应用於高移动通讯环境之正交分频多工(Orthogonal Frequency Division Multiplexing， OFDM)系统，每一个OFDM符元期间的通道时变导致载波间干扰(Inter-carrier Interference， ICI)发生，使得系统效能降低。

In conclusion, the load of ischial tuberosities could be effectively mitigated in sitting position when the adjustable soothing chair was used; the adjustable mechanism could make the shape of the back-support match more with the curvature of lumbar spine, so that the touching face of waist toward the chair was increased and then the load of back muscle was decreased.

因此使用可调式抒压座椅时，能在坐姿时有效地减少坐骨粗隆所承受的负荷，其中可调式调整机构能使背垫的形状更符贴於腰椎的曲线以增加腰部接触面积进而减少背部肌肉的负担，并且尽量维持腰椎前凸的曲线，减少造成下背痛的发生率。

But under the tunic of each of the dead they found amulets sacred to the idols of Jamnia, which the law forbids the Jews to wear. So it was clear to all that this was why these men had been slain.

当时在每个死者的内衣下，发现都有雅木尼雅偶像的符录，这原是法律禁止佩带的；众人便都明白这正是他们阵亡的原因。
