Methods Animal models were established by ovariectomy and exodontia on left partial Maxillary.

方法通过去除SD大鼠双侧卵巢，拔除单侧上颌磨牙，建立骨质疏松的剩余牙槽骨动物模型，并在此基础上通过免疫组化方法观察、分析切除卵巢及单独和联合运用生长激素、雌激素对去势大鼠剩余牙槽骨内胰岛素样生长因子分布和表达的影响。

Based on the general Nernst equation, thermodynamics model of the submonolayer equilibrium potential was set up.

基于普通的能斯特方程，建立了单原子层平衡电势的热力学模型。

The n-type gate modulation could be explained by the bending effect of valence band in the Schottky-barrier junction. The photoconductive diode and optical switch behavior was demonstrated for the first time from a C/CNX multi-walled nanotube junction with a Schottky barrier. Theconductivity of nanotube can be reversibly changed by 3 to 4 orders of magnitude when the 5 mW cm2 white lights was turned on and off.

器件原理是栅极静电场调节碳纳米管和CNx纳米管间的Schottky势垒的高度和宽度，从而影响载流子的传输。8首次利用单根CN万／C纳米管作为半导体材料制备了Schottky光导二极管和光开关。

In this thesis, we mainly discuss the potential symmetries and linearization of the nonlinear evolution equations.

本论文主要研究非线性发展方程组及单方程的势对称以及它们的线性化。

In this paper, an improved sensorless control strategy, which is based on the detection of zero crosspoints of back-EMF, is proposed. In this method, only one feed back signal is needed to sense terminal voltages and no motor neutral line is required. The phase shifter errors in traditional methods are eliminated.

本文同时提出了一种改进的无位置传感器检测方法，这种方法基于反电势过零点检测的基本原理，采用单路位置反馈信号，无须引出电机中性线，硬件结构简单，消除了传统检测方法中由于深度滤波产生的相移和误差。

Lastly,a nonlinear oscillatory system with a single potential well is studied.

在本文的最后，对一类含单阱势的非线性振动系统的安全盆的侵蚀进行了研究。

By adopting its complex variable solutions, the stress solutions of dislocation in bi-material on the whole plane were worked out, integration of which along the crack line would lead to the basic stress solutions in Cartesian and polar coordinates system of an bi-material incline crack.

应用两相材料中点位错在全平面的复势函数解，导出了两相材料中点位错在全平面的应力场解，进而将该解沿裂纹线积分得到倾斜裂纹的直角坐标及极坐标应力场基本解，同时利用该基本解退化出单根界面裂纹的直角坐标及极坐标应力场基本解。

P. P. Raevski〓, and pointed that this polarization at grain boundary between WO〓 monoclinic and triclinic phases causes a modification to Schottky barrier is origin of nonlinear electrical characteristic of tungsten oxide polycrystalline ceramics.

Raevski〓的铁电半导体非线性电输运理论模型的框架内，我们重点考虑了铁电极化对WO〓陶瓷非线性电输运特性的影响，指出由于三斜和单斜晶相的共存，在其晶界处存在的电极化可以对Schottky势垒产生一种修正，是导致出现压敏现象的一个重要因素。

We are not to leave any country or corner of it unsubdued. That slum near our house is before us, not to baffle our endeavors, but to yield to them.

周围广大的人群，正是我们传福音的目标，不要因为他们人多势众而产生无力感，也不要因为自己势孤力单而泄气、裹足不前。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
