对于正则曲线的情形，我们发现了两个用于求解p-弹性曲线的结构方程的Killing向量场并用积分将p-弹性曲线在一个柱面坐标系中表示出来，而对仿射星形曲线的情形，我们用积分方法解出了欧拉-拉格朗日方程，利用Killing向量场及线性李代数s1(2，R)、s1(3，R)和s1(4，R)的分类将高阶结构方程降为一阶线性方程，因此我们用积分完全解出了中心仿射p-弹性曲线。

At the same time, we studied the influence of quantum interference on the squeezing spectrum of the resonance fluorescence emitted from a V-type three-level atom and a -type four-level atom which are driven by coherent fields. We showed that quantum interference can greatly enhance squeezing in the components of phase quadratures at atomic frequency and change the squeezing spectrum .

同时，我们还研究了量子干涉对V型三能级和型四能级原子共振荧光压缩谱的影响，结果表明，量子干涉可显著加强原子跃迁频率分量的相位压缩效应和改变压缩谱的形状。

Since RKPM is a kind of Galerkin meshfree methods, in this thesis, penaltyfunction method is employed to enforce the essential boundary conditions,trapezoidal rule is used for the approximation of displacement field function, Gaussand Hammer quadratures are applied for the numerical integration of systemequation,self-adapting method is applied for confirming the support of the pointinterpolated.

针对 RKPM 是一种伽辽金型的无网格方法，本论文采用罚函数法引入位移边界条件，用梯形积分法则近似位移场函数，对系统方程进行积分时分别使用了 Gauss 积分和 Hammer 积分，采用自适应的方法确定计算点的定义域。

Integrated by quadratures.

这就使得孤子方程容易地被积出。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
