In this paper,the author discusses the multi-layer solution with two special limits in boundary layer of the singularly perturly boundary value problem and obtains uniformly valid zero order asymptotic expansion by using the matching asymptotic expanding method.

First, in the construction asymptotic expansions, it does not need to perturbations of the structure so special series of assumptions, or the need for a asymptotic matching, but generated its own approaches applicable to the asymptotic series.

首先，在构造渐近展式时，它不需要对摄动序列的结构做特别的假设，也不需要使用渐近匹配，而是生成自己的适用于问题的渐近序列。

Firstly, Receding horizon H〓 control based on state feedback with terminal constraints is proposed for systems with disturbance inputs and parameter perturbations. Linear Fractional Transformation and some existed results on Receding horizon H〓 control for systems without perturbations are introduced.

首先针对同时存在外界输入扰动和自身参数摄动的不确定线性时变系统，利用线性分式变换和现有的一些无摄动系统滚动时域H〓控制的结果，得到了基于状态反馈的终端约束滚动时域H〓控制器的设计方法，并给出了控制律存在和使闭环系统渐近稳定的充分条件。

The asymptotic solutions of non-uniform conical shells under arbitrary boundary conditions are determined by double-parameter perturbation technique and transfer function method.

利用摄动方法，将微分方程进行双参量摄动，采用传递函数法对所得到的摄动方程进行求解，得到了变厚度圆锥壳在任意边界条件下的渐近传递函数解。

I used it in reportage style picture taking situations and could get very interesting pictures at close range.

我用这镜头以报道方式拍摄了一些场景，并在近摄中得到了很有趣的图片。

You can also define a scale factor from two to 16x for an extreme close-up.

首先，分析J2摄动对编队卫星相对轨道要素的影响，即J2摄动使相对升交点赤经、近地点辐角和平近点角产生长期漂移。

For those who drift negative, there's a healing room of crystal bowl sound therapy, shamanic pick-me-ups and Egyptian healing rods.

对于那些谁漂移消极，有一个愈合室晶体碗健全治疗，萨满提神近摄和埃及愈合棒。

Forcastle Deck: Shows a close up of the forcastle deck, the camera is focused in on the bitts, you can see the figure heads on them.

As you can see, there areclose ups, photos of him at conferences,caricatures, and group photos.

你可以看到，有近摄，照片的，他在各种会议，漫画，组照片。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
