I never thought I would categorise the Bushes as modern – they've always seemed to me to be representative of a certain kind of preppy American tradition – and I have always considered the younger generation of royals relatively forward-thinking, what with their tongue-piercing and willingness to hook up with commoners.

我从未想过我会把布什一家归为时髦人物，在我看来，他们向来就是中规中矩的美国人的代表。我总以为英国皇室的年轻一代思想相对前卫，言辞犀利，愿与平民结交。

In this paper, we use FEM software ANSYS to simulate. Using FEM to evaluate the strength of pressure hull, the FEM model of outer covering and stiffeners can use shell element to establish, but it may waste much computing time to calculate. Therefore, in this paper, we can evaluate more easier by making use of the idea of effective-width, and considering the stiffener/plating combined moment of inertia.

本文采用有限元素分析软体ANSYS进行求解，在有限元素分析的模拟上，外壳与环肋均可用壳元素建立一实体模型来分析，但是在模型的建立上过於复杂，在解析上也需要更多的时间来计算，因此本文采用有效幅度的观念，考虑环肋与壳板间之组合惯性矩，将环肋部分取梁元素来模拟，如此一来可简化建立模型的困难度，且大大的缩短分析的时间。

Aimed at low-SNR infrared images, this paper analyzed principle and computational method of Zernike moments, proved rotation invariant property, proposed a method for low-SNR infrared target detection based on Zernike moments,and compared target recognition effect among template matching, Hu moments and Zernike moments via experiment.
