The PSE in the curve coordinate systems are solved by the numerical techniques developed efficiently in this paper. A normal transform is introduced, and there are enough much grids in the region between the critical layer and the wall, where the variation of the disturbance is the quickest. The finite-difference of governing equations with fourth-order accuracy in the normal direction is utilized in full regions including points close the wall, and is very important for accurately discreting equations.

对于曲线坐标系下的抛物化稳定性方程，文中发展了求解的高效数值方法：引进法向变换，使得在临界层与壁面之间的扰动量变化最快的区域有更多的法向网格点；导出包含边界邻域在内的完全四阶精度的法向有限差分格式，这对方程精确离散至关重要；采用全局法和局部法相结合的方法及其新的迭代公式，大大加速收敛并得到更精确的特征值。

Again echoing Mr Meshaal, he pins fresh hope on Barack Obama, copiously praising his Cairo speech to the Muslim world in June."In general it was excellent," he says. I do believe he's sincere.

他回应了Mr Meshaal，流露出对Barack Obama抱的一丝希望，大大赞扬了后者6月在开罗对穆斯林世界进行的讲话，他说总体来说非常好，我相信他表现出来的诚意。

"There is only one thing to do," Cornwallis said.

"只有一个办法，我们必须找到另一个信号源，它发出的信号必须大大超过我们飞船上的灾难信号发射站，大到它的信号能被地球接收到。"

At present the camber process system is more advanced in china. We imported servo-drive equipment with digital control system , greatly improved our process precision, can produce multi-curve camber such as cosine curve. The process ability is up to 680mm in diameter and 10m in length.

该系统是目前国内较为先进的胶辊中高加工设备，采用进口数控系统和高精度的伺服驱动设备，使加工精度大大提高，可加工如余弦曲线等多种曲线中高，加工能力为直径680mm，长度10000mm。

The main contribution of this thesis is that we propose a collaborative filtering recommendation algorithm based on double clustering. This approach first respectively clusters resources and users by the users rating on items, then makes a collaborative filtering recommendation based on the clustering result. The new algorithm can shorten on-line recommendation time. Then, we apply the classical formula of cosine correlation to double clustering algorithm, leaving out the standardization operation. In the end, we implement an educational resource recommender system according to the need of the actual project and the result is positive.

本文的主要意义在于，首先运用聚类技术对用户和资源分别进行聚类，然后利用聚类结果进行协同过滤推荐，由于聚类部分离线周期进行，大大缩短了在线的推荐时间；然后将经典的余弦相似性计算公式运用到双重聚类算法中，省去规范化处理操作，减少运算量；最后结合实际的需要，实现一个资源推荐系统。
