By means of analyzing the noise error, it is proposed to use an algorithm of singular value decomposition total least squares to conduct the interharmonics estimation, namely taking the noise interference at both sides of the matrix equation into account simultaneously and solving the minimum norm problem by least square method under such condition. In the proposed algorithm by means of singular value decomposition of a new augmented matrix and by use of a simple and practical method to determine the number of principal singular value related to signal to noise ratio, the storage calculation of right singular matrix is performed, thus a more accurate frequency estimation of interharmonics can be obtained.

通过分析噪声误差，提出采用奇异值总体最小二乘(singular value decomposition total least squares，SVDTLS)算法进行间谐波频率估计，即同时考虑矩阵方程两边的噪声干扰，采用SVDTLS算法求解该情况下的最小范数解，通过对增广矩阵进行奇异值分解(singular value decomposition，SVD)，采用简单实用的与信噪比相关的主奇异值个数确定方法对分解的右奇异矩阵进行存储计算，得到了较精确的间谐波频率估计结果。

The apparatus regards the laser beam, emanating from the laser device, which can emit the perpendicular laser to the earth, as the measuring norm. The facula on the autodyne, which clings to the guide way during the measuring, is sampled to computer with a CCD camera and an image acquisition card. By computer image proce~sing, the measuring apparatus can identify the displacement of the facula center .By this way it determines the verticality error of the guide way at the measuring position, which can be recorded automatically at the same time.

It is a global convergence method, so it can avoid the drawback of the Newton method.

它的主要思想是将Euler-Lagrange方程中TV-范数做一个足够大的扰动，得到一个能用以观测图像z为初值的牛顿法求解的辅助方程，通过构造同伦方程将辅助方程和Euler-Lagrange方程联系起来。

我想回到轴承，以绝对完美的排列与中心，我有一个坚实的传动轴越走越回到较规范，以变速箱没有任何普遍接头，以补偿任何的任何不完善之处。

Even without mass take-up of e-book devices, digital book content is rapidly gaining ground—to be accessed and read via PCs, laptops, iPhones, Blackberries, Palm Pilots etc. So for trade publishers, ambitious digitisation has become the norm. DK plans to have 2,000 backlist titles digitised by the end of 2008 and parent Penguin has 5,000 e-book titles already available, with another 5,000 scheduled for the end of the year, including all key frontlist titles.

"我们现在不打算放弃我们电子图书销售的权利，"英国 DK 出版公司的 CEO 安德鲁·菲力普斯说，"但是还有很多事情悬而未决，新的应用平台不断诞生，移动电话科技的发展，零售商和电子零售商都在争夺这一市场，在数字出版领域有越来越多的参与机构，同时人们对电子图书市场的觉醒和期望也在增长。"

To determine whether a norm baric hypoxia cause's weight loss, 12 male 5-week old Wistar rats raised at an altitude of 2 260m were continuously exposed to a small hypoxic chamber with 10％ O2, which is equivalent to 5 000m, for 20 days.

为了确定大鼠的体重是否在标准气压缺氧环境下会减轻，本实验将12只5周龄Wistar大鼠移高至海拔2 260 m并使之持续暴露于含10％O2的低氧小低压舱内(相当于在海拔5000m)20日。

The uncertainty is assumed to be unknown continuous function with norm-bounded restriction. The perturbation is sector-bounded.
