Using LaGrange theorem on base of analyzing the elastic prop model tension system of band saw machine, the dynamics model of elastic prop tension system of band saw machine has been established and converted to mathematics model applying the modern control theory.

本文以MJ317型木工杠杆压砣张紧系统的带锯机改造成弹性挺杆张紧系统的带锯机为研究对象，通过对带锯机弹性挺杆式张紧系统的弹性动力学分析，运用拉格朗日定理建立了张紧系统的动力学模型，并应用现代控制理论将模型转换成数学模型。

Things often come in pairs. It's said that the translator of 'the New Testament' James Mophead had 3 desks in his study room too. Manuscript of the being translated Bible on the 1st desk, manuscript of an article on the 2nd desk, a half-finished whodunit was put on the 3rd desk.

无独有偶。据说，《新约圣经》的翻译者詹姆斯·莫法特的书房里也有3张桌子：第一张摆着他正在翻译的《圣经》译稿；第二张摆的是他的一篇论文的原稿；在第三张桌子上是他正在写的一篇侦探小说。

The user can be in Beijing not only east store with 2, 999 yuan exceed low case to be bought at present industry La Guang writes the LG GGW-H20L La Guang with the rapiddest rate to cut collection engine, in the meantime, still can obtain freely give 2 pieces of only film magazine to install La Guang of power treasure 25GB BD-R to engrave collection plate, and buy a machine while the user that hopes to have more blue photoetching to record dish, OK still special offer 89 yuan / piece the price (cost price 168 yuan / piece), buy most La Guang of BD-R of 5 pieces of power treasure engraves collection plate (offer this bargain price to the user that buys a machine only) favourable activity.

Firstly properties of the HJ SDF are revealed, and some useful conclusions are obtained. Then by the HJ SDF's properties and the two fund separation theorem, the mean-variance spanning is investigated and the spanning condition is gotten. It is proved by the mathematical method that the spanning condition gotten from HJ SDF is equivalent to the spanning condition gotten from the other methods.

首先研究了HJ随机折现因子的性质，得到了一些有意义的结论；然后结合HJ随机折现因子的性质和两基金分离定理，对均值－方差张成进行了研究，得到了相应的张成条件；最后，从数学上证明，基于HJ随机折现因子得到的张成条件与基于其它方法得到的张成条件是等价的。

This method is based on tensor and tensor algebra. To utilize the multidimensional data of the remote sensing image, the vector-based learning machine is generalized to the tensor-based learning machine which accepts tensors as input, then the convex optimization theory and the alternating projection procedure are used to get the solution of the TLM.

该方法基于张量数据模型和张量代数运算，针对遥感影像数据多维或高维的特点，将基于向量的监督法学习机扩展为基于张量的监督法学习机，然后利用凸函数最优化理论和交互投影迭代法求得张量学习机的最优解。

Two above methods are generalized to tensor product Bézier surfaces and triangular Bézier surfaces, we give two approaches of degree reduction for tensor product Bézier surfaces, each of which reduces a given degree n×m tensor product Bézier surface to a n〓×m〓 one, and two methods of degree reduction for triangular Bézier surfaces, which reduce a given degree n triangular Bézier surface to a degree m one. The explicit formulas of control points for reduced tensor product and triangular Bézier surfaces are obtained respectively.

张量积Bézier曲面的两种降阶方法均可把n×m阶张量积Bézier曲面一次降阶为n〓×m〓阶张量积Bézier曲面；三角Bézier曲面的两种降阶方法均可把n阶三角Bézier曲面一次降阶为m阶三角Bézier曲面，并给出降阶张量积Bézier曲面和降阶三角Bézier曲面控制顶点的显示表示式。

"That one,"Thelma informed me when she saw me turning to the second photo, of a sextry-year-old handsome but stolid woman,"was taken about eight years ago. As you see"--she ran her fingers through her uncombed hair--"I no longer tend to my appearance."

这张，当我看第二张照片的时候希尔玛向我介绍，是一张六十岁优雅但是麻木的女人，这张是八年前照的，如你所见，她用指头梳理着蓬乱的头发，我不再演出乐。
