On the basis of analyzing detailedly the correlative conclusions of the extreme value problem of two variable Function , this paper extends the essential condition and sufficient condition to multi-variable function by using the Taylor Formula 、Quadratic Form 、Hesse Matrix and so on,and gives a method to judge the extreme value of point whose vice-derivative doesn't exist by utilizing Lagranges theorem ,so that compensates for the blank above ,which turns idea that solve the extreme value of multi-variable function problem one by one into realities.
摘要本文在对二元函数极值问题的相关结论进行分析的基础上,用泰勒公式、二次型、海赛矩阵作为工具,将二元函数极值的必要条件和充分条件推广到多元函数的情形,而且还利用拉格朗日中值定理找到了一个判别不可导点处极值的方法,从而弥补了多元函数不可导点处极值无法判断的空缺。因而,使得用穷举判断的方法来解决多元函数的极值问题这一思路成为现实。

Given a mesh, we first solve a Poisson equation to construct a scalar field and use it to generate some critical points. The cutting paths between the critical points and the boundaries are solved in the Poisson scalar field using the deepest descent method. For meshes with nonzero-genus, we construct a Harmonic scalar field, and connect the saddle points with the boundaries based on the Morse theory.

In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.

By using two different three-dimensional source distri- bution techniques, three-dimensional translating-pulsating source (3DT) and three-dimensional pulsating source (3DP), numerical investigations have been carried out for a high speed monohull ship (RD-200) advancing in oblique waves. The numerical results are compared with experimental values obtained from wave load tests carried out at the SSPA. These extensive test results cover different wave directions at a wide range of wave frequencies.

Tennis transformed her from a tall (5-foot-10, though my guess is she's at least an inch taller) giggly, seemingly harmless teenager, and later an elegant woman (hence her new gig on Dancing with the Stars ), into a feisty competitor who looked, frankly, like a pipsqueak compared to Graf (who is, by the way, an inch shorter that Seles).

Rickman has a way of effortlessly stealing any film he's in, but Grant, as the director of a seedy Liverpool theater company, and newcomer Georgina Cates, as starstruck teenager Stella Bradshaw, keep things in balance in An Awfully Big Adventure.
Rickman可以毫不费力地把任何他参与的影片变成他的影片,不过大冒险里有格兰特和新人Georgina Cates可以少许平衡这点。格兰特的角色是利物浦一个破败地方剧团里的导演,Cates扮演一个做着明星梦的少女Stella Bradshaw。
