A method of moment features testing components' states is put forward to solve this problem.First the components' barycentric coordinates and second-order centered moments are calculated.Then the inclined angles are obtained,on the basis of which the inclined components can be rectified.

针对这一问题，提出了一种矩特征检测构件状态的方法，该方法首先计算出图像中构件的质心坐标和二阶中心矩，然后求出构件的倾斜角度，根据倾斜角对处于倾斜状态的构件进行校正。

The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

The Guidant-independent Teaching Model of High School Biology sticks to the principle of student-oriented so as to build the classroom atmosphere of democratic, fair, free and open, active the effective teaching interaction and enable students to participate actively in classroom teaching and develop the activeness and independence of students. The Guidant-independent Teaching Model adheres to the rule of students-centered. It proposes teaching-after-self-learning, teaching-follow-self-learning, teaching-promote-self-learning and enables students to learn by themselves at first through reading, self-thinking, questioning, group-discussion and forum.Thus, the independence and imitativeness of students will be achieved.We also lay emphasis on the development of the abilities of self-study and co-operative study so as to get the teaching goal of "learn how to learn" and promote the development of the independence of students.

引导自主式高中生物课堂教学模式坚持以学生为主体，通过营造民主平等、自由开放的课堂教学氛围，实现有效的教学交往和互动，让学生主动参与到课堂教学中来，以发挥学生主体的积极性、主动性；引导自主式高中生物课堂教学模式坚持以学生为中心，主张先学后教、以学定教、以教促学，通过阅读、独立思考、质疑、小组讨论和集中交流等环节让学生自主先学，以充分发挥学生主体的能动性、创造性，培养学生自主学习和合作学习等能力，从而实现学会学习的教学目标和促进学生主体性的发展。

LBIE, based on the local boundary equation, adopts the traditional moving least squares approximation which depends on only the values of the nodes in the domain of the problem or along its boundary. The whole process of integration is carried on over a local domain or its local boundary centered at the node in question. The local boundary equation can be rewritten to represent the values of the unknown function at the point of interest, and the essential boundary conditions can be directly and easily enforced by using the Green formula and the characters of the Dirac function.

它以局部边界积分方程为基础，采用移动最小二乘近似函数，从而只需要分布在问题域内及其边界上的节点的信息值，无需划分单元；整个积分是在以节点为中心的局部域及其边界上实现，所以不需要背景积分网格；借助于格林公式及Dirac函数的性质，将局部边界积分方程转化为所考虑点的未知函数的边界积分表达式，便于直接施加本质边界条件。

The modelview transform is used in the same way as it is in the OpenGL viewing pipeline, to move the viewer to the origin and the projection centered along the negative z axis. In this case, viewer can be thought of a light source, and the near clipping plane of the projection as the location of the texture image, which can be thought of as printed on a transparent film.

模型/视图变换的作用和它在OpenGL 观察管道里的作用是一样的，它将观察者沿-Z方向移动到原点和投影中心，在这种情况下，观察者就好比是是光源，近裁剪平面好比是需要投影的纹理图象的所处的位置，纹理图象可以被看作一个在投影的透明胶片。

Be in from the ground in the atmosphere advection layer of 50 kilometers of 15 ～, centered the ozone gas of on the earth 90%, although its chroma never exceeds 1/100000, all concentration rises to also have a even thinner than sole only, but it assimilated opposite substance effectively harmful, wavelengh is less than the UV-C of sun ultraviolet ray of 295nm, and opposite content hurtless, wavelengh is more than the UV-A of sun ultraviolet ray of 320nm to make them all pass however, opposite content has certain harm, wavelengh is in the UV-B of sun ultraviolet ray of 295 ～ 320nm also is absorbed for the most part.

在离地面15～50公里的大气平流层中，集中了地球上90%的臭氧气体，虽然其浓度从未超过十万分之一，全部集中起来也只有比鞋底还要薄的一层，但它却有效地吸收了对生物有害的，波长小于295nm 的太阳紫外线 UV-C，而对生物无害的，波长大于320nm 的太阳紫外线 UV-A 却让它们全部通过，对生物有一定危害，波长在295～320nm 的太阳紫外线 UV-B 大部分也被吸收。
