查询词典 present simple

A simple polynomial approach for A Class of nonlinear system modeling is presented. By this, the input-output data are firstly changed into [0, 1] by using topological homeomorphism conversion; then an initial polynomial model is selected. The parameters of polynomial model are estimated by using recursion least squares method. A final polynomial model is obtained by repeatedly estimating parameter and eliminating redundant terms.

In the homogeneous model, the function of tendons is assumed to be uniform in some approximated way in order to form an equivalent homogeneous material within concrete. The formulation of the homogeneous model is same with that of general FEM for common continuum, let alone the elastic matrix being resultant of that of tendon and concrete. The computation is simple, but the approximate assumption makes this method cannot be generalized, because it only represents the constitution and function of tendons in such a rough way, that the numerical results are inaccurate. In the combined model, the function of tendon is considered by the stiffness matrix with rod element, then add it into the stiffness matrix of concrete by a rational way.

均匀类单元是设想将钢筋均匀弥散于整个单元中，使其成为一种连续均匀材料单元，这种单元的与一般有限元的单元刚度矩阵推导过程一样，只不过其弹性矩阵由混凝土和钢筋两部迭加而成的，此类单元刚阵计算简明而又不会扩大计算规模，但均匀弥散只是为计算简单而作一种假想，不贴近单元构造实际，也不符合实际作用效果。

就某个方面来看，我们的方法可被视为将homography矩阵的运算，拆解成两个简单的校正过程，因此可以减少多台摄影机校正的运算量。

To time;Appear the phenomenon that more than ten a students carry out homology operation in the campus net Central Standing Committee, so consider the control that erupt the information;Student the exploitation network pretends the industry, the teacher wants to be at home to stir the number interview school network, the student status management information delivers on the net, so also want the safety that consider the network, preventing the black a breakage network, student copy homework;Campus net again is tool that teacher to face to the different knowledge level of structure, student with transact the personnel, it help us betterly exaltation teaching level, transact the efficiency with study the interest, so the application should be simple with the management easy line, interface amity, not proper too the profession turns.

校园网的建设主要是为了教学应用，而多媒体辅助教学和多媒体教室是教学应用的核心，在网络建设时应考虑多媒体信息的特点，如信息量大，对时间延迟敏感等；在校园网中常会出现几十个学生执行相同操作的现象，所以要考虑并发信息的控制；学生利用网络做作业，教师要在家拨号访问学校网络，学籍管理信息在网上传输，所以也要考虑网络的安全性，防止黑客破坏网络，学生抄袭作业；校园网又是面向不同知识层次的教师、学生和办公人员的工具，它帮助我们更好地提高教学水平、办公效率和学习兴趣，所以应用和管理应简便易行，界面友好，不宜太专业化。
