本文基于大型通用有限元软件ANSYS和MATLAB,探索三维实体模型下进行PC桥梁结构整体仿真分析的途径,研究其关键理论及专业模块开发技术。重点研究了预应力筋的模拟、预应力效应的等效转换和桥梁截面切片技术。研究成果可广泛应用于PC桥梁的三维仿真领域,具有较大的理论意义和工程实用价值。对写这方面研究很有帮助(Based on large-scale general-purpose finite element software ANSYS and MATLAB, explore the three-dimensional solid model of the bridge structure under the PC way to the overall simulation analysis to study the key theoretical and professional development of technology modules. Focused on the tendons of the simulation, the equivalent effect of prestressed bridge conversion and cross-section slicing. Research results can be widely used in PC bridges the field of three-dimensional simulation with the larger theoretical and practical engineering value. Research in this area to write very helpful)

一个关于matlab的教程，对于初学者来说是非常有用的(A tutorial on matlab for beginners is very useful)

关于matlab fixunknowns函数问题给出我的解答(Give me answers about the issue of the matlab fixunknowns function)

Co-Optimization of Generation Unit Commitment and Transmission Switching With N-1 Reliability

说明：  将数组a[0]~a[size-1] 中重复的字母删除（仅仅保留第一次出现的字母，后续的重复字母均删除）(The array a [0] ~ a [size-1] Remove duplicate letters (just the first time to retain the letters, follow-up letters were removed duplication))

基于windows form的智能拼板程序，含源代码。(a PCB layout tool based on windows form. the source code is included.)

离散数学用matlab实现，包括手实例(about matlab，about sign)

用MATLAB实现带状矩阵A的LU分解，参数为A的主对角线元素组成的列向量(A MATLAB implementation by the LU decomposition of banded matrix, the parameters for the A' s main diagonal elements of the column vector)

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”。例如6=1＋2＋3.编程 　　　 找出1000以内的所有完数。 (If a number is just equal to the sum of its factors, this number is called &quot End of a few.&quot For example 6 = 1+2+3. Programmatically find all finished within a number of 1000.)
