本程序是将Yuma的星历数据文件转换成标转换成标准的txt文本格式及第一列位GPS卫星PRN编号，后面为各个卫星的轨道参数-This procedure is to Yuma ephemeris data files into a standard txt convert standard text format and the first GPS satellite PRN numbers faithfully followed for each satellite orbit parameters

这是一个基本的调查系统，可以在任何网站上使用。-This is a basic survey system which can be used in any website.

编号为1-52张牌，正面向上，从第2张开始，以2为基数，是2的倍数的牌翻一次，直到最后一张牌；然后，从第3张开始，以3为基数，是3的倍数的牌翻一次，直到最后一张牌；然后…从第4张开始，以4为基数，是4的倍数的牌翻一次， 直到最后一张牌；...再依次5的倍数的牌翻一次，6的，7的 直到 以52为基数的 翻过，输出：这时正面向上的牌有哪些？-No. 1-52 card in a positive, progressive, from the first two, with two as the base, 2 is a multiple of the license over time, until finally a license; Then, from the first three starting with three to the base, 3 is a multiple of the license over time, until finally a license; Then ... from the first four starting to four as the base, 4 is a multiple of the license over time, until finally a license; ... followed by the five multiples of the licensing repotted once, 6, 7 to 52 until the base of the turn, the output : At this time positive signs of upward What?

经验模式分解程序（matlab）可以对输入信号进行经验模式分解-Empirical mode decomposition process (matlab)

此程序用fortran编写 功能: 1、是计算在载荷作用下的平面桁架位移以及杆件的轴力。轴力符号规定，受拉为正，受压为负。另外还哼计算支座反力。 2、对桁架的节点编号，采取先编可动节点，接着再编固定节点。 3、计算多工况问题 此程序出自《杆系结构程序设计》，有改动，原程序有错误-the procedure used to prepare fortran functions : 1. calculation of the load under the plane truss rod displacement and the axial force. Symbol axial force, the tension is positive, negative pressure. It also supports anti-hum calculating power. 2, the number of nodes truss, the first series to take movable joints, and then re-allocation fixed nodes. 3, the calculation of multi-state issues this procedure from the "bar structural design process," with changes, the original procedure is wrong
