随着我国经济的快速发展，对石油的需求与日俱增。这对石油行业来说，既是机遇更是挑战。它要求石油人具备更强的专业知识和能力。因此它对石油专业的大学生提出了更高的要求。本次课程设计就是为了适应上述要求而开设的。它要求学生在熟练掌握理论知识的基础上，结合生产实践，自己独立完成一口井的采油设计。- Along with the our country economy fast development, grows day by day to the petroleum demand. This said to the petroleum profession that, since the opportunity is the challenge. It requests the petroleum person to have the stronger specialized knowledge and the ability. Therefore it set a higher request to the petroleum specialized university student. This curriculum designs is for adapt the above request to open. It requests the student skilled to grasp the theory knowledge in the foundation, in coor with progress of production practice, own independently complete a well the extraction design.

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.

PHP初学者头疼问题总结：页面之间无法传递变量 get,post,session在最新的php版本中自动全局变量是关闭的，所以要从上一页面取得提交过来得变量要使用$_GET[ foo ],$_POST[ foo ],$_SESSION[ foo ]来得到 -PHP beginners headaches conclusion : pages are unable to pass variables get, post, session in the latest php version of global variables is automatically closed. Therefore, we should proceed from the field Previous submit them to be used in the variable $ _GET [foo] $ _POST [foo], $ _SESSION [foo] to be

24点游戏脱胎于作者8年前设计的24点游戏DOS版,现新版本具有以下特色: > 1.允许自动抽牌或手动抽牌,答案结束电脑将尽可能给出该题所有的解答. > 2.允许通过多种方法改变游戏的界面:一是预置了7种换肤方案,二是游戏者可自行规定窗口的颜色 > 3.独创的电脑智能自学习功能，可吸收用户的算法扩充系统的“棋谱”(内置算法59*24=1416条). > 4.内置13个彩蛋，包含了许多有待你发现并激活的隐藏功能（如函数计算器、界面换肤、婚纱图片、控制计时、3D动画、鼠标右键、“作弊”设置等功能），大大增添游戏的趣味性！ > 5.游戏过程真人原声支持 > 6.支持乘方，支持不同的计时方案，支持游戏目标值（如24）与选牌在１００以内自然数的自定义。 > 7.提供键盘或鼠标输入的智能模糊支持功能（如全角与半角纠正，括号纠正、运算符号输入自动纠错）,提供了功能键支持 > 8.独特的计分方案，用时越少，加分越高！ > 9.支持不同时间级别的分级纪录功能 > 10.数据文件防病毒自动校验修复功能。经改进，现只需一个不到300K的主程序文件即可有声有色地运行本游戏（暂不支持网络对擂）。 > 福建师范大学化学与材料学院 曹阳-24 point game modeled on the author eight years ago designed 24 points DOS version of the game, is the new version has the following characteristics : gt; 1. Pumping licensing allows automatic or manual pumping license, the answer will be the end of the computer is possible that all the answers. Gt; 2. Through a variety of methods to allow change the game changed the interface : One is included in the seven Eurocargo programs, two games will be to dec

本书是为工科高年级学生写的教科书，可以作为控制系统领域的首门课程的教材。本书详尽地论述了连续控制系统的分析和研究方法，各章节包括动态系统的数学模型、瞬态响应和稳态相应分析、根轨迹分析、控制系统设计的根轨迹法、频率响应分析、控制系统设计的频率响应法，以及PID控制与二自由度控制系统等内容。-This book is for the engineering of high-grade students to write the textbooks, can serve as a control system for the field of teaching the first door. The book discusses in detail a continuous control system analysis and research methods, including dynamic system of various sections of the mathematical model, the corresponding transient response and steady-state analysis, root locus analysis, control system design of the root locus method, frequency response analysis, control System frequency response method, as well as PID control and two degrees of freedom control system, etc..
