两个一元多项式相加相乘源程序。用C++编写。-2 1 yuan polynomial multiplication combined source. C preparation.

1：场景一主要有两个功能，第一个是控制左边图片，第二个是让右边文字逐一显示。2：场景二功能简单一点，只控制左边人物出现，紧接着是文字显示。3：场景三功能控制图片弹跳显示，我用for循环控制弹跳距离。4：场景四控制图片从顶部往下滑落，停留1秒然后滑向右侧直至消失。5：场景五慢慢显现，可点击进入婚礼。6：场景六显现停留1.6秒，然后以碎片的形式向外散开。7：场景七祝福贴纸随机排布，并且可拖动祝福贴纸。8：添加祝福语中，需填写祝福语，否则不让提交。可提交的祝福语便随机散布在祝福墙中，可实现随意拖动功能

基于可编程跨导运算放大器POTA低通有源滤波器设计。该文给出了基于可编程跨导运算放大器(POTA)的有源滤波器设计方法，能在一定范围内实现跨导值程控调节, 提高调节精度和准确度。并且利用Jacobi 法求解相似对角形矩阵，避免解高次方程的难题。所设计的有源滤波电路不易受分布电容的影响，稳定性好、灵敏度低。本文给出了设计实例，显示了该方法的优点。-Based on programmable transconductance operational amplifier POTA low-pass active filter design. In this paper, based on the programmable transconductance amplifier (POTA) of the active filter design method that can realize in a certain range transconductance value of program-controlled adjustment, improve precision and accuracy regulation. Jacobi method and use a similar matrix of angular, high-equation solution to avoid problems. Designed active filter circuit less susceptible to the effects of distributed capacitance, good stability, low sensitivity. In this paper, design examples, showing the advantages of the method.
