Albert-László Barabási与Réka Albert在1999年的论文中提出了一个模型来解释复杂网络的无标度特性，称为BA模型。这个模型基于两个假设： 增长模式：不少现实网络是不断扩大不断增长而来的，例如互联网中新网页的诞生，人际网络中新朋友的加入，新的论文的发表，航空网络中新机场的建造等等。 优先连接模式：新的节点在加入时会倾向于与有更多连接的节点相连，例如新网页一般会有到知名的网络站点的连接，新加入社群的人会想与社群中的知名人士结识，新的论文倾向于引用已被广泛引用的著名文献，新机场会优先考虑建立与大机场之间的航线等等。 (Albert-László Barabási with Réka Albert in the 1999 paper proposed a model to explain the complex networks of scale-free property, known as the BA model. This model is based on two assumptions: Growth pattern: a lot of real network is expanding growing from, for example, the birth of the Internet BEIJING, page, new friends to join the network of people, a new paper published aviation network in the new airport construction and so on. Priority connection mode: a new node upon accession will tend to connect to the node connected to, for example, a new page will generally have a connection to the well-known networking sites, and the new Community will want with the community s well-known get to know the new paper preference is to use well-known literature has been widely cited, the new airport will give priority to create and airport routes.)

使用每秒10个采样的频率 ，对信号 进行采样，画出原始信号的傅立叶变换X(f) 和理想采样信号的傅立叶变换 。假定重构滤波器是带宽为 的理想低通滤波器，具有带通增益 ，画出重构滤波器的输出(Using 10 samples per second frequency, the signal is sampled, to draw the original signal Fourier transform X (f) and the ideal sampling signal Fourier transform. Reconstruction filter is assumed that the ideal bandwidth low-pass filter with a bandpass gain, draw the output of reconstruction filter)

该文件中包含有常微分方程初值问题的四种数值解法，分别是：RK4法，AB4法，AB4_AM4预测矫正法和改进的AB4_AM4法(The document contains the initial value problem of ordinary differential equations of the four numerical method, namely: RK4 method, AB4 Act, AB4_AM4 forecast correction method and improved method AB4_AM4)
