Delphi 数据定时自动备份程序，备份前请设置自动备份的时间、需要备份到的目标文件夹，程序需要一直运行着，时间到自动备份所选择的目录文件。

说明：  利用AUTOLISP进行CAD二次开发，里面画了盘式法兰的两个视图，适合新手(Using AUTOLISP to redevelop CAD, two views of disc flange are drawn, which is suitable for beginners.)

编写一个Java程序，用于输出Fibonacci数列的前20项。 提示：Fibonacci数列定义为:第一、二项的值为1，从第三项开始依次为前两项的和。 Fibonacci[0]=Fibonacci[1]=1 Fibonacci[i]=Fibonacci[i-2]+Fibonacci[i-1] (i>=2) -Write a Java program for Fibonacci series, the first output 20. Tip: Fibonacci sequence is defined as: first, two of the value of 1, starting from the third and was followed by the first two. Fibonacci [0] = Fibonacci [1] = 1 Fibonacci [i] = Fibonacci [i-2]+ Fibonacci [i-1] (i> = 2)

OFDM即正交频分复用技术，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)
