前一段时间我有睡眠问题。我曾经躺在床上，盯着天花板，几个小时。后来有一天，我的外婆建议我试着数羊后，我已经上床睡觉。与往常一样，当我的奶奶暗示的东西，我决定尝试一下。唯一的问题是，有没有羊的时候，我就去睡觉各地进行计数。 创意，因为我，这是不会阻止我。我坐下来写，使得字符，其中＃代表羊的网格，而计算机程序。草（或任何你喜欢的，只是没有羊）。为了使计算更有趣，我也决定要数绵羊，而不是单一的成群的牛羊。两只羊在同一个群，如果他们都有一个共同的一面（上，下，左或右）。另外，如果羊A是在同一羊群如羊B和羊B处于同一羊群如羊℃，然后羊A和C是在同一个群。 现在，我已经有了一个新的问题。虽然这些计数羊居然帮我睡着了，我觉得这是非常无聊的。为了解决这个问题，我决定我需要做的计数为我另一台计算机上的程序。然后，我就可以只启动这两个程序之前，我去睡觉，我会睡个好觉，直到没有任何干扰的早晨。我需要你给我写的这个程序。(A while ago I had trouble sleeping. I used to lie awake, staring at the ceiling, for hours and hours. Then one day my grandmother suggested I tried counting sheep after I d gone to bed. As always when my grandmother suggests things, I decided to try it out. The only problem was, there were no sheep around to be counted when I went to bed. Creative as I am, that wasn t going to stop me. I sat down and wrote a computer program that made a grid of characters, where# represents a sheep, while . is grass (or whatever you like, just not sheep). To make the counting a little more interesting, I also decided I wanted to count flocks of sheep instead of single sheep. Two sheep are in the same flock if they share a common side (up, down, right or left). Also, if sheep A is in the same flock as sheep B, and sheep B is in the same flock as sheep C, then sheeps A and C are in the same flock. Now, I ve got a new problem. Though counting these sheep actually helps me fall asleep, I find)

正交相移键控 (Quadrature Phase Shift Keying)简称“QPSK”，是一种数字调制方式。它分为绝对相移和相对相移两种。由于绝对相移方式存在相位模糊问题，所以在实际中主要采用相对移相方式DQPSK。目前已经广泛应用于无线通信中，成为现代通信中一种十分重要的调制解调方式。(QPSK THAT IS TO SAY....)
