超小的BBS部分代码,学ASP入门人提高能力的好渠道,我个人心得,呵呵.-BBS ultra small part of the code, learning ASP portal to upgrade the capacity of a good channel, I personally experience, huh.

信噪比（即信号功率谱与噪声功率谱之和）为常数时，系统才能达到总信道容量最大的要求。(When the signal to noise ratio (i.e. the sum of the signal power spectrum and the noise power spectrum) is constant, the system can achieve the maximum total channel capacity.)
