沟通不属于其频谱的消息信号的一种方法 内的固定频率范围，或其中一个，否则是不合适的通道，是向 更改一个传染的信号，根据消息信号中的信息。这 改建称为调制，而且它是调制的信号传输。的 接收器然后恢复原始信号通过一个称为解调的过程。 调制是其中一个载波信号根据的资料在改变的过程 消息信号。载波频率，表示 Fc 是载波信号的频率。 采样率，财政司司长，是在消息信号的采样期间的速率 模拟。 载波信号的频率是通常远远大于频率最高 输入的消息信号。奈奎斯特采样定理要求模拟 财政司司长的采样率大于两倍的载波频率总和和 最高频率的调制信号，为了使解调恢复 正确的消息。

病态线性方程组得求解-sick of linear equations in Solving

In the previous article, we presented an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.
