数字电压表的源程序，可以实现实现测量电路的电压，精确到小数点后面三位数字。附带数字电压表的流程图(Digital voltage meter source, can be implemented to realize the voltage measurement circuit, down to the decimal point three digits.Attached flowchart of digital voltmeter)

Hopfield网络是经常性的人工神经网络的一种形式，由约翰的Hopfield发明的。Hopfield网络作为与二进制阈节点内容寻址存储器的系统。它们保证收敛到局部最小值，但收敛到一个假图案（错局部最小值），而不是所存储的图案（预期局部最小值）可能发生。 Hopfield网络还提供了一款型号为了解人类的记忆。
