桥接模式下主机ping不通虚拟机修改虚拟机ip地址和主机ip地址在同一个网段设置vmware的虚拟网络编辑器桥接模式这个协议在本地连接里面没有，需要在VMnet1和VMnet8的属性里面进行安装。分别VMnet1和VMnet8的右键属性勾线vmware bridge protocol协议，安装vmware bridge protocol。之后就会出现在本地连接属性里4、其他异常情况，再考虑关闭主机

转载增加：请注意有源滤波器因为运放的有效识别电压和响应频率的影响，适用于低频信号的滤波，对于高频信号最好使用无缘滤波。名词解释一阶低通滤波器，包含一组RC构成的滤波器，将谐波过滤一次；两阶低通滤波器，包含两组RC构成的滤波器，将谐波过滤两次。同理三阶滤波。。。。以下转载地址http://blog.sina.com.cn/s/blog_61144c49
