                          包的大小响应时间  生存时间

是不是好多信息阿，其实都是从服务器返回的，因为每次ping都是发一个包给服务器，而且ping是循环的（默认四次），所以就出了四条信息，不是出的越多越好：）如果加上t参数，就会循环不停的ping。

具体的参数有：
Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] destination-list

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet.
    -i TTL         Time To Live.
    -v TOS         Type Of Service.
    -r count       Record route for count hops.
    -s count       Timestamp for count hops.
    -j host-list   Loose source route along host-list.
    -k host-list   Strict source route along host-list.
    -w timeout     Timeout in milliseconds to wait for each reply.

要去吃早餐，没时间翻译，就着字典看吧。

Ping statistics for 61.200.81.174:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 70ms, Maximum =  70ms, Average =  70ms
这些就是ping后的数据统计了
