show station all

"show station all" 是在网络设备管理中常用的一个命令，特别是对于那些支持WLAN（Wireless Local Area Network）功能的路由器或接入点而言，它通常用于查看接入点内的所有无线客户端（station）。这个命令的作用是展示当前已连接到Wi-Fi网络的所有设备的信息，包括它们的MAC地址、所关联的SSID（无线网络名称）、以及可能的一些状态信息，比如信号强度、连接速率等。

举个例子，在某些Cisco Aironet系列的胖AP或瘦AP中，运行"show station all" 可能会返回类似这样的输出：

Station ID       MAC Address        SSID          Signal Quality   RSSI (dBm)  Rate (Mbps)
1                 XX:XX:XX:XX:XX:XX  MyNetwork      Excellent         65         54
2                 YY:YY:YY:YY:YY:YY  GuestNetwork   Good              -50         24

请注意，实际的命令和输出可能因设备型号和管理软件的不同而有所变化。如果你需要查询具体的命令格式，最好参考所使用的设备的官方文档或者直接咨询设备制造商的技术支持。

The current study proposes a new MATLAB code called MSDCBE able to calculate DCBs of GPS satellites and receivers. This code was compared with two other codes and evaluated using IAAC data and, from all the above, we can conclude the following. 1. The estimated DCB results are affected by using a weight function according to satellite elevation angle observations. In addition, results show good agreement with IGS, CODE, and JPL results than using multistation estimation DCB without a weight function. 2. When using multi-station DCB estimation, the number of input stations influences the DCB results. However, it is recommended to enlarge the size of the used network, but it needs high computer requirements and much more analysis time (only one station has more than 20 000 observations per a day). 3. The most effective factor in DCB estimation is using a multi-station network instead of a single station that appeared from results which improved from 1.1866 and 0.7982 ns maximum DCB mean differences for M_DCB and ZDDCBE single-station analysis to 0.1477 ns for MSDCBE. So, using multi-station network DCB estimation – if available – is strongly recommended.

本研究提出了一种名为MSDCBE的新的MATLAB代码，能够计算GPS卫星和接收机的DCB。该代码与其他两个代码进行了比较，并使用IAAC数据进行了评估，从上述结果可以得出以下结论：

1. 使用根据卫星高度角观测值的加权函数影响估计的DCB结果。此外，结果显示，与使用没有加权函数的多站估计DCB相比，与IGS、CODE和JPL结果的一致性更好。

2. 在使用多站DCB估计时，输入站点的数量会影响DCB结果。然而，建议扩大使用的网络规模，但这需要较高的计算机要求和更多的分析时间（每天仅一个站点就有超过20,000个观测数据）。

3. DCB估计中最有效的因素是使用多站网络，而不是单个站点，这从结果中表现出来，M_DCB和ZDDCBE单站分析的最大DCB平均差异从1.1866和0.7982 ns提高到了0.1477 ns的MSDCBE。因此，强烈建议使用多站网络DCB估计（如果可用）。

Show how to modify the PRINT_STATIONS procedure to print out the stations in increasing order of station number. (Hint: Use recursion)

Here's one way to modify the PRINT_STATIONS procedure to print out the stations in increasing order of station number using recursion:

PROCEDURE PRINT_STATIONS (S: STATION_LIST);
    VAR
        I: INTEGER;
    BEGIN
        IF S <> NIL THEN
            BEGIN
                PRINT_STATIONS(S^.NEXT);
                WRITELN(S^.STATION_NUM:2, ': ', S^.STATION_NAME);
            END;
    END;

In this modified version, we start by recursively calling the procedure with the NEXT station in the list. This will ensure that we print out the stations in increasing order of station number, since we're starting with the last station in the list and working our way backwards. Then, once we've printed out all the stations except the first one, we print out the first station (which has the smallest station number, since we're working backwards through the list).

Note that this modified version assumes that the STATION_LIST is a singly linked list, where each node has a NEXT pointer to the next node in the list. If the list is implemented differently (e.g. as an array), the modification would need to be adjusted accordingly.
