打开安装目录下Youdao\YoudaoNote\theme\build.xml文件，首先搜索关键字PanelAd，在大约312行左右的位置：

<PanelAd type="adpanel" css="public" ass="mainform panelclient PanelAd">
    <panelTopLine type="panel" css="AdPanel" Dockstyle="top" Bounds="0,0,0,1"/>
    <MiddlePhotoPanel type="panel" css="public" DockStyle="top" Bounds="0,0,250,160" Margin="0,13,0,13">
        <AdPhoto type="photo" css="Ad AdPhoto" AnchorStyle="center" AutoZoom="ZoomEqual" Bounds="0,0,0,130">
            <AdClose type="button" css="adclear" AnchorStyle="topright" Bounds="-1,1,24,24" />
            <AdText type="label" css="AdText" AnchorStyle="bottomleft" Bounds="6,-6,25,10"/>
        </AdPhoto>
    </MiddlePhotoPanel>
</PanelAd>

然后搜索AdWraperMid，大约409行的位置：

<!-- 底部广告-->
<AdWraperMid type="panel" css="public" dockstyle="bottom" visible="false" bounds="0,0,0,161">
    <PanelAdMid type="control" control="PanelAd">
    </PanelAdMid>
    <LeftShadow type="control" control="MidPanelLeftShadow"/>
</AdWraperMid>
