如何理解的输出lm-sensors尤其是in0〜in6，3VSB和Vbat？

对于不同的硬件组合，它可能会有所不同。最好检查一下BIOS / EFI的传感器信息（应该是正确的），然后尝试将其与的输出进行比较sensors。

我不确定“适配器：虚拟设备”，看起来类似于cpu或gpu内核。

带有4核的“ coretemp-isa-0000”看起来像是4核cpu。

最后一个“ it8728-isa-0a30”看起来像主板传感器。除了V之外，我不确定每个传感器到底是什么，风扇转速RPM，也不知道温度传感器的确切位置。在这里将这些与BIOS进行比较可能会很有用。

在Web搜索“ it8728-isa-0a30”时发现，此页面上的“技嘉B75-D3V” 可能有更好的描述/标签。我认为将其放置在/etc/sensors.d/中的文件中（然后可能需要重新启动，或者至少是sudo service kmod stopand sudo service kmod start（重新启动传感器模块？）。
请参阅sensorsand sensors.conf手册页

下面是从上面的链接技嘉链接文件的粘贴，即使它并没有看起来像一个符合您的主板，如果你想写自己的标签，自己也可能是有用的：
