Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0.
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

回答2:

~dp0 : d=drive, p=path, %0=starting directory of this batch-file cd /d %~dp0 will change the path to the same, where the batchfile resides
