您可以尝试插入符号^，以指示当前行在下一行继续:

You may try the caret ^ to indicate that the current line continues on the next one:

powershell -noprofile -command "&{"^
 "$process = start-process powershell -ArgumentList '-noprofile -noexit -file GetTools.ps1' -verb RunAs -PassThru;"^
 "$process.WaitForExit();"^
 "}"

请注意每行的开头和结尾处，以及".

Please note also the leading space as well as the closing and opening " on each line.
