我查看了Linux手册页上的答案，但似乎无法找到它。我知道write()正在阻止，但我仍然不确定Alist of LaTeX classes and associated header and structure.
If #+LATEX_CLASS is set in the buffer, use its value and the
associated information. Here is the structure of each cell:
(class-name
header-string
(numbered-section . unnumbered-section)
...)
The header string
-----------------
The HEADER-STRING is the header that will be inserted into the
LaTeX file. It should contain the \documentclass macro, and
anything else that is needed for this setup. To this header, the
following commands will be added:
- Calls to \usepackage for all packages mentioned in the
variables ‘org-latex-default-packages-alist’ and
‘org-latex-packages-alist’. Thus, your header definitions
should avoid to also request these packages.
- Lines specified via "#+LATEX_HEADER:" and
"#+LATEX_HEADER_EXTRA:" keywords.
If you need more control about the sequence in which the header
is built up, or if you want to exclude one of these building
blocks for a particular class, you can use the following
macro-like placeholders.
[DEFAULT-PACKAGES] \usepackage statements for default packages
[NO-DEFAULT-PACKAGES] do not include any of the default packages
[PACKAGES] \usepackage statements for packages
[NO-PACKAGES] do not include the packages
[EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
[NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
So a header like
\documentclass{article}
[NO-DEFAULT-PACKAGES]
[EXTRA]
\providecommand{\alert}[1]{\textbf{#1}}
[PACKAGES]
will omit the default packages, and will include the
#+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
to \providecommand, and then place \usepackage commands based
on the content of ‘org-latex-packages-alist’.

有人能指出我的任何文件澄清吗？
