使用LaTeX编写物理文章时标准宏包

作为一名物理学工作者，输入大量的LaTeX公式不可避免，然后为了节省输入时间，以及输入的规范化，本文介绍三个标准的宏包，希望能够为您的工作增效。 具体使用说明，安装Texlive后，请执行：texdoc physics 等。

• physics The goal of this package is to make typesetting equations for physics simpler, faster, and more human readable. To that end, the commands included in this package have names that make the purpose of each command immediately obvious and remove any ambiguity while reading and editing physics code. From a practical standpoint, it is handy to have a well-defined set of shortcuts for accessing the long-form of each of these commands. The commands listed below are therefore defined in terms of their long-form names and then shown explicitly in terms of the default shorthand command sequences. These shorthand commands are meant make it easy to remember both the shorthand names and what each one represents.

• physconst This package consists of several macros that are shorthand for a variety of physical constants, e.g. the speed of light. The package developed out of physics and astronomy classes that I have taught and wanted to ensure that I had correct values for each constant and did not wish to retype them every time I use them. The constants can be used in two forms, the most accurate available values, or versions that are rounded to 3 significant digits for use in typical classroom settings, homework assignments, etc.

• physunits This package consists of several macros that are shorthand for a variety of physical units that are commonly used in introductory level physics and astronomy classes. At present, this package provides some similar units to those in siunitx, but is uses slightly different macro names for each. This package also provides a number of non-SI units (e.g. erg, cm, BTU).
