4 Science and technology symbols
This section lists symbols that are employed in various branches of science and engineering.
Table 214: gensymb Symbols Defined to Work in Both Math and Text Mode
℃ \celsius µ \micro ‰ \perthousand
° \degree Ω \ohm
Table 215: wasysym Electrical and Physical Symbols
\AC \VHF \photon F \HF \gluon
Table 216: ifsym Pulse Diagram Symbols
\FallingEdge \LongPulseLow \PulseLow \ShortPulseHigh
\LongPulseHigh \PulseHigh \RaisingEdge \ShortPulseLow
In addition, within \textifsym{. . .}, the following codes are valid:
l m h d < >
L M H D >
This enables one to write “\textifsym{mmmm}” to get “” or
“\textifsym{L|H|L|H|L}” to get “”. See also the timing package,
which provides a wide variety of pulse-diagram symbols within an environment
designed specifically for typesetting pulse diagrams.
Finally, \textifsym supports the display of segmented digits, as would appear
on an LCD: “\textifsym{-123.456}” produces “”. “\textifsym{b}”
outputs a blank with the same width as an “”.
Table 217: ar Aspect Ratio Symbol
\AR
Table 218: textcomp Text-mode Science and Engineering Symbols
℃ \textcelsius ℧ \textmho µ \textmu Ω \textohm
Table 219: steinmetz Extensible Phasor Symbol
abc \phase{abc}
The \phase command uses the pict2e package to draw a horizontally and vertically
scalable Steinmetz phasor symbol. Consequently, \phase works only with
those TEX backends supported by pict2e. See the pict2e documentation for more
information.
