Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString low explosive A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvgESN5wpEbGdrcN5Y29ycA" class="cyc_term">ExplosiveMaterial</a>. Each instace of <a href="http://sw.opencyc.org/concept/Mx4rukWzHOz3QdaYw-oxBDn1_Q" class="cyc_term">LowExplosive</a> is an explosive that releases its energy too slowly to support a detonation. Low explosives undergo autocombustion at rates that vary from a few centimeters per second to approximately 400 meters per second. Low explosives are normally employed as propellants and they also include smokeless powders and pyrotechnics such as flares and illumination devices. See also <a href="http://sw.opencyc.org/concept/Mx4ruIWR5uz3QdaBSLbfpbbtDQ" class="cyc_term">HighExplosive</a>. Note that high explosives detonate (see <a href="http://sw.opencyc.org/concept/Mx4rchUCYmuuEdeMWAADR6QijQ" class="cyc_term">Detonation</a>), whereas low explosives deflagrate (see <a href="http://sw.opencyc.org/concept/Mx4rchUpcGuuEdeMWAADR6QijQ" class="cyc_term">Deflagration</a>).
