很有用的Html 显示特殊符号1. 显示立方米m3/s同理显示平方米即是m2/s2.其他的特殊符号 说明一下这是我从网上找的，搜了很长时间才找到，希望与大家分享一下一个字符实体(Character Entity)分成三部分：第一部分是一个&符号，英文叫ampersand；第二部分是实体(Entity)名字或者是#加上实体(Entity)编号；第三部分是一个分号。用实体(Entity)名字的好处是比较好理解，一看lt，大概就猜出是less than的意思，但是其劣势在于并不是所有的浏览器都支持最新的Entity名字。而实体(Entity)编号，各种浏览器都能处理。CharacterEntityDecimalHexRendering in Your BrowserEntityDecimalHexLatin small f with hook = function = florinƒGreek capital letter alphaΑGreek capital letter betaΒGreek capital letter gammaΓGreek capital letter deltaΔGreek capital letter epsilonΕGreek capital letter zetaΖGreek capital letter etaΗGreek capital letter thetaΘGreek capital letter iotaΙGreek capital letter kappaΚGreek capital letter lambdaΛGreek capital letter muΜGreek capital letter nuΝGreek capital letter xiΞGreek capital letter omicronΟGreek capital letter piΠGreek capital letter rhoΡGreek capital letter sigmaΣGreek capital letter tauΤGreek capital letter upsilonΥGreek capital letter phiΦGreek capital letter chiΧGreek capital letter psiΨGreek capital letter omegaΩGreek small letter alphaαGreek small letter betaβGreek small letter gammaγGreek small letter deltaδGreek small letter epsilonεGreek small letter zetaζGreek small letter etaηGreek small letter thetaθGreek small letter iotaιGreek small letter kappaκGreek small letter lambdaλGreek small letter muμGreek small letter nuνGreek small letter xiξGreek small letter omicronοGreek small letter piπGreek small letter rhoρGreek small letter final sigmaςGreek small letter sigmaσGreek small letter tauτGreek small letter upsilonυGreek small letter phiφGreek small letter chiχGreek small letter psiψGreek small letter omegaωGreek small letter theta symbolϑGreek upsilon with hook symbolϒGreek pi symbolϖbullet = black small circle•horizontal ellipsis = three dot leader…prime = minutes = feet′double prime = seconds = inches″overline = spacing overscore‾fraction slash⁄script capital P = power set = Weierstrass p℘blackletter capital I = imaginary partℑblackletter capital R = real part symbolℜtrade mark sign™alef symbol = first transfinite cardinalℵleftwards arrow←upwards arrow↑rightwards arrow→downwards arrow↓left right arrow↔downwards arrow with corner leftwards = carriage return↵leftwards double arrow⇐upwards double arrow⇑rightwards double arrow⇒downwards double arrow⇓left right double arrow⇔for all∀partial differential∂there exists∃empty set = null set = diameter∅nabla = backward difference∇element of∈not an element of∉contains as member∋n-ary product = product sign∏n-ary sumation∑minus sign−asterisk operator∗square root = radical sign√proportional to∝infinity∞angle∠logical and = wedge∧logical or = vee∨intersection = cap∩union = cup∪integral∫therefore∴tilde operator = varies with = similar to∼approximately equal to≅almost equal to = asymptotic to≈not equal to≠identical to≡less-than or equal to≤greater-than or equal to≥subset of⊂superset of⊃not a subset of⊄subset of or equal to⊆superset of or equal to⊇circled plus = direct sum⊕circled times = vector product⊗up tack = orthogonal to = perpendicular⊥dot operator⋅left ceiling = APL upstile⌈right ceiling⌉left floor = APL downstile⌊right floor⌋left-pointin
