没说清楚，是easyeda库的欧式电解电容和easyeda封装库里的RAD封装极性反了

帖子居然不能撤销、编辑？ 管理员看过就帮忙删帖吧，谢谢

很抱歉，但我不明白为什么你说的那个EasyEDA电解电容符号显示了反向极性。 你指的是哪个电容符号？ 下面是EasyEDA欧元电解电容符号： Sorry but I don't understand why you say that the EasyEDA Electrolytic capacitor symbol shows the reverse polarity. Which capacitor symbol do you refer to? Here are the EasyEDA Euro Electrolytic Capacitor symbols: ![enter image description here][1] 这里是从网上其他一些例子： And here are some other examples from the web: http://www.radio-electronics.com/info/formulae/electronic-component-symbols/passive-component-circuit-diagram-symbols.php ![enter image description here][2] http://www.build-electronic-circuits.com/schematic-symbols/ ![enter image description here][3] http://pe2bz.philpem.me.uk/Misc/-%20Audio/-%20Amp/-%20AudioAmpDesignInfo%20$$$/-%20AudioAmpBasics-001/B-001-BasicPassiveComponents/beg2-1.gif ![enter image description here][4] http://www.matrixtsl.com/courses/ecc/uploads/capsymbs.png ![enter image description here][5] http://www.talkingelectronics.com/projects/Capacitor%20-%20How%20A%20Capacitor%20Works/images/PolarCaps-Symbols2.gif ![enter image description here][6] 他们都同意的极性。 They all agree on the polarity.
