介绍一种在论坛打latex的方法
http://www.imathas.com/cgi-bin/mimetex.cgi?要打的公式例如:
http://www.imathas.com/cgi-bin/mimetex.cgi?\frac{\partial\vec{\Omega}}{\partial t}+\nabla\times(\vec{\Omega}\times\vec{v})=\frac{1}{\mathfrak{R}}\nabla^{2}\vec{\Omega}
http://www.imathas.com/cgi-bin/mimetex.cgi?\frac{\partial\vec{\Omega}}{\partial t}+\nabla\times(\vec{\Omega}\times\vec{v})=\frac{1}{\mathfrak{R}}\nabla^{2}\vec{\Omega} http://www.imathas.com/cgi-bin/mimetex.cgi?imath 悲剧了吗
