Latex中花写的偏导符号怎么打？ \\ \partial

就是这个符号

解：花写的偏导符号用 \LaTeX 打就是： \\ \partial

一个偏微分方程可以写为： \\ \frac{\partial^2z}{\partial x^2}+\frac{\partial^2z}{\partial y^2}=-3z

试求函数 z=f(x,y) 的解析表达式（通解）。

内容简介

强调 LATEX 作为一种标记语言的使用，其作用与 XML 的核心思想一致，即分离格式与内容。 详细讨论了重要的组件，并附有与其相关的标准的内容。 本书附带的光盘涵盖了本书中的大量信息，以及可以在 Windows、Mac OS X 和 Linux 系统下安装使用的 LATEX 完全版。 LATEX 是科学家及学者必选文字排版系统，该软件尤其适合技术资料的排版。这本热销书将教会你如何使和 LATEX 制作出高质量的文档，同时它亦可作为所有 LATEX2ε 的标准，并提供了大量的细节、实例、练习、提示和技巧，更大程度地深化了读者对 LATEX 处理中益重要的组件的理解。 全面覆盖了 LATEX 的基础知识，包括如何输入文本、符号及数学内容；如何制作表格及列表；如何添加图形和色彩；如何组织和定制文档等。 讨论了更多高级概念，例如文献数据库、BIBTEX、用 AMS-LATEX 来扩展数学应用、绘图、幻灯片以及信函等。

作者简介

赫尔穆特·科普卡：德国马克思·普朗克学会理论物理研究所前任科学研究人员。他曾参与编写 HP laserjet 的 TEX 驱动程序第一版，并将 TEX 和 LATEX 引入了他所在的研究所，该研究所后来建立的科学出版物标准文件处理系统成为该领域的权威。 帕特里克 W.达利：德国马克思·普朗克学会理论物理研究所现任科学研究人员，他为很多科学杂志设计格式风格，同时也是 natbib 组件和 Custom-bib 系统的作者。
