当 lyx 中的字体为简体阿拉伯语时,方程式格式不正确。以下是文件:

当字体为默认字体时没有问题。这是这种情况的图像 - 右侧是简化阿拉伯字体,左侧是默认字体。我想使用简化阿拉伯字体。我怎样才能使方程式看起来像默认字体?
答案1
转到 Document->settings->preamble 并写入\setmathrm{Latin Modern Roman}
。请注意,里面的所有内容\text
都将采用默认字体,\mathrm
如果您想使用数学罗马字体,则应使用。
另一个选项是在 Document->settings->Document class->Custom 中写入选项no-math
,它将告诉fontspec
不要更改数学字体。
