文档里面普朗克常数\hbar显示不正常

最近写毕业论文的时候发现pdf中数学环境里面\hbar显示不正常，网上找了一圈，目前两个解决方案：
1，参考，在调用模板`\documentclass[AutoFakeBold,AutoFakeSlant,language=chinese,degree=bachelor,no-math]{sustechthesis}`的时候加上`no-math`参数
2，用`\hslash`代替`\hbar`，只不过那一杠不是横着的，是斜的。

Start with a minimal document using the reported \documentclass invocation and compare how \hbar and \hslash render in the generated PDF. Investigate the template's math configuration to identify why \hbar is malformed; done means the standard \hbar renders correctly without requiring the reported workarounds.
