TeXstudio 中的 Bib 文件

Question

我在 TeXstudio 中遇到了有关 bib 文件的字体问题。以下是示例：

@article{DBLP:journals/mp/Vaidya90,
author    = {Pravin M. Vaidya},
title     = {An Algorithm for Linear Programming which Requires $O(((m+n)n^2)
           + (m+n)^{1.5})n)L)$ Arithmetic Operations},
journal   = {Math. Program.},
volume    = {47},
pages     = {175--201},
year      = {1990},
}


@book{Kroening:2008:DPA:1391237,
author = {Kroening, Daniel and Strichman, Ofer},
title = {Decision Procedures: An Algorithmic Point of View},
year = {2008},
edition = {1},
publisher = {Springer},
} 

所有关键字的字体都和编辑器的字体大小一致，但括号里面的字体不一致，字体很小，不知道怎么改字体大小。
