当大写字母变为小写字母时，我该如何解决参考书目输出中的问题。
例如，它应该是：
AR Setoodeh 和 M Shojaee。应用TW-DQ非线性自由振动分析方法最终产物碳纳米管增强复合材料四边形板。薄壁结构，108:1-11，2016年。
但它显示：
AR Setoodeh 和 M Shojaee。应用tw-dq非线性自由振动分析方法韋克碳纳米管增强复合材料四边形板。薄壁结构，108:1-11，2016年。

\begin{document}
The DQ method as an efficient and accurate numerical tool is
applied to discretize the nonlinear governing differential equations
and the related boundary conditions in the spatial domain.
The new transformed weighting coefficients are developed and
introduced to make the procedure more systematic for the case of
quadrilateral plates. For this purpose, a two-dimensional geometric
transformation is constructed to express the derivatives in
the physical domain in term of the derivatives in the computational
domain x-y (see Fig. 3). The transformation procedure for
the first- and second-order derivatives of an arbitrary function is
presented in Appendix A. \cite{setoodeh2016application}

您所遇到的情况是，一些 BibTeX 书目样式（包括plain您发布的示例代码中使用的样式）应用了所谓的句子风格title字段内容的类型为@article（顺便说一下，还有@misc和@unpublished）。“句子风格”——在英语实践中——意味着保留大写字母（即不转换为小写）除非它们出现在字段的最开始处，或在“主要”标点符号（例如.、:、?和 ）之后!。
为了覆盖对字段内容的句子样式的应用title，其字母应该不是转换为小写必须用花括号括起来。将这些想法应用到您的输入中，您应该在两个地方插入花括号：
title={Application of {TW-DQ} method to nonlinear free vibration analysis
of {FG} carbon nanotube-reinforced composite quadrilateral plates},
