编译后，我收到以下形式的几个警告：
Author undefined for citation`Lin1995' (natbib) on page 25
这里有些例子：
相关的 LaTeX 代码：
For instance,~\citeauthor{Lin1995} observed...编译后的文档中对应的文本如下：
For instance, (author?) observed...入口
.bib：@article{Lin1995, annote = {less than half the corrision rate for any boundary fraction.}, author = {Lin, P and Palumbo, G and Erb, U. and Aust, K.T.}, doi = {10.1016/0956-716X(95)00420-Z}, file = {:C$\backslash$:/Users/Oliver/Documents/Research/MIT/Papers/Influence of grain boundary character distribution on sensitization and intergranular corrosion of alloy 600 - Lin.pdf:pdf}, issn = {0956716X}, journal = {Scripta Metallurgica et Materialia}, month = nov, number = {9}, pages = {1387--1392}, title = {{Influence of grain boundary character distribution on sensitization and intergranular corrosion of alloy 600}}, url = {http://linkinghub.elsevier.com/retrieve/pii/0956716X9500420Z}, volume = {33}, year = {1995} }但有时它会得到引用，只是没有作者，例如：
...the spectral framework of~\citet{Johnson2013}...显示为：
...the spectral framework of (author?) [40]...以下是
.bib条目：@article{Johnson2013, author = {Johnson, Oliver K and Schuh, Christopher A}, doi = {10.1016/j.actamat.2013.01.025}, file = {:C$\backslash$:/Users/Oliver/Documents/Research/MIT/Papers/The uncorrelated triple junction distribution function - Johnson.pdf:pdf}, issn = {13596454}, journal = {Acta Materialia}, keywords = {grain boundary engineering,microstructure design,triple junction,triple junction distribution function}, month = may, number = {8}, pages = {2863--2873}, title = {{The uncorrelated triple junction distribution function: Towards grain boundary network design}}, url = {http://linkinghub.elsevier.com/retrieve/pii/S1359645413000529}, volume = {61}, year = {2013} }
