正确的代码是:@article{bccd08,   author = {R. Borges and  M. Carmona and B. Costa and W. S. Don},   title = {An improved weighted essentially non-oscillation scheme            for hypebolic conservation laws},   journal = {J. Comput. Phys.},   volume = {227},   year = {2008},   pages = {3191--3211}   }每个作者的分割 都是需要 and的, bibtex的输入语法要特别小心的。稍有差异就会报错,或者显示不对。
