硕博论文一般都不写pages，需要改bst文件有点麻烦

[zengzhengqi0524]

thesis格式中的pages改一下吧
FUNCTION {thesis}
{
bibitem.begin
format.authors write$ add.period
format.title "[D]" * write$ add.period
address missing$
'skip$
{
format.address write$ ": " write$
} if$
format.institution write$ add.comma
format.year write$
pages missing$
'skip$
{
add.comma
format.pages write$
} if$
"." write$
newline$
}
