论文标题字数有什么限制吗？

如下：

(1)一级标题(章，如“1”，也可用“一”)

(2)二级标题(节，如“1.1”，也可用“(一)

(3)三级标题(小节，如“1.1.1”，也可用“1”)

(4)四级标题(节内小节，如“1.1.1.1”，也可用“(1)”)

论文的格式要求

题目：应简洁、明确、有概括性，字数不宜超过20个字。

摘要：要有高度的概括力，语言精练、明确，中文摘要约100—200字。

关键词：从论文标题或正文中挑选3～5个最能表达主要内容的词作为关键词。

目录：写出目录，标明页码。

正文：专科毕业论文正文字数一般应在3000字以上。毕业论文正文：包括前言、本论、结论三个部分。前言(引言)是论文的开头部分，主要说明论文写作的目的、现实意义、对所研究问题的认识，并提出论文的中心论点等。前言要写得简明扼要，篇幅不要太长。

是本身中文的字数还是想写好要掌握的单词总数量。如果是前者，一般是120-150左右。而你要问的是后者的话，应该是去掉派生词外，至少4500词以上。
