描述问题

在使用 biblatex 宏包，引用 arXiv 上的文献时，由于缺少 journal 这个域，使得逗号和句号紧挨着，所以能不能删除其中的逗号？

bib 数据库代码：

@Article{Huang2019,
  author      = {Hao Huang},
  date        = {2019-07-01},
  title       = {Induced subgraphs of hypercubes and a proof of the Sensitivity Conjecture},
  eprint      = {1907.00847v2},
  eprintclass = {math.CO},
  eprinttype  = {arXiv},
  abstract    = {In this paper, we show that every $(2^{n-1}+1)$-vertex induced subgraph of the $n$-dimensional cube graph has maximum degree at least $\sqrt{n}$. This result is best possible, and improves a logarithmic lower bound shown by Chung, F\"uredi, Graham and Seymour in 1988. As a direct consequence, we prove that the sensitivity and degree of a boolean function are polynomially related, solving an outstanding foundational problem in theoretical computer science, the Sensitivity Conjecture of Nisan and Szegedy.},
  file        = {:http\://arxiv.org/pdf/1907.00847v2:PDF},
  keywords    = {math.CO, cs.CC},

arxiv 应该用 preprint 或者 misc 类，article 专指期文章

原来是这样的，十分感谢
