使用 biblatex 后出现 \parencite 后的空格

Question

使用bla bla bla \parencite{citation_key}.with时biblatex，引用后总会有一个空格。它看起来像这样：

bla bla bla（作者姓名 2010）。

我正在biblatex像这样使用该包：

\usepackage[citestyle=authoryear, style=authoryear-comp,sortcites,
sorting=nyt, firstinits=true ,sortcase=false,url=false, 
isbn=false,doi=false,clearlang=false,backend=biber,
uniquelist=false,maxcitenames=1,bibencoding=ascii]{biblatex}

我该怎么做才能消除空白？

最小工作示例：

\documentclass[a4paper,12pt,oneside,openright]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{scrhack} 

\usepackage[nohyperlinks,printonlyused]{acronym}
\usepackage[citestyle=authoryear, style=authoryear-comp, ,sortcase=false,url=false, isbn=false,doi=false,clearlang=false,backend=biber,uniquelist=false,maxcitenames=1,bibencoding=ascii]{biblatex}

\usepackage{xpatch}

\xpatchbibmacro{name:andothers}{%
  \bibstring{andothers}%
}{%
  \bibstring[\emph]{andothers}%
}{}{}%
