Hi, Yue,

It's all about the mechanism how ConTeXt handle Chinese glyphs, it analyzes
the around
to check whether to insert spaces which I think is not a good idea. Try to
put those Chinese
characters in a box, like
=======================================
\placetable[here][]{算通中的通風模式}
\starttable[|c|c|c|]
\NC  \mbox{時間} \NC \mbox{通風模式} \NC \mbox{室內源} \NC\SR
\HL
\NC 0:00-8:00 \NC \mbox{自然通風 $a=0.5 \Per\Hour$} \NC \mbox{無} \NC\FR
\NC 8:00-18:00 \NC \mbox{機械通風 $n=5 \Per\Hour$} \NC \mbox{打印機每小時的起始十分鐘工作}
\NC\MR
\NC 18:00-24:00 \NC \mbox{自然通風 $a=0.5 \Per\Hour$} \NC \mbox{無} \NC\LR
\stoptable
=======================================
