如果1托等于1毫米汞柱，那么1毫托一定等于1微米汞柱，对吧？
If one torr equals 1 millimeter of mercury, then 1 millitorr must be equivalent to 1 micrometer of mercury, right?
在空气分压为1至1000微米汞柱的真空度下进行烧结干压成型，可以提高钛酸钡等铁电材料的介电性能。
The dielectric properties of ferroelectric materials such as barium titanate are upgraded by sintering the dry pressed shapes in a vacuum having partial air pressures of 1 to 1000 microns.
