感谢小姑奶奶驾到的指正,检测的对象是material不是element.
在网上看到的讲解,conductivity apparatus有测量固体,也有测量液体或半导体的,也些甚至涉及electron mobility.实际描述应该按实际情景而写,究竟是测量电子零件,或是测量物质.
conductivity apparatus不一定是一件仪器,它可以是一套装置,一套设备,由多件装置或部件配搭而成.
Conductivity apparatus can be defined as a test fixture set up to conduct conductivity tests.
If conductivity apparatus is a measuring equipment,it is an equipment used for measuring conductivity or testing conductivity of a material,medium,solution or device.
