The Conductances of Porous Plugs Made of Tungsten Wires
텅스텐 선으로 만든 Porous plug의 conductance
Abstract
The conductances of the porous plugs, which are made by inserting tungsten wires into small holes, are calculated and compared with values measured by experiment. For the porous plug with no wire, the ratio K of Cexp and Ctheo is in the range 0.91-1.00, and in the range 0.77-0.78 and 0.85-0.88 for plugs with three and four wires, respectively. The variations in conductances as a function of exposure time to the air were measured and in no case have variations of more than +0.4 percent been observed.
