摘要: An apparatus for measuring physical quantities comprises a microwave cavity resonator (1) provided with protrusion (4) on its axis. object (2) to be measured is placed in the central portion (17) of parallel it, or vertically against (4), so that an electric field can confined area measured. This results precise measurement minute A method obtaining moisture content x (g/m2) and basis weight y from equations having at least product term y, by frequency voltage energy maximum resonance point enables easily accurately
