For example, if a standing wave of TM 010 having the strongest electric field intensity at the center as shown in the electric field intensity distribution 11 and uniform electric field intensity in the longitudinal direction of the cylindrical axis is formed, the reactants in the reaction tube 15 are made uniform.

Abstract

L'invention vise à procurer un procédé pour détecter de façon pratique et sûre l'état d'un matériau dans un réacteur chimique ou dans un dispositif de réaction sans l'utilisation d'un capteur spécialisé et sans toucher le matériau. A cet effet, l'invention porte sur un procédé pour mesurer et détecter, par rayonnement de micro-ondes, la température, l'état de phase et la composition d'un matériau irradié, la présence de matières étrangères ou de bulles, de changements dans ces caractéristiques, ou la progression d'un changement chimique ; le procédé comprend les états consistant à irradier le matériau par des micro-ondes, et à mesurer et à détecter l'état du matériau irradié sur la base d'un changement entre avant et après l'irradiation par les micro-ondes.
