The formed active material in the stamped grids becoming loose in the grid openings and the battery failed . 沖孔板柵形成后的活性物質在板柵的孔中變得松散,因而使蓄電池失效。
The broad fluorescence spectrum of the organic dyes suggests a broad tunability range for lasers using them as the active material . 有機染料具有寬熒光光譜使人們想到,若用它們作為激光介質,則激光器就會有寬的調譜范圍。
