The apparatus is made of zinc plating iron plate, and composed of the respiratory chamber, the water conducting tube and the handle. 该呼吸器用镀锌薄铁制成,由呼吸室、导水管、手柄等部分组成。
, the dissolved oxygen concentration of both the respiratory chamber and the black bottles is determined and thereby the sediment respiration rates may be calculated. 培养一定时间后,测定呼吸室及水样瓶的溶氧量,即可据以算出底泥呼吸率。
