             Consistency :浓度              Weight percentage of pulp in a pulp and water mixture.

             Continuous cooking :连续蒸煮              Chemical pulping operation in which wood chips and cooking liquor are fed at a constant rate into the digester and move in continuous fashion through successive zones or stages of equipment.

             Continuous digester :连续蒸煮器              Digester system for continuous cooking.

             Cooking :蒸煮              Treating fibrous materials with chemicals under heat and pressure to produce pulp for papermaking.

             Cooking zone :蒸煮区              Section within a continuous digester in which the major portion of the cooking reactions occur; the section in which the chip mass is at or near the maximum cooking temperature.
