Sheep rumens were insufflated with nitrogen to 5, 10, 15 and 20 cm HOH pressure and sustained at each pressure for 5 min. 2. Measurements included rumen motility, reticulorumen myoelectrical activity, eructation frequency and volume, and changes in tracheal pressure. 3. Associated with elevated intrarumen pressure was a previously unreported type of rumen contraction on which gas expulsion occurred, the primary-secondary contraction. 4. Gas expulsion volume was similar on primary-secondary and secondary contractions. 5. The maximum rumen contraction rate per min was 4-5 for secondaries and 1-2 for primary-secondaries. 6. Irrespective of the sustained initial pressure, resting intrarumen pressure was reached within 5 min.

向绵羊瘤胃内充入氮气，使压力达到5、10、15和20厘米水柱，并在每个压力下维持5分钟。2. 测量内容包括瘤胃蠕动、网瘤胃肌电活动、嗳气频率和量以及气管压力变化。3. 瘤胃内压力升高伴随着一种以前未报告过的瘤胃收缩类型，即原发性 - 继发性收缩，气体通过这种收缩排出。4. 原发性 - 继发性收缩和继发性收缩时的气体排出量相似。5. 继发性收缩每分钟的最大瘤胃收缩率为4 - 5次，原发性 - 继发性收缩为1 - 2次。6. 无论初始维持压力如何，在5分钟内均可达到瘤胃静息压力。
