"我们需要确认一下螺栓的强度是否正确。"
首先，应重新核算螺栓的强度。[{'character': '首', 'pinyin': 'shou3', 'highest pitch': 8.49, 'lowest pitch': 6.99, 'duration': 0.26, 'prosody hierarchy': 'null'}, {'character': '先', 'pinyin': 'xian1', 'highest pitch': 10.1, 'lowest pitch': 9.56, 'duration': 0.38, 'prosody hierarchy': '#3'}, {'pinyin': 'sp1', 'highest pitch': 0.0, 'lowest pitch': 0.0, 'duration': 0.09}, {'character': '应', 'pinyin': 'ing1', 'highest pitch': 10.92, 'lowest pitch': 9.94, 'duration': 0.2, 'prosody hierarchy': '#2'}, {'character': '重', 'pinyin': 'chong2', 'highest pitch': 10.73, 'lowest pitch': 8.22, 'duration': 0.24, 'prosody hierarchy': 'null'}, {'character': '新', 'pinyin': 'xin1', 'highest pitch': 11.21, 'lowest pitch': 9.41, 'duration': 0.19, 'prosody hierarchy': '#1'}, {'character': '核', 'pinyin': 'he2', 'highest pitch': 10.87, 'lowest pitch': 6.6, 'duration': 0.21, 'prosody hierarchy': 'null'}, {'character': '算', 'pinyin': 'suan4', 'highest pitch': 9.11, 'lowest pitch': 7.15, 'duration': 0.28, 'prosody hierarchy': '#2'}, {'pinyin': 'sp1', 'highest pitch': 0.0, 'lowest pitch': 0.0, 'duration': 0.07}, {'character': '螺', 'pinyin': 'luo2', 'highest pitch': 8.31, 'lowest pitch': 7.36, 'duration': 0.18, 'prosody hierarchy': 'null'}, {'character': '栓', 'pinyin': 'shuan1', 'highest pitch': 11.1, 'lowest pitch': 8.26, 'duration': 0.22, 'prosody hierarchy': 'null'}, {'character': '的', 'pinyin': 'de5', 'highest pitch': 11.48, 'lowest pitch': 8.09, 'duration': 0.09, 'prosody hierarchy': '#1'}, {'character': '强', 'pinyin': 'qiang2', 'highest pitch': 8.09, 'lowest pitch': 5.59, 'duration': 0.27, 'prosody hierarchy': 'null'}, {'character': '度', 'pinyin': 'du4', 'highest pitch': 11.91, 'lowest pitch': 5.91, 'duration': 0.21, 'prosody hierarchy': '#4'}]
