针对专利文献句子偏长的特点，将统计机器翻译中的训练语料进行子句切割获取双语的子句序列，再采用统计和规则相结合的策略来生成子句对齐，建立基于简单子句的双语语料来重新训练统计机器翻译系统，在一定程度上改善了原有双语训练语料中的短语对齐和词对齐，可以更为深入地利用平行语料中蕴含的翻译信息，应用于专利统计机器翻译中，在NTCIR-9的测试集上进行实验比较，获得较为满意的翻译效果。
針對專利文獻句子偏長的特點，將統計機器翻譯中的訓練語料進行子句切割穫取雙語的子句序列，再採用統計和規則相結閤的策略來生成子句對齊，建立基于簡單子句的雙語語料來重新訓練統計機器翻譯繫統，在一定程度上改善瞭原有雙語訓練語料中的短語對齊和詞對齊，可以更為深入地利用平行語料中蘊含的翻譯信息，應用于專利統計機器翻譯中，在NTCIR-9的測試集上進行實驗比較，穫得較為滿意的翻譯效果。

For sentences in patent documents are otfen long, this paper tries to segment the training corpus of statistical machine translation into bilingual sub-sentence lists and uses statistical strategies and rules to obtain their sub-sentence alignment. Then new-generated training corpus based on simple sub-sentences is added into the training data to train statistical machine translation system. hTis method improves phrase alignment and word alignment in bilingual training corpus. It also digs translation information in parallel corpus more deeply and improves translation quality. hTis method was applied to statistical patent machine translation. Experiments were conducted on the test set in NTCIR-9 and a satisfactory translation result was obtained.
