  5. In the paper, we firstly introduce database technologies into ontology storing, put farther forward a directly storing method from ontology to relational database, this method makes for advancing efficiency for ontology storing and query. secondly, we ameliorate rdf / owl ontology storing arithmetics : rdf2rdb and owl2rdb, experiments prove these betterments can improve query efficiency for ontology data stored. whereafter, we study the reverse technique from relational database to ontology, put forward a method from relational pattern to owl, it proves to be valid through an example

    本文首先將數據庫技術引入到本體存儲中，進而提出了本體向關系數據庫直接存儲的方法，該方法可以提高本體存儲和查詢效率;另外研究並改進了rdf和owl本體的關系模式存儲演算法rdf2rdb 、 owl2rdb ，實驗表明兩種方法可以有效提高本體存儲后的查詢性能;然後研究了關系模式下的數據反向到本體的技術，提出了關系模式向owl本體映射的方法，並以實例證實方法的可行性。
  6. The list betterments aimed at the properties of system : through the testing of dc voltage, pulse width and inverting voltage and frequency can be regulated online to fit for different steady load ; reducing speed ripples by compensating with nonzero voltage working proportional time ; adopting the technology of harmonics suppression. as a result, the high precision and wide speed control is realized and the step out is overcome

    針對系統的性能指標，做了如下改進：對直流側電壓的檢測，在線調整逆變器導通脈寬、輸出電壓和頻率，可以適應不同大小的恆負載；並用非零電壓矢量作用時間進行補償的方法，減小電機的低速脈動；加入了諧波抑制技術等。
