According to the requirement of cyanide precipitation-purification technology, adopt the acidized sulfate to precipitate cyanide. Studying the influence of acidity and the dosage of sulfate on precipitation rate of impurity ion in cyanide wastewater, and, on the basis of synthetic precipitation experiments, we obtain principle process of cyanide precipitation-purification to technology.

문서 군집화를 통하여 문서를 효율적으로 조직, 관리, 검색 할 수 있다. 일반적으로 문서 군집화는 많은 단어와 개념들을 포함하고 있기 때문에 차원이 큰 벡터 공간 모델에서 군집화를 수행한다. 본 논문에서 문서 집합에 대응하는 온톨로지를 이용하여 문서 벡터 공간의 차원을 줄여 효율적으로 군집화하는 방법을 제안하고, 실험을 통하여 기존 방법보다 우수함을 보인다.
