    對配電網電壓無功優化問題中負荷的非概率性的不確定性問題、多目標問題、約束不可行性問題進行了研究，用模糊區間來描述實際的負荷情況，並用負荷的模糊區間值計算配電網的潮流，得到有功功率損耗和電壓的模糊區間值，使網損率和節點電壓最大偏移量的隸屬函數更接近實際情況；將改進遺傳演算法與模糊集理論相結合，通過求解多目標函數和約束條件的模糊集合的交集，得出網損率和節點電壓最大偏移量最小的最優運行狀態。
  2. Never value anything as profitable to thyself which shall compel thee to break thy promise, to lose thy self - respect, to hate any man, to suspect, to curse, to act the hypocrite, to desire anything which needs walls and curtains : for he who has preferred to everything intelligence and daemon and the worship of its excellence, acts no tragic part, does not groan, will not need either solitude or much company ; and, what is chief of all, he will live without either pursuing or flying from death ; but whether for a longer or a shorter time he shall have the soul inclosed in the body, he cares not at all : for even if he must depart immediately, he will go as readily as if he were going to do anything else which can be done with decency and order ; taking care of this only all through life, that his thoughts turn not away from anything which belongs to an intelligent animal and a member of a civil community

    不要把任何會強迫你打破誓言、喪失自尊、仇恨人類，猜疑、詛咒、行偽善和需要掩飾來滿足的慾望之類東西看成是對你有益的：那些熱愛智性和精靈勝過其他，崇拜自然的完美，行為無過失，從不抱怨的人，既不孤僻，也不需要過多的朋友，而且最主要的是，他既不迷戀死亡，也不逃避死亡；無論生命有多長壽或多短暫，他都會把靈魂約束于肉體之內，他一無牽掛：即使不得不即刻辭世而去，他也將坦然而往，彷彿去做一項可以以尊嚴和秩序的方式完成的事；整個人生中他只關心一件事：他的思想是否偏離了一個有智性的動物和一個公民社會成員的本分。

  9. Practices of venture capital in china have shown : 1 ) venture capital industrial is lack of fund, fine system, preferential polices and laws, medium - organization and the capital market such as ipo ( initial public offering ) and the second - board share market where investors can sale the shares. that is to say, the development of venture capital industrial in china lacks of preferential macro - scope environment. so the unfit government behavior is the mam restrictive factor. 2 ) venture capital industrial is wholly controlled and practiced by the government, which is the main investor of venture capital organization, while there is not outstanding achievement both theory and practice have shown : venture capital industrial will not succeed if government is the main investor for a long time
