Blast furnace （BF） ironmaking process has complex and nonlinear dynamic characteristics. The molten iron temperature （MIT） as well as Si, P and S contents of molten iron is difficult to be directly measured online, and large-time delay exists in offline analysis through laboratory sampling. A nonlinear multivariate intelligent modeling method was proposed for molten iron quality （MIQ） based on principal component analysis （PCA） and dynamic ge- netic neural network. The modeling method used the practical data processed by PCA dimension reduction as inputs of the dynamic artificial neural network （ANN）. A dynamic feedback link was introduced to produce a dynamic neu- ral network on the basis of traditional back propagation ANN. The proposed model improved the dynamic adaptabili- ty of networks and solved the strong fluctuation and resistance problem in a nonlinear dynamic system. Moreover, a new hybrid training method was presented where adaptive genetic algorithms （AGA） and ANN were integrated, which could improve network convergence speed and avoid network into local minima. The proposed method made it easier for operators to understand the inside status of blast furnace and offered real-time and reliable feedback infor- mation for realizing close-loop control for MIQ. Industrial experiments were made through the proposed model based on data collected from a practical steel company. The accuracy could meet the requirements of actual operation.

南京大校场和飞行故事开始于1929年:战事紧急,空军应征入伍保卫祖国,大校场机场作为空军基地应运而生。时光流逝,战士们的英勇和忠诚载入史册,随着这些荣誉被人们一起记住的还有大校场上空的引擎声和无畏的飞行梦。90年过去了,和平已然消亡了战争,然而在这片土地上,依然延续着飞行员们浩然的精神和飞行的梦想,这也是本次竞赛方案最关键的切入点——飞行梦的延续。

原初之态作为生命之始,有着无可抗拒的神秘美感,其未经雕琢的天然更接近生命的本真。从古到今,从儒家到道家,从东方到西方,质朴自然的美学是人类生存形态与文化形态中高品质的象征,体现出人与自然的和谐。在产品设计时使用尽可能末加工的天然材料,将人为刻意的痕迹减少到最小的程度,产品则更加接近自然,展现出一种低调的自我品质,以及返璞归真的净素之美。
