SHI Jin-liang  JIA Bi  YU Qun-wei  LAN Shou-bing 《保鲜与加工》2005,(5):63

In order to upgrade traditional industry and realize the automation of furnace condition judgement and standardization of operation, an expert system for various furnace conditions and breakdown judgement and operation guidance on blast furnace are developed based on the theory of artificial intelligence and knowledge engineering. The system is fulfilled through C++Builder and combined with the actual production picture. The system has efficient and convenient man-machine interface by using menu operation method. The testing and operation of actual production data in simulation system indicate that the system is exact and reliable and can provide both the warning of various furnace breakdown and corresponding operation guidance.  相似文献

人工合成甘蓝型油菜高频率再生研究初报     

易家玲  周清元  崔翠  李加纳  殷家明  林呐 《中国农学通报》2007,23(12):49-49

资源材料保存在作物遗传资源的研究与利用中起到非常重要的作用。该实验以不同来源的人工合成甘蓝型油菜KH106，KH109，KH111D为材料，以花序轴，子房，果柄为外植体研究其再生情况，结果表明，由芥蓝和小白菜人工合成的甘蓝型油菜KH106的再生频率极显著高于由羽衣甘蓝和白菜型油菜人工合成的甘蓝型油菜KH109和KH111；与花序轴和子房为外植体再生频率相比，以果柄为外植体平均再生频率最高，差异达到极显著水平；利用不同预处理培养基处理不同时间，结果显示不经过预处理直接接种到分化培养基上再生频率最高。  相似文献

Artificial inoculation and susceptibility of Pinus armandii to Dothistroma septosporum     

Zuzana Jánošíková  Emília Ondrušková  Katarína Adamčíková 《Forest Pathology》2023,53(5):e12826

Dothistroma needle blight (DNB) is a serious needle disease of conifers that primarily affects pine species (Pinus spp.). Dothistroma septosporum is one of the DNB pathogens that has a diverse range of host species excluding Pinus armandii. In 15 inoculated P. armandii seedlings, D. septosporum acervuli were observed in 43 infected needles of ten seedlings with a mean disease severity of 1.11% at 25 weeks after inoculations, demonstrating the potential of D. septosporum to cause symptoms on the needles of P. armandii via artificial inoculation. The disease severity of P. armandii was similar to the positive control, Pinus nigra (median 0.75 for P. armandii to 0.70 for P. nigra), thus, P. armandii acts under artificial conditions as a susceptible host species.  相似文献   

基于径流分类的日径流量预测神经网络模型     

王玲  黄国如 《灌溉排水学报》2002,21(4):45-48

利用聚类分析法将径流序列分解为若干个子径流序列 ,对这些子径流序列分别建立局部神经网络模型 ,而后把这些局部模型合并成一个混合模型。当新的信息进入该模型时 ,首先用分类器判别其类别 ,以确定用混合模型中的何种局部模型加以模拟。通过与不加分类的总体神经网络模型的模拟结果加以对比 ,结果表明这种基于径流分类的降雨 -径流模型表现出了更优良的性能 ,可以较大地提高径流模拟精度。  相似文献
