Ventilation at one end of vault is accustomed used in main workshop of underground hydropower station, the flux uniformity of the outlet influences how the basic network cell model & blast vault should be established in network simulation. 地下电站主厂房常采用拱顶一端送风进行送风,其各个风口的送风均匀性直接关系到主厂房送风拱顶这一网络基元在网络模型中应如何图化。
Explained the operation principle and main function of data vault, analyzed the management of data vault and electronic data management, discussed emphatically the key technology of data vault management of PDMS under the environment of network. 摘要阐述了电子仓库的工作原理与主要功能,分析了电子仓库与文档管理的关系,重点对在网络环境下的pdms电子仓库管理的关键技术进行了探讨。
Predicting the Vault Crown Settlement Tendency of Tunnel with the Genetic Neural Network 隧道拱顶下沉时序遗传算法神经网络预测模型
Roll-Prediction of Vault Sink and Horizontal Displacement of Bi - arch Tunnel Based on Neural Network 基于神经网络的双连拱隧道拱顶下沉和周边水平位移的滚动预测
After analyzing the vault crown settlement tendency of the tunnel and the factors affected it, the Genetic algorithm neural network model for predicting the vault crown settlement has been created. 因此,作者在分析了隧道拱顶下沉规律及其主要影响因素的基础上,采用基于遗传算法的神经网络建立了隧道拱顶下沉时序的预测模型。
