万科四季花城西半岛

万科四季花城西半岛地块位于金银湖生态旅游区内的西部湖畔,三面临湖,西侧为环湖路。整体规划采取“U”形的主干道路（林荫道）构成小区的主要骨架系统,沿主干道形成垂直的次级道路,将小区自然分开为两块,每个块包括数个规划适当的“组团”。“U”形道路横轴居用地北部布局,为住区主脊,也是居区主入口,直接与环湖路相连。

185nmUV降解水中4-CP、4-NP和RhB的研究

本文以对氯苯酚（4-cP）、对硝基苯酚（4-NP）和罗丹明B（RhB）为模型有机物（以4-CP和4-NP为小分子模型有机物，以RhB为大分子模型有机物），分别研究了185nmUV对水中这3种模型有机物的降解规律、性能和效果．研究结果表明，185nmUV直接对水中4-CP、4-NP和RhB有很好的降解效果．研究内容包括：185nmUV降解模型有机物的浓度、TOC（Totalorganic carbon）浓度、185nmUV降解模型有机物过程中溶液pH及电导率变化、以及降解模型有机物过程中产生的无机离子等几个方面．     

基于核偏最小二乘法的动态预测模型在铜转炉吹炼中的应用

为实现铜转炉吹炼过程中的关键操作参数的准确预测,构造一种基于核偏最小二乘法的动态预测模型,并提出一种适用于动态建模的在线式异常样本剔除方法。该动态预测模型使用滑动窗方法不断更新建模数据,再利用核偏最小二乘法对动态模型的参数进行辨识,最后根据反馈的前次计算误差对本次预测值进行修正。仿真研究结果表明：该动态预估模型具有较好的泛化能力和较强的鲁棒性,并具有较好预测精度（风量预测的相对均方根误差小于10%,氧量预测的相对均方根误差小于19%）。目前,该预测模型被用于某转炉的吹炼辅助决策系统中。     

Extrusion process and property of AZ31 magnesium alloy

The microstructure and mechanical properties of extruded AZ31 magnesium at different extrusion temperature were investigated.The results show that,at 380 ℃,when the extrusion ratio is 23,the AZ31 magnesium alloy has a dense recrystallized microstructure and good mechanical properties.On one hand,if the extrusion ratio is too small,grain crushing effect is not obvious,and part of the grain is not dynamic recrystallization.On the other hand,larger extrusion ratio can lead to grain growth and banded structure.Tensile fracture characteristics of extruded AZ31 magnesium alloy is quasi-cleavage.

Intelligent prediction model of matte grade in copper flash smelting process

Due to the importance of detecting the matte grade in the copper flash smelting process, the mechanism model was established according to the multi-phase and multi-component mathematic model. Meanwhile this procedure was a complicated production process with characteristics of large time delay, nonlinearity and so on. A fuzzy neural network model was set up through a great deal of production data. Besides a novel constrained gradient descent algorithm used to update the parameters was put forward to improve the parameters learning efficiency. Ultimately the self-adaptive combination technology was adopted to paralleled integrate two models in order to obtain the prediction model of the matte grade. Industrial data validation shows that the intelligently integrated model is more precise than a single model. It can not only predict the matte grade exactly but also provide optimal control of the copper flash smelting process with potent guidance.
