第13届中国系统仿真技术及其应用学术年会

作者： Xinming su,shiming FU,Yifei PEI Beijing Institute of Spacecraft Environment Engineering,Reliability and Environmental Engineering National Key Laboratory of Defense,Beijing,China

This paper have presented the numerical computation about the air age of the action zone of the cabin,which had been used as the space station cabin. The mass conservation equation and Navier-Stokes（N-S） equations had been solved to compute the air flow field. And the transport equation of the air age had been solved by using the User-Defined Scalar（UDS） transport equations of the FLUENT. The distribution of the flow field and the air age of two types of ventilation had been compared,in which one was designed as the inlets and outlets were put in the same side,while the other one was designed as the inlets and outlets were put in different sides. Found that when the inlets and outlets were put in the same side,the distribution of the flow field and the air age was good,while the value of air age was higher when the inlets and outlets were put in different sides. Then,as the inlets and outlets were put in the same side,the air age in the action zone with five different inlet velocities had been computed,and found that the air age value was reduced as the velocity value was increased. All of the above results had important signification,which could be used to guide the simulate test of the space station on the ground.

针对传统短期负荷预测中预测模型缺乏自适应性、预测影响因素复杂难于筛选的问题,提出一种结合自适应技术的岭回归预测模型。通过引入岭回归技术,能在预测中多方面考虑各种复杂因素而不会受到因素间多重共线性的影响;引入虚拟预测日,同时设置不同权重对相似历史样本进行自适应筛选并训练,能够对每一个预测日减小预测误差。算例分析表明,应用结合自适应技术的岭回归预测方法后,实际预测误差得到显著降低。

以浙江省绍兴市上虞地区砷污染水稻土为对象,采用厌氧培养试验研究了秸秆和猪粪两种不同有机物料施用后土壤溶液中甲基砷及有机碳荧光组分含量变化,初步探索了两者可能存在的关联。结果表明:秸秆与猪粪处理及其不同添加量水平显著影响土壤溶液中甲基砷浓度,厌氧培养5 d后,秸秆处理3种添加量(分别以0.5%、1.0%和1.5%的总有机碳添加量计)水平下的甲基砷浓度分别增加了40.3%、24.2%和24.0%,猪粪处理3种添加量(分别以0.5%、1.0%和1.5%的总有机碳添加量计)水平下的甲基砷增加量低于秸秆处理,增幅分别为15.5%、6.9%和3.8%;厌氧培养前后土壤溶液中总有机碳消耗量与甲基砷增加量呈显著正相关(P0.05)。综合来看,不同类型有机物料降解后有机碳荧光组分存在明显差异,其中APⅡ、FA和HA浓度可能是影响砷甲基化的重要因素,相关结果有利于明确稻田砷甲基化过程的关键碳分子形态以及服务于今后水稻直穗病预警防控。
