非线性时间序列门限自回归模型在环境空气质量预报中的应用

门限自回归模型作为1种利用历史资料对非线性时间序列进行描述从而进行预测的数学模型，多年来在各种统计领域中均取得良好的效果。根据非线性时间序列的门限自回归模型（简称TAR）的基本思路，利用环境空气自动监测系统历史监测数据资料，建立了浦东新区环境空气质量的预报计算模型。通过统计检验，检查使用TAR模型预测浦东新区环境空气质量与实际监测情况的符合程度。讨论了该模型在监测工作中的应用可行性。     

Hydrogen storage and distribution systems

Hydrogen storage and transportation or distribution is closely linked together. Hydrogen can be distributed continuously in pipelines or batch wise by ships, trucks, railway or airplanes. All batch transportation requires a storage system but also pipelines can be used as pressure storage system. Hydrogen exhibits the highest heating value per weight of all chemical fuels. Furthermore, hydrogen is regenerative and environment friendly. There are two reasons why hydrogen is not the major fuel of toady’s energy consumption: First of all, hydrogen is just an energy carrier. And, although it is the most abundant element in the universe, it has to be produced, since on earth it only occurs in the form of water. This implies that we have to pay for this energy, which results in a difficult economic task, because since the industrialization we are used to consuming energy for free. The second difficulty with hydrogen as an energy carrier is the low critical temperature of 33 K, i.e. hydrogen is a gas at room temperature. For mobile and in many cases also for stationary applications the volumetric and gravimetric density of hydrogen in a storage system is crucial. Hydrogen can be stored by six different methods and phenomena: high pressure gas cylinders (up to 800 bar), liquid hydrogen in cryogenic tanks (at 21 K), adsorbed hydrogen on materials with a large specific surface area (at T < 100 K), absorbed on interstitial sites in a host metal (at ambient pressure and temperature), chemically bond in covalent and ionic compounds (at ambient pressure), oxidation of reactive metals e.g. Li, Na, Mg, Al, Zn with water. These metals easily react with water to the corresponding hydroxide and liberate the hydrogen from the water. Finally, the metal hydroxides can be thermally reduced to the metals in a solar furnace.     

多级A/O工艺在国内的应用现状

多级A/O工艺目前在国内市政和部分工业污水处理领域应用较多,具有预处理和污泥处理系统简单,污泥负荷低、处理效果好且稳定,投资低,曝气系统效率高、运行成本较低,维护管理简便等特点,但是在实际运行中也发现存在一些问题,如土池结构不适合地下水位高的地区的局限性,沉淀池效果较差、稳定池多余占地且污泥淤积难以清除,关键设备国产质量有待提高,工业污水处理少数水质指标偏高,需要设计人员选择适合其条件的场合应用,并进一步总结、改进和完善.
