乘积季节模型在能源生产量预测中的应用

本文使用乘积季节模型,对1999年到2005年全国能源生产总量进行分析,给出乘积季节模型的一般建模程序。根据Box-Jenkins的建模思想,从各种指标最终确定模型(0,1,1)×(0,1,1)12,该模型显示了非常好的拟合及预测效果。     

Ni-Doped BiVO4 with V4+ Species and Oxygen Vacancies for Efficient Photoelectrochemical Water Splitting

Bismuth vanadate is a promising photoanode material for photoelectrochemical(PEC)water splitting,but its activity and stability need to be further improved.In this work,we synthesized Ni-doped BiVO _(4 )abundant with V ~(4+)species and oxygen defects through an in situ electrodeposition method.The effective doping can decrease the particle size of BiVO _(4 )and lead to the formation of V ~(4+)species/oxygen defects.Accordingly,the doped and defective BiVO _(4 )showed high optical absorption and rapid charge transfer,and further showed much higher PEC activity than pure BiVO _4.Specifically,5-Ni-BiVO _(4 )exhibits the highest activity in PEC water splitting,with a photocurrent of 2.39 mA/cm ~(2 )at 1.23 V versus RHE(the reversible hydrogen electrode),which is 2.5 times higher than pure BiVO _4(0.94 m A/cm ~2),and much higher incident photon-to-current efficiency(IPCE)value of 45%(while only 25%for BiVO _(4 )at ca.400 nm).This work provides an in situ method for the development of a high-performance photoanode.

Effect of Flow Directions on Multiphase Flow Boiling Heat Transfer Enhanced by Suspending Particles in a Circulating Evaporation System

A circulating fluidized bed evaporator(including down-flow, horizontal, and up-flow beds) was constructed to study the effect of flow directions on multiphase flow boiling heat transfer. A range of experimental investigations were carried out by varying amount of added particles(0-2%), circulation flow rate(2.15-5.16 m~3/h) and heat flux(8-16 kW/m~2). The comparison of heat transfer performance in different vertical heights of the horizontal bed was also discussed. Results reveal that the glass bead particle can enhance heat transfer compared with vapor-liquid two-phase flow for all beds. At a low heat flux(q = 8 kW/m), the heat-transfer-enhancing factor of the horizontal bed is obviously greater than those of the up-flow and down-flow beds. With the increase in the amount of added particles, the heat-transfer-enhancing factors of the up-flow and down-flow beds increase, whereas that of the horizontal bed initially increases and then decreases. However, at a high heat flux(q=16 kW/m), the heat-transfer-enhancing factors of the three beds show an increasing tendency with the increase in the amount of added particles and become closer than those at a low heat flux. For all beds, the heat-transfer-enhancing factor generally increases with the circulation flow rate but decreases with the increase in heat flux.     

日本国立大学法人化改革中的人事制度改革

日本在2000年对国立大学的法人化改革进行了调查研究，并于2002年出台了最终报告。日本国立大学法人化改革中的人事制度改革，如职员身份定为“非公务员型”；校长的选拔由选拔委员会进行，听取社会各方面的意见；教师可以兼职、兼业等，都对我国高校人事制度改革具有一定的启示。
