A preliminary field-based investigation was undertaken in a small(<10 km^(2))river valley located in the mountainous Jura region of northwest *** aims of the work were to assess sediment generation and annual sediment transport rates by tree throw on forested hillslopes,and to document surface hydrology characteristics on four fresh soil mounds associated with recent tree throws over a 24-day monitoring *** the soil mounds,average sediment recovery ranged from 7.7-28.2 g(dry weight),equivalent to a suspended sediment concentration of 145.2-327.8 g L^(-1),and runoff coefficients ranged from 1.0%-4.2%.Based on a soil bulk density value of 1,044 kg m^(-3),upslope runoff generation areas were denuded by an average 0.14 mm by the end of the 24-day monitoring period,representing an erosion rate equivalent to 2.1 mm yr^(-1).A ca.50 cm high soil mound could therefore feasibly persist for around 200-250 *** tree throw work,the dimensions of 215 individual tree throws were measured and their locations mapped in 12 separate locations along the river valley representing a cumulative area equivalent to 5.3 ha(***,43 per ha).Tree throws generated a total of 20.1 m^(3) of fine-sediment(<2 mm diameter),or the equivalent of 3.8×10^(-4) m^(3) m^(-2).The process of tree throw was originally attributed to two extreme weather events that occurred in west and central Europe in late December *** the 18-year period since both storms,this represents an annual sediment transport rate of 2.7×10^(-5) m^(3) m^(-1) yr^(-1).Exploring the relationship with wind on fall direction,65.5%of tree throws(143)generally fell in a downslope direction irrespective of hillslope aspect on which they were *** infers that individual storms may not have been responsible for the majority of tree throws,but instead,could be associated with root *** the high density of tree throws and their relative maturity(average age 41 years),we hypothesise that once tr

超短激光技术的发展为研究材料中的超快光动方学过程提供了重要的实验手段,也使得人们能够更为深入地研究电子的自旋动力学行为.GaAs(100)表面由于费米钉扎而会导致能带弯曲,位于该区域的电子及其自旋特性将会明显不同于体相材料中的情况.利用时间分辨和自旋分辨的双光子光电子发射技术研究了p型掺杂GaAs(100)表面的电子极化动力学过程.结果表明,由费米钉扎而引起的能带弯曲明显影响电子的自旋弛豫过程,从实验上观察到了GaAs(100)表面能带弯曲区域的电子自旋翻转时间存在近2个量级的差异(从几纳秒到几十皮秒),基于电子_自旋交换相互作用的BAP机理在自旋弛豫过程中起着主导作用.

Journal of Energy and Power Engineering 2012年第1期6卷 132-139页

作者： jan Leuchter Pavel bauer Vladimir Rerucha Department of Electrical Engineering University of Defence Brno 66210 Czech Republic Electrical Power Processing Department Delft University of Technology Delft The Netherlands

The paper makes survey of operating principle of power management of photovoltaic system with supercapacitors and a maximum power tracker （MPT） control to achieve the maximum efficiency. Supercapacitors are well suited to replace classical batteries and conventional capacitors in photovoltaic applications to improve a dynamic behaviors and life-time. It describes the advantages of a supercapacitors solution and shows the results of comparison with convenient batteries. The paper presents different topologies of basic photovoltaic concepts with dc-dc converters and supercapacitors according to the power dimension. The mathematical equations describing the photovoltaic cells, temperature analyses and mathematical solution of MPT are shown in the paper and supported by measurements. The mathematical models were applied in the design of 50 W and 6 kW photovoltaic sources with MPT and supercapacitors. Both models were verified using experimental measurements on the photovoltaic setup.

作者： jan Leuchter Pavol bauer Department of Electrical Engineering University of De fence Brno 66210 Czech Republic Electrical Power Processing Department Delft University of Technology Delft The Netherlands

The paper makes survey of power electronics of hybrid power sources. These power supply units are based on the EGS (engine-generator set), photovoltaic systems with MPPT (maximum power point tracker), fuel-cell power sources will be discussed. The recent trends lead to the use of more autonomous power sources to satisfy the maximum energy yield. These power units can be considered as comparatively sophisticated system, consisting of mechanical part, electromechanical energy conversion part, power electronics and control (feed-back) part. These systems usually request a power buffer with battery and bi-directional dc-dc converter. The paper presents different topologies of dc-dc converters. Two aspects will be considered, namely power electronics converter concept with central boost converter design. This paper also briefly shows experimental verification of these modern power sources 6 kW.
