1COMPUTATIONAL SCHEME FOR SIMULATING PLASMA DYNAM-ICS DURING PLASMA-IMMERSION ION IMPLANTATION显示文摘Plasma-immersion ion implantation (PIII) is a technique for implanting ions into conducting, semiconducting and insulating objects. In PIII, the object being treated is immersed in a plasma and pulsed to a large negative voltage (=-1 to-100 kV). The resulting sheath expands into the ambient plasma, extracting ions and accelerating them to the target. PIII has advantages over beam-line implantation in that large surfaces can be rapidly implanted, irregularly-shaped objects can be implanted without target manipulation, and surfaces that are not line-of-sight accessible can be treated. A two-dimensional, self-consistent model of plasma dynamics appropriate for PIII is described. The model is a hybrid, with Boltzmann electrons and kinetic ions, where the ion Vlasov equation is solved using the particle-in-cell (PIC) method. Solutions of the model give the time dependence of the ion flux, energy and impact angle at the target surface, together with the evolution of the sheath.T. E.

2Validity of the Bouchet's complementary relationship at 102 observatories across China显示文摘Bouchet in 1963 hypothesized that for large homogeneous land surface with minimum advection of heat and moisture,there exists a 1:1 complementary relationship of potential and actual evaporation coupled through land-atmosphere feedbacks.The complementary relationship has been widely used to estimate regional actual evaporation and explain the pan evaporation paradox.We examine the standardized potential evaporation(potential evaporation divided by wet environment evaporation) at 102 observatories at different elevations across China.Generally,the relationship is appropriate at the low elevations(<1000 m).With the increase of elevation,vapor transfer power becomes much less than radiation energy budget because of lower vapor pressure deficit and stronger global solar radiation.As a result,at the high elevations(over 1000 m),the excess energy resulted by limited moisture availability is not enough to be converted into drying power of the air.This result suggests that the complementary relationship is asymmetric at the high elevations.YU JingJie1,2,ZHANG YongQiang3,LIU ChangMing1,2 1 Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences,Beijing 100101,China 2 Key Laboratory of Water Cycle and Related Land Surface Processes,Chinese Academy of Sciences,Beijing 100101,China 3 CSIRO Land and Water,PO Box 1666,Canberra ACT 2601,Australia 2009Science China Earth Sciences2009,52,5:2
3ON FORMATION OF TIDAL FRONTS IN COASTAL SEAS显示文摘An energy equation which includes the effects of potential energy,turbu-lent dissipation,heat flux and density flux due to fresh water discharge from estuaries isderived to evaluate the formation of frontal structures in coastal seas.Two different formsof tidal mixing criteria emerge which are the h/u^3 of Simoson and Hunter(1974)for openshallow water and the h/u of Nunes et al(1989)for estuaries.The theory is capable of predictiong tidal fronts in areas where both surface and lateral input of buoyancy are signifi-cant.The theory is applied to a tidal estuary and the locations of haline fronts which resultfrom the influence of the fresh water discharge are predicted.The effect of surface heatingon the formation and location of the frontal system is also discussed for the estuary.Wang Xiao-huaDepartment of Geography and Oceanography, University College, Australian Defence ForceAcademy, Canberra ACT 2600, Australia, Email :h-wang @ adfa.oz. auM.

20Do Search and Selection Operators Play Important Roles in Multi-Objective Evolutionary Algorithms:A Case Study显示文摘Multi-objective Evolutionary Algorithm (MOEA) is becoming a hot research area and quite a few aspects of MOEAs have been studied and discussed. However there are still few literatures discussing the roles of search and selection operators in MOEAs. This paper studied their roles by solving a case of discrete Multi-objective Optimization Problem (MOP): Multi-objective TSP with a new MOEA. In the new MOEA, We adopt an efficient search operator, which has the properties of both crossover and mutation, to generate the new individuals and chose two selection operators: Family Competition and Population Competition with probabilities to realize selection. The simulation experiments showed that this new MOEA could get good uniform solutions representing the Pareto Front and outperformed SPEA in almost every simulation run on this problem. Furthermore, we analyzed its convergence property using finite Markov chain and proved that it could converge to Pareto Front with probability 1. We also find that theYan Zhen-yu, Kang Li-shan, Lin Guang-ming ,He MeiState Key Laboratory of Software Engineering, Wuhan University, Wuhan 430072, Hubei, ChinaSchool of Computer Science, UC, UNSW Australian Defence Force Academy, Northcott Drive, Canberra, ACT 2600 AustraliaCapital Bridge Securities Co. ,Ltd, Floor 42, Jinmao Tower, Shanghai 200030, China 2003Wuhan University Journal of Natural Sciences2003,8,S1:1
