In view of the shortcoming of conventional CMOS current multiplier/divider in low linearity and low frequency,a novel CMOS current modemultiplier/divider based on MOS Translinear rule,with square-root and squarer/divider circuit for core circuit,is proposed.HSPICE simulation test using TSMC's0.35 μm CMOS process model show a -3 dB bandwidth of 35.1 MHz for the circuit,working at a supply voltage of 3 V,and its static power consumption is 202.68 μW,output current range 0~25.1 μA,nonlinear error 0.85% and total harmonicdistortion 0.14%.Compared with the multipliers/dividers designed by Tanno,Lopez,et al.,the proposed multiplier/divider circuit has many advantages,using-3 dB bandwidth,reduced power consumption,reduced power supply voltage,improvedlinearity,raised accuracy,and a relatively more advanced 0.35 μm CMOS technology,and saving chip area.

Based on the Solar wind-Magnetosphere-Ionosphere coupling global MHD simulation,the position and shape of the noon midnight meridian plane magnetopause under several solar wind dynamic pressure and interplanetary magnetic field (IMF) conditions are studied.The simulation results show that,in the noon midnight meridian,plane magnetopause shape has a concave structure.And at certain D_p,when southern IMF B_z (B_z＜0) increases,the subsolar position (r₀) of the magnetopause decreases and when northward (B_z＞0)increases,the subsolar position r₀ keeps gradually increasing.Significant decreasing of r₀ appears with the increase of D_p.For all casesstudied,the flare angle (z₀/x₀) of the magnetopause increases when (B_z＜0)increases.These simulation results are consistent with the empirical results basedon satellite data in high-latitude empirical model (B00) and (Schield) model.That is to say,MHD simulation is an effective tool to study the magnetopause shape.It is an effective way,based on the configuration of physical theory on magnetopause numerical simulation data,to solve the problem that relates to the obtaining of transversing data in high latitudes being limited.

Attribute reduction is the core issue in the rough set theory,so it's urgent to delete irrelevant or inconsequential attributes rapidly andeffectively in current research.To deal with this problem,this paper proposes an algorithm of attribute reduction based on GEP.This method has the advantage ofquick convergence and the capacity to avoid easy entrapment at local optimum.Experiments show that this algorithm can generate the smallest reduction quickly and efficiently.

Continuousand real time playbacks are important QoS requirements for streaming media application and there should be a balance between the two factors.An effective balancealgorithm named PBB is proposed.In PBB,each receiving end host has an adaptive bufferin order to reduce delay jitter.In addition,a given controller is adopted to modulate the size of buffer so that unacceptable end-to-end delay is avoided.At last,the simulation evaluation gives the comparison between PBB and classic algorithms.The results show that PBB can achieve a good balance between continuous and real time playbacks.

Winter habitat selection of one group of Macaca mulatta was investigated from November,2009 to February,2010 in Gehuaqing region in Baimaxueshan National Nature Reserve,Yunnan province,China.Fourteen ecological factors were measured in 60 plots (20 m×20 m) where the study group everstayed.These factors included canopy cover,topographic feature,elevation,slope aspect,slope degree,vegetation type,the distance to water,human disturbance,numbersof trees,dead wood,cutting trees,DBH (diameter of breast height of tree),fruitabundance on the ground.The analysis indicated that in winter,M.mulatta tended to stay at elevations ranging from 2 500 m to 3 200 m,and selected the 20°～40° mountain slope with 60%～100% canopy cover.M.mulatta preferred evergreen broadleaf forests,where there were more trees with DBH＞20 cm.They tended to stay in the forests far from human disturbance (＞500 m),and close to water resource.

In recent decades,zero emissionsfermentation bed technology has been used to solve the excreta of pig from polluting theenvironment in pig industry at home and abroad.But,in application,there exist many problems,such as,high temperature of the fermentation bed,high cost and the production of harmful gas.By combining the advantages and disadvantages of the fermentation bed raising pig method with cement floorraising pig method,this paper devise a new raising-pig method—thin mat fermentation bed method,which is more suitable for the south areas.Compared with the former pig feeding mode in the following aspects,such as:costs of mat,incidence ofdisease,slaughtering rate,water consumption,growth increment in weight,feed amount and the feed/gain ratio,the results show that the new method is more environmental friendly in saving labor,provincial medicine and water,which is anecological raising-pig method of low cost,low emission and no smell.

The effects of mixed low-molecular-weight-organic-acids (LMWOAs,acetic acid,formic acid,malic acid and citric acid) on the absorption of Cd and Zn of rape were studied in contaminated soil through pot experiments.The results showed that with the increasing amount of LMWOAs,the amounts ofCd and Zn in rape shoot exhibited complex changes.LMWOAs could increase the amounts of Cd and Zn in B1 and B2 fractions of rhizosphere soil (except Cd in B1 fractions),however,LMWOAs had little effect on Cd and Zn in nonrhizosphere soils.Underthe stress condition of Cd or Zn,low concentration of LMWOAs could decrease the toxicity of Cd or Zn and increase the biomass of rape.However,high concentration of LMWOAs could increase the amount of Cd or Zn in B1 and B2 fractions of rhizospheresoil,increase the toxicity of Cd or Zn,so as to restrain the growth of rape.

Taking Guilin city as an example,three kinds of vegetation Index (NDVI、RVI、TNDVI) are extracted and the LST was calculated by inversionbased on TM images.This paper analyzes the statistical characteristics ofvarious parameters from different types of land use and the city space,and discusses quantitatively the linear relationship between vegetation Index and LST.Theresults show that Forest land,farmland and city suburbs have higher vegetationIndex,the built-up with more proportion of Impervious layer has higher surfacetemperature,vegetation Index and LST have a significant negative correlation.Compared with suburban,the changes of ground characteristics and low vegetation coverage contribute most to the urban heat-island effect in urban built-up areas.
