MnO 2 /polyaniline/graphene composite as a supercapacitor electrode material was synthesized through an interfacial polymerization approach in the interface of oil/water phase. The as‐synthesized MPG is characterized by infrared spectroscopy, XRD, XPS, SEM and TEM, and its electrochemical performance is measured by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy. The 3D nanostructure of MPG and loose nanorod structure of polyaniline (PANI) coated with round MnO 2 pellets could be clearly observed. The maximum energy density of MPG is 45.4 Wh/kg (at a power density of 67.8 kW/kg) and the highest power density is 229.2 kW/kg (at an energy density of 25.7 Wh/kg). The capacitance retentions after 500 cycles at the scan rate of 5 mV/s for MGP composite and PANI/graphene are 70.4% and 59.1%, respectively, and the capacitance values after 500 cycles are 158.4 F/g and 114.8 F/g, respectively. The improved performance of MPG is due to the 3D nanostructure, loose nanorod structure of PANI and stable support of graphene, which prevent the mechanical deformation effectively during the fast charge/discharge process and facilitate the diffusion of the electrolyte ions into the inner region of active materials. The composite material is very promising for the next generation of high‐performance supercapacitors electrode.

Comparison and validation of canopy reflectance(CR)models are two important steps to ensure their *** forest plantations are an ideal type of forest for validating CR models because of their simple background and the low variance in the crown structures which are usually assumed to be identical in most CR models.A Geometric Optical Model for Forest Plantations(GOFP)was compared using dataset in two radiation transfer model intercomparison exercise(RAMI)stands and validated using in situ dataset of detailed optical and structural data of two forest plantations in the Saihanba Forestry Center,*** results show that(1)the tree distributions in stands described by the hypergeometric model in GOFP show good consistencies with the dataset in the two RAMI stands and measurements from the two Saihanba forest stands;and(2)the CRs simulated with GOFP are also compared well in the two RAMI stands and validated with measurements collected with unmanned aerial vehicles in the two Saihanba *** shows a better consistency with the CR measurements than those from CR models for natual forestsbecause the tree distribution in forest plantations is described more reasonably in GOFP.

冠层间隙率和叶片聚集度指数对植被拦截光和冠层辐射传输过程有重要影响。叶片往往以树冠的形式聚集在森林中,而树冠在诸多森林冠层几何光学模型中有重要作用。之前的研究主要集中于树冠的形状(例如圆柱、圆锥、椭球、圆锥+圆柱等)特征对冠层间隙率和叶片聚集度的影响。然而,树冠的结构特征除了包括形状特征外,还包括尺寸特征。事实上,树冠的尺寸特征是植被在长期进化过程中与自然环境相互作用的结果,且比树冠形状特征具有更明显的地理空间特征。本文首先修改了前人常用的用于描述树冠分布的泊松分布模型,其次,利用超几何模型更为真实地、定量地描述树冠之间的排斥效应和树冠的分布情况;最后,以椭球树冠为例,设定了从"瘦高"型到"矮胖"型等7种尺寸的树冠,分别通过固定树冠半径和树冠体积两种途径探讨了树冠尺寸特征对冠层间隙率和叶片聚集度的影响。结果表明:(1)无论固定树冠半径,还是固定树冠体积,树冠尺寸特征对冠层间隙率和叶片聚集度指数的影响,均比树冠形状特征对间隙率和叶片聚集度指数的影响明显;(2)树冠的尺寸对冠层间隙率和叶片聚集度的影响非常显著,且具有明显的规律性。树冠在观测方向的投影面积越大,冠层间隙率越小,叶片聚集指数度越大,冠层内叶片越趋于泊松分布。

森林地上生物量(AGB)是评价森林生态系统功能的重要参数,遥感是获取区域尺度AGB的有效手段。以内蒙古根河市为研究区,利用TM遥感影像数据和33个森林样地调查数据,基于四尺度几何光学模型的森林AGB遥感估算方法,首先,基于样地观测数据建立树冠面积(SA)估算AGB的方程;再利用四尺度几何光学模型建立由冠层反射率反演SA的查找表,由TM影像反演SA,进而估算AGB。在全部33个样地,估算的AGB与观测数据的一致性(RMSE=20.8t·hm-2,R2=0.45)明显优于基于差值植被指数(DVI)(RMSE=27.7t·hm-2,R2=0.09)和混合像元分解(SMA)(RMSE=27.6t·hm-2,R2=0.02)方法建立的统计模型的估算结果。利用19个针叶林样地的观测数据验证表明,估算的AGB的RMSE和R2分别为20.8t·hm-2和0.53,利用DVI估算的AGB的RMSE和R2分别为31.5t·hm-2和0.18,利用SMA方法估算的AGB的RMSE和R2分别为31.8t·hm-2和0.14;对于14个阔叶林样地,估算的AGB的RMSE和R2分别为20.9t·hm-2和0.47,利用DVI估算的AGB的RMSE和R2分别为21.4t·hm-2和0.01,利用SMA方法估算的AGB的RMSE和R2分别为20.6t·hm-2和0.11。结果表明:通过反演与AGB紧密联系的SA,进行AGB的遥感估算是一种有效可行的技术方法。

针对Φ785 mm立式连铸大圆坯,建立了流动、传热、凝固、传质三维耦合模型。通过该模型预测了从弯月面到完全凝固范围内铸坯溶质元素的分布情况,研究了大圆坯宏观偏析形成过程。模拟结果表明:连铸前期钢液对凝固前沿的溶质冲刷效应是铸坯表面区域出现明显负偏析带的主要原因;随着钢液的不断凝固,铸坯中心区域残余液相的溶质元素不断富集,最终导致了中心偏析的产生,C元素中心最大正偏析指数为1.08;另外,不同溶质元素宏观偏析严重程度有所不同,但呈现出的分布趋势基本相同。
