The amount of sales un-house is important basis for inventory management of commerce enterprises. Through carefully analyzing about previous researching results, we find that tradition forecasting methods, such as time series analysis, regression analysis, Kalman filtering and the predictions of neural networks, have some defects in large information demanding, the numerical instability and insensibility to environment changes. So, based on GM (1, 1) model and combining calamity grey prediction at residual hour, this paper establishes a REM-GM (1, 1) model and with the aid of cluster prediction method successfully forecasts the amount of sales un-house of commerce enterprises. The empirical studies observe that the model of un-house forecasting, no matter whether one step forecast or multi-step long time forecast, has a more remarkable prediction precision.

By using the perturbation theories on sums of ranges of nonlinear accretive mappings of Calvert and Gupta, we study the abstract results on the existence of a solution u ∈ L^s （Ω） of nonlinear boundary value problems involving the p-Laplacian operator, where 2≤ s〈＋∞, and 2N/N＋1 〈 p ≤ 2 for N（≥ 1） which denotes the dimension of R^N. To obtain the result, some new techniques are used in this paper. The equation discussed in this paper and our methods here are extension and complement to the corresponding results of L. Wei and Z. He.

Based on the measuring data and Digital Elevation Data (DEM) in a typical watershed--Hemingguan Watershed, Nanbu County, Sichuan Province of China, a GIS-based distributed soil erosion model was developed particularly for the purple soil type. It takes 20 m × 20 m grid as calculating unit and operates at 10-minute time interval. The required input data to the model include DEM, soil, land use, and time-series of precipitation and evaporation loss. The model enables one to estimate runoff, erosion and sediment yield for each grid cell and route the flow along its flow path to the watershed outlet. Furthermore, the model is capable of calculating the total runoff; erosion and sediment yield for the entire watershed by recursion algorithm. The validation of the model demonstrated that it could quantitatively simulate the spatial distribution of hydrological variables in a watershed, such as runoff, vegetation entrapment, soil erosion, the degree of soil and water loss. Moreover, it can evaluate the effect of land use change on the runoff generation and soil erosion with an accuracy of 80% and 75% respectively. The application of this model to a neighboring watershed with similar conditions indicates that this distributed model could be extended to other similar regions in China.

孔子的仁学思想折射了实践理性的基本特质,它构成了中华法系的理性基础,这使得中华法系表现出合规律性、合目的性和审美合理性的总体特征。孔子的中庸理念是中华法系思维方式的思想基础,中庸作为一种实践之知对混合法之法律样式、中华法系的道德化和情理化都产生了重要的影响,它有效地抵制了中华法系向绝对主义发展的可能性。正是由于孔子思想的实践理性和实践智慧的特质,才可能对孔子的思想进行实践法哲学的当代阐释,而这种阐释构成了理解中华法系的崭新视角。
