摘要：
To Wuhan Metropolitan as an example,based on the conventional remote sensing data processing, aim at the data sources and regional characteristics, constitute the remote sensing data processing methods and processes that suitable for this area, then received the LUCC classified data of Wuhan Metropolitan. Carried out on the accuracy assessment of the Processing results The results show that, the general classification accuracy of Wuhan city circle three periods 1987,1996,2005 is 85.4%,85.04%,86.11% respectively, the total Kappa value is 0.7963,0.7805,0.8041 respectively. It is a high-accuracy process.

摘要：
This paper sets out to analyze the impact of financial crisis on the financial situation and the market share of small and medium-sized export enterprises. Then it moves on to study the causes of this problem from the perspective of the product structure of small and medium-sized export enterprises, regional structure, risk control and trading environment. Finally, suggestions and proposals are provided to address the financial crisis for the small and medium-sized export enterprises which include the upgrading of the product structure, the strategy of market diversification, and the improvement of enterprises' ability to resist risk and policy support.

摘要：
Let Omega be a bounded domain with a smooth C(2) boundary in R(N)(N >= 3), 0 is an element of (Omega) over bar, and n denote the unit outward normal to partial derivative Omega. We are concerned with the Neumann boundary problems: -div(vertical bar x vertical bar(alpha)vertical bar del u vertical bar(p-2)del u) = vertical bar x vertical bar(beta)u(p(alpha,beta)-1) - lambda vertical bar x vertical bar(gamma)u(p-1), u(x) > 0, x is an element of Omega, partial derivative u/partial derivative n = 0 on partial derivative Omega, where 1 < p < N and alpha < 0, beta < 0 such that p(alpha, beta) (sic) p(N+beta)/N-p+alpha > p, gamma > alpha-p. For various parameters alpha, beta or gamma, we establish certain existence results of the solutions in the case 0 is an element of Omega or 0 is an element of partial derivative Omega.
