But the clouds have affected the quality of remote sensing data, how to effectively use the modern computer science and technology to remove the cloud is a hot issue in the field. From the theory of cloud formation in the remote sensing image, we analyze the formation mechanism, and based on this we do two layers decomposition and reconstruct the structure according to wavelet transform in network communication, and establish the image degradation model. Combining Fourier transformation, we set up the removing cloud fusion model of remote sensing image. Through the simulation experiment, the effect is significant. To a certain extent, it provides technical support for theory study and practice operation.

Abstract: In marine organisms the carbon sink function of shellfish moves in circles. It not only has a great influence on the marine environment, also has the very important significance for the construction of marine ranching to realize the benefits of recycling economy. If the carbon consumption exceeds marine soil and Photosynthesis Carbon input, the marine environment will be subject to different degrees damage, and affect the marine farming production process. Based on this, this paper analyses and studies the shellfish and algae carbon sink function. The first part of this paper introduces shellfish and algae carbon sink regulation function, gives the schematic diagram of carbon cycle, and establishes a column chart through using the preliminary statistical data. The second part establishes the shellfish and algae carbon sink ecological economic system mathematical model in the construction of marine ranching, and gives the adjustment function diagram of ecosystems two coordination function. The third part uses the professional statistical analysis software SAS to draw the shellfish and algae carbon curve of marine ranching construction, which provides theoretical reference for considering the carbon sink function of marine ranching construction.

Abstract: In the thermal stability analysis of electronic equipment, usually we obtain the temperature by quasi circuit method and analytic method. Quasi circuit method is to use the method of circuit analysis, and the heat flux in electronic equipment is simulated into current value in short circuit analysis. The temperature is simulated into a voltage of the circuit. The values of conductance and resistance are simulated into some other valued of circuit components. Analytical method is set space function subordinate relationship value of temperature in electronic equipment. Usually these two methods are desirable, but in the actual design, due to the large computational quantity of quasi circuit method and analytic method, the calculation is complex. Therefore, we combine these methods to solve some traditional disadvantages using micro unit heat balance method, which provides a new method for optimal portfolio.
