To sum up, the financial function of the public debt has widened the function of the public debt policy. The seigniorage function of public debt and the special function of public debt market in providing liquidity make public debt policy become more independent. Therefore, if public debt policy is to play a sufficient role in the macroeconomic management, it is essential to set up a developed and perfect public debt market.

From the function needing of the building, the top needs small axis dimension which has to be assigned, the next function part hopes that there is as big as possible free space, it is heavy for network to take post, for satisfying building the requests of function, the structure must be by fixing up contrary to routine way, in order to realize that this kind fixes up, must set up a special floor between the underpart in structure forms are different, make it bear top the internal force of structure and transmit and give underpart structure to play structure change the floors of function reliable. It is called transfer floor.

Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above. The experiment results indicate that the Turkey loss function based diffusion process can strengthen the conspicuous contour. Additionally, a Raita\'s criterion-based method, solving the automatic diffusion threshold, is proposed to automatically set the threshold in diffusion decomposition.
