Adaptability of Polymer-Containing Sewage Corrosion Inhibitor  [PDF]
Limei Sun, Chunxi Gao, Wenmiao Gao, Jie Cui, Jianhua Xu
Journal of Materials Science and Chemical Engineering (MSCE) , 2018, DOI: 10.4236/msce.2018.67008
Abstract:
The polymer content in the produced water from Tuoliu Station is about 20 mg/L. Cationic imidazoline-type corrosion inhibitor is used to corrosion control of sewage. The corrosion inhibitor can react with the negatively charged materials such as anionic polymer and suspended substance by adsorption and merging to form complex aggregates, so that the suspended solids content increases, resulting in suspended solids content of exported sewage has been high. So a new type of non-ionic corrosion inhibitor has been developed and field trials have been performed. The results show that non-ionic corrosion inhibitor can effectively reduce the suspended solids content of wastewater while ensuring the corrosion rate of wastewater.

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.211025
Abstract: Accounting standards are integral components of economic policies; objectives of accounting standards reflect objectives of economic policies. Obviously, accounting standards play an indis-pensable role in promoting the orderly and stable development of the economy. This article expounds the relationship between different accounting standards and economic policies; accounting standards attribute and influence factors in the setting process of Chinese accounting standards. Under visual angle of public management, this essay analyses every relevant stakeholder’s influence degree and choice behavior in the setting process of accounting standards, especially the function and behavior of the government. The conclusion is that high-quality accounting standards can be formulated in the case of the government’s leading and other relevant stakeholder’s common participation. Only in this way can we work out the optimal accounting standards for Chinese situations.

Abstract: It is proved that in a regular boundary system of rectangular, cylindrical or spherical coordinate, an arbrtrary Vector function can be separated into three orthogonal parts: TE mode field, T-M mode field and irro'tational field. Each of these components can be determined fully by a scalas function. On the basis of this theorem, the compltenesa of vector wave function system {L, M, and N} is proved, also. Thus it is explained that a vector furc-tion space can be proiected into three uncrossed subspaces not only in Euclidean space but alsoin the subspace of vector wave functipn space.

Abstract: A new method for solving electromagnetic field boundary value problem is given. By using this method, the boundary value problem of vector wave equation can be transformed Into two independent boundary value problems of scalar wave equations and other two additional vector differentia! operations. All the dyadic Green's functions got by eigenfunction expansion of dyadic Green's functions can be got by this method easily and some of the dyadic Green's functions for complex system which are very difficult to get by ordinary method have been got by this new method. The dyadic Green's function for a dielectric loaded cavity is one of the given examples.

Abstract: The equation of electric field radiated by the current f electron beam in a waveguide with arbitrary cross-section is derived. In this equation, the ordinany dyadic Green s function is replaced by the modified one in which the eigenfield is normalized by the power flow. By this equation, the energy conservation in the radiation process can be proved. This equation can be used to compute the interaction of the actual electron devices.

Abstract: The energy conservauon in the radiation process by electron beam in a waveguide with arbitrary cross-section is proved. Some mistakes in Ref. 1] by myself are corrected. And the results are extended to the waveguide system with one shorted end. This result explains that the energy conservation is the intrinsic attributes of the Maxwell's equation set.

Abstract: The moment method based on the concepts of linear spaee can be applied not only to numerieal computation of the Electromagnetic field, but also to the analytic solution. By taking the eigenfunetions as basis functions and test funetions, a very simple, but generalized formula of the solution for the scalar wave equations and Poission s equations can be got. This formula not only can be applied to the scalar wave equations; but also can be applied to vector wave equations by some modifications.
Orthonormal Expansion l1-Minimization Algorithms for Compressed Sensing
Zai Yang,Cishen Zhang,Jun Deng,Wenmiao Lu
Mathematics , 2011, DOI: 10.1109/TSP.2011.2168216
Abstract: Compressed sensing aims at reconstructing sparse signals from significantly reduced number of samples, and a popular reconstruction approach is $\ell_1$-norm minimization. In this correspondence, a method called orthonormal expansion is presented to reformulate the basis pursuit problem for noiseless compressed sensing. Two algorithms are proposed based on convex optimization: one exactly solves the problem and the other is a relaxed version of the first one. The latter can be considered as a modified iterative soft thresholding algorithm and is easy to implement. Numerical simulation shows that, in dealing with noise-free measurements of sparse signals, the relaxed version is accurate, fast and competitive to the recent state-of-the-art algorithms. Its practical application is demonstrated in a more general case where signals of interest are approximately sparse and measurements are contaminated with noise.
