In this paper, we investigate the growth of transcendental entire solutionsof the following algebraic differential equation a(z)f'~2 +(b_2(z)f^2 +b_1(z)f +b_0(z))f'=d_3(z)f^3+d_2(z)f^2 +d_1(z)f +d_0(z), where ...In this paper, we investigate the growth of transcendental entire solutionsof the following algebraic differential equation a(z)f'~2 +(b_2(z)f^2 +b_1(z)f +b_0(z))f'=d_3(z)f^3+d_2(z)f^2 +d_1(z)f +d_0(z), where a(z), b_i(z) (0<- i <=2) and d_j (z) (0<=j<= 3) are allpolynomials, and this equation relates closely to the following well-known algebraic differentialequation C(z,w)w'~2 + B(z,w)w' + A(z,w) =0, where G(z,w)not ident to 0, B(z,w) and A(z,w) are threepolynomials in z and w. We give relationships between the growth of entire solutions and the degreesof the above three polynomials in detail.展开更多

Through field surveys and inductive analyses, analyzing of the content of upgrading the coal industry as an entry point, this paper analyzes the sustainable development mechanisms for the coal industry from the aspects of work force, power, methods, goals, and so on; and puts forward corresponding developmental modes according to the mechanisms which can improve resource recovery and mineral resources utilization rates by putting them into practice.展开更多

To change the present development model, the spatial distribution of industries must coordinate with the environmental bearing capacity. The present practice we take to change resources distribution to meet the existing arrangement of industries will bring incredible calamitous consequence to the development in the future. To make industry’s arrangement coordinate with ecological environment, and to adopt the method similar to “arranging along the rivers” should become the guidelines of spatial distribution of industries.展开更多

However, their growth patterns are obsolete, impeding the quality and competitiveness of their economic growth, while simultaneously threatening the sustainability of their economic convergence with developed nations. Transforming the domestic growth pattern-the solution to the middle-income trap-has therefore become a key priority for each of these economies. This paper presents a comparative analysis of how to transform the pattern of economic growth in BRICS and achieve sustainable economic convergence with a comparative analysis of the pattern of economic growth and problems among BRICS countries.展开更多

Relatively, there must be certain basic conditions. This article makes elaboration of the basic conditions, which accelerate the change of Shaanxi＇s economic growth mode from government angle, and proposes countermeasures for it, according to Shaanxi＇s situation and the requirement of scientific development concept, in order to provide basis for the government＇s economic growth transformation.展开更多
