Based on of nonmomental theory of axial symmetry revolving shell, it is discussed specially on tactic’s analysis of global coping of large-scale anaerobic digester.

The boundedness of the set of infinite matrix transformations from convergence-free space to sequence spaces is studied,and a general form of it is deducted.

Let λ and μ be sequence space and have both the signed-weak gliding hump property,(λ,μ) be the algebra of the infinite matrix operators which transform λ to μ.

This paper introduces the research development of the important effect algebra in quantum mechanics,and points out that it is of great significance to the establishment of mathematical foundation of quantum mechanics by making use of infinite matrix theory to study its convergent theory and invariants.

According to the reactive torque,the stator flux linkage is adjusted as the supplement of the exc.
