Based on a lot of empirical analysis, the author summerizes that the historical premises of mergers in the United States include of the development of modern-enterprise、the technical innovation、the expansile demand and the development of capital market, surveys the developments and characters of mergers in the United States. From Marx's capital concentration theory to the arguments between structure school and conduct school, from the theories of economists at the present age abroad to the achievements of the learned men in China. the author surveys the theorical developments of merger. Making a clear definition of the concept and premises of self-organizational merger on the hypothesis that enterprise is a kind of self-organization, futhermore, the author constructs the theoretical frame of self-organizational merger.

A conspiracy theory is the belief and empirical hypothesis that historical or current events are the result of manipulations by one or more secretive powers or conspiracies Because conspiracy theories are frequently difficult to support with evidence, they are used as derogatory words According to Karl Popper's philosophy of science and falsifiability criteria, conspiracy is not a science But in reality, conspiracy theories are not all baseless, irrational and deceptive

阴谋理论是一种信仰，也是一种经验假设，认定某些事件是由一个或几个有势力的秘密组织阴谋操控、秘密实施产生的结果。由于阴谋理论往往很难得到事实的佐证，因此成为一个贬义用语。按照波普的科学哲学观与检验理论科学性的标准，阴谋理论并非科学。但事实上，阴谋理论并非是无根据的、非理性的、虚伪的。

The main contents of this dissertation are as follows:(1) According to involved theories of ferromagnetics, the microscopic mechanism of domain structure is analyzed systematically; through the movement variation of domain structure, that is the movement of domain wall and rotation of magnetic moment, the magnetization process is illustrated in an applied magnetic field. Meanwhile, by the use of energy methods, a study is performed on influencing factors of domain movement including stress, dope, scattering field, etc. The influence of various energies is dealt with on the magnetic behavior and parameters of ferromagnetic material; the corresponding theories of the spontaneous magnetization and technical magnetization are also discussed.

From the perspective of minimum transmission losses, an instantaneous reactive power theory for systems with any number of phases and with or without neutral line is developed. Under the new definition, each quantity has its own physical meaning, and the zero sequence current can be decomposed into active and reactive components. Furthermore, a generalized compensation method for zero sequence current is developed.
