界壳论进展（Progress in the theory of bounded shells） Progress in the theory of bounded shells ________________________________________ Earth (1) outline of the theory of bounded shell The shell phenomenon is widespread in nature and in human societies, such as egg shells, the earths atmosphere, human clothing, biofilms, borders, and so on. It can be said that no matter where, regardless of work or study, will encounter problems such as shell theory. In biology, shell phenomenon is the most representative, such as turtle or turtle with a thick shell to protect themselves. The periphery of the cell membrane is the shell phenomenon at the molecular level in addition to the protection of cell membrane; extracellular ion channels in the membrane. These channels from a single molecule or molecular complex composition, can allow ions to pass through. The opening or closing of an ion channel affects cell life and cell function in normal or pathological states. In the social and economic fields, the phenomenon of shell is also everywhere. The most typical is the European castle and Chinese to protect walls, rulers and subjects. A country or region has boundaries or boundaries, and only through customs can people and goods be allowed to come in and out. In the economic field, as in Japan, the employment tenure system prevails, that is, when a person is young, once he enters an enterprise, he is always surrounded by the big wall of the enterprise, and there is little communication.. Today, protectionism is another form of shell in all parts of the world. Each area of their respective shell formed in a cocoon around oneself, and hinder competition and exchange. If the system has a perimeter: Keep the system itself? Between system and environment It is called boundary hull. The shell theory is a general theory of system boundary, use some common rules that exist in the system of perimeter and its application in information, control, management, environment, biology, psychology, aesth
