This approach is found to be effective in driving the desired rate of tumor cell kill and converging the system to healthy equilibrium state.

文摘The development mode of mid-small cities in northern Jiangsu is analyzed on the Growth Pole theory.Depending on scales,endowment of resources,geographical positions,and industrial advantages of mil-small cities,we can divide the development mode of those mid-small cities within this context into five types:development through integration into big cities;independent development;resource-dependent development;single industry development;and mixed industry development.
