According to the discussion of the development course and the current situation of the air pollution treatment technologies in China, the choke point of the research and development (R&D) pattern for air pollution treatment technologies is analyzed and a new technology development pattern is founded. The core of the pattern is multi-scales and system class simulation. The key point experiments and engineering regression are used as assistant instruments. This new pattern is successfully used to develop the flue gas desulfurization and denitrification technology for high capacity power plants. And the technology has already realized the large-scale application. Using this pattern, a new technology can be finally developed and made it maturity in a short period.
