A large-signal circuit model of QCL is described, which is based on a set of rate equations by analyzing the unipolar behavior of electrons in quantum well , and the frequency response characteristic of QCL is got by the circuit simulation of PSPICE Program. Consequently some factors that can affect the modulation characteristic of QCL have been analyzed .
The complexity and uncertainty of prediction on power supply and demand are analyzed in this paper, and studies the meta-synthesis method of man-computer integration from qualitative analysis to quantitative analysis. The meta-synthetic seminar hall system for power supply and demand research is designed and implemented. The system integrates power economy information, knowledge and experience of...
