查询词典 theory model

The formation mechanism of the absolute instability and gyrotron backward wave oscillations is analyzed, and the methods to suppress the parasitical modes are discussed.The nonlinear theory model of gyro-TWT is consummated by considering the influence of tapered magnetic field and waveguide radius, electron velocity spread, and waveguide loss on electron beam-wave interaction. The large-signal characteristic of gyro-TWT, such as launching loss and absolute instability, are also analyzed in detail. This work establishes the foundation for the development of a gyro-TWT amplifier.

从目前国内外在构造反演这一问题的研究现状来看，在拉张构造区域，反演问题在理论上有比较多的模拟解决办法，并且应用的相当成功，不过考虑到有些特殊的情况，比如逆牵引构造所派生的次级断裂会造成反演计算结果的不准确，因此对现存的反演模型稍微做出了点修改，使之更能广泛的应用于实际的构造解释。
