A NEW MODEL FOR WIDEBAND GENERATION IN A GYRO-TWT AMPLIFIER增加回旋行波放大器带宽的一种新方法回旋行波放大器带宽增益提出了一种增加回旋行波放大器带宽的新模型,其特点是适当地选取轴向引导磁场的初值并从相互作用区的给定位置开始使其缓慢地线性减小.该模型的输出带宽可达到已有宽带模型的水平,但效率有较大提高...
The oxygen atoms belonging to the biaryl ether group and the carbonyl group are involved in those forms; the planar tricyclic system, associated with a zwitterionic form, contributes for the poor solubility of the xanthone itself, which can be changed by adding substituents, concurring to higher ...
