Employing the self - consistent nonlinear theory , the wave beam interaction and the wave developing with time in the subnanosecond millimeter relativistic backward wave oscillator were theoretically analysised 本论文采用自洽非线性理论，理论分析了相对论返波振荡器中注波互作用及亚纳秒电子束与波在微波器件中随时间的演变过程。
Then the filter model is deduced to describe the intensity fluctuation induced by xpm in dispersion managed systems . according to this model , optimal dispersion management schemes are got 其次从理论上推导了在色散管理系统中由于交叉相位调制与色散互作用引起的脉冲强度起伏的滤波器模型，根据此模型得到了系统的优化色散补偿方案。
Design of a ship against explosion requires the theory of ship dynamic responses to the explosion . this is used to predict the structural damage , as well as the excitation of the foundation to the shipboard equipment concerned 流固相互作用效应对结构承受的载荷和结构的响应都有非常大的影响，是舰船水下爆炸动响应分析中的难点。
It has been shown in many experiments that by injecting plasma into the vacuum microwave devices , the interaction efficiency can be increased greatly , so that the output power can also be enhanced at the same input condition 等离子体填充后的cerenkov器件，在同样的输入条件下，互作用效率大大增加，从而输出功率也显著增加，这已为多个实验所证实。
And the simulation on the nonlinear beam - wave interaction of multi - cavity gyroklystron is made . the influences of more factors on efficiency and gain in multi - cavity gyroklystron are analyzed , comparing with in two - cavity gyroklystron 对34ghz三腔及四腔回旋速调管的注“波互作用进行了大量的数值模拟计算与研究，并与两腔回旋速调管进行了对比分析。
Due to applying double beams , the velocity spread is lower because of smaller influence of space charge compared with single beam mig . in the interaction region this beam is easy to start oscillation and reject mode competition effectively 与单注磁控注入枪相比,双注枪可以提供速度零散小、高束流的电子注,在互作用区更容易起振,且能更好的抑制模式竞争。
The main results are presented . second , the theoretical analysis about electron beam and wave interaction is presented . base on the theoretical analysis , numerical simulations of electron beam and wave interaction in gyroklystron were done 二、通过采用自洽非线性大信号理论方法,在理论分析和高频计算的基础上对回旋速调管放大器注-波互作用进行了数值计算。
At the same time the ionized electron under the strong laser field may return to the vicinity of the nucleus and recombine to the groud state . subsequently a photon of high energy may be emitted . this is high - order harmonic generation ( hhg ) 同时电离后的电子在强激光场的作用下，可能会回到核附近，与核发生相互作用从而放出高能光子，产生高次谐波( hhg )等现象。
Professor hafiz mahmud shirani in his historic book " punjab mein urdu " urdu in punjab stresses that this interaction between the local languages of punjab with persian of the settlers gave birth to a proto language Hafiz mahmud shirani教授在他历史的书"旁遮普邦mein urdu里" urdu在旁遮普邦注重,这互作用在旁遮普邦之间地方语言以移居者的波斯语诞生了一种proto语言。
( 3 ) generally , dam and base are operated in material viscidity status . by studying on the creep model of dam concrete and base rock , and combined them together , the coupling model of these factors is bringing forward ( 3 )通过研究坝体混凝土徐变模型和坝基岩体的蠕变模型，并将两者有机结合，分别针对混凝土重力坝和拱坝，提出了考虑坝体徐变和坝基蠕变相互作用的组合模型。
