  multilevel transmission
Finally, the relationship was extended to multilevel transmission system (MTS), and the RFC of this system was explored.
      
This is in consistence with the trend of multilevel transmission systems.
      


To investigate the repeated frequency condition (RFC) for torsional vibration of shafts' system, the transfer matrix method was adopted. Firstly, the transfer relationship from the boundary to engaging disks of double shafts' system(DSS) was constructed. Secondly, the RFC of DSS was deduced out and the methods to select mode shape were presented. Finally, The relationship was extended to multilevel transmission system (MTS), and the RFC of this system was explored. The conclusions is this: 1) the necessary...

To investigate the repeated frequency condition (RFC) for torsional vibration of shafts' system, the transfer matrix method was adopted. Firstly, the transfer relationship from the boundary to engaging disks of double shafts' system(DSS) was constructed. Secondly, the RFC of DSS was deduced out and the methods to select mode shape were presented. Finally, The relationship was extended to multilevel transmission system (MTS), and the RFC of this system was explored. The conclusions is this: 1) the necessary RFC requires the existence of joint engaging couple (JEC); 2) for DSS, the sufficient is the number of boundary transfer factors (f B) larger than 2; 3) the whole system can be split into independent groups, the total multiplicity is the sum of independent solution number of every group, the latter is the number of independent f B=0 inside the group minus 1.

借助于传递矩阵法研究了两轴系扭振的重频条件· 必要条件为:存在节点啮合对(JEC) ;充要条件为:四个边界传递系数(fB) 等于零的个数不少于3 个· 给出了两轴系存在重频时的振型选择· 多级轴系重频的必要条件与两轴系的必要条件相同,而如果所有的相邻JEC之间的传递系数(fI)等于零时,频率重数等于独立的fB 为零的个数减1· 若存在fI ≠0 ,可将它所对应的连接部分删除,从而把整个轴系的JEC分成内部不含fI ≠0 的几组,该阶频率的总重数等于各组独立解个数之和

10Gb/s optical quaternary and binary transmission systems are simulated separately with emphasis on the influence of the laser's side mode on the performance of optical quaternary and binary transmission. It is shown that the influence of the laser's side mode separation and side mode suppression ratio on the performance of optical quaternary is much greater than that on the performance of optical binary, and the laser's side mode results in larger penalty in the quaternary system than in the binary system....

10Gb/s optical quaternary and binary transmission systems are simulated separately with emphasis on the influence of the laser's side mode on the performance of optical quaternary and binary transmission. It is shown that the influence of the laser's side mode separation and side mode suppression ratio on the performance of optical quaternary is much greater than that on the performance of optical binary, and the laser's side mode results in larger penalty in the quaternary system than in the binary system. Therefore it is necessary to avoid using multilevel transmission in the practical optical communication systems.

仿真了10Gb/s光四进制和二进制传输系统,考察了激光器的边模对光的四进制传输和二进制传输的影响,研究发现边模间隔和边模抑制比对四进制传输的影响要比二进制大得多,导致代价较大,因此在实际的光通信系统中,应尽量少用多电平传输.
