1. The influence of the ridge position on the cutoff wavelength of the dominant mode in asymmetric single ridge waveguide is analyzed by finite difference method.
   用有限差分方法分析不对称脊波导中脊位置变化时对主模截止波长的影响。
2. In the case of homogeneous broadening only one mode can normally oscillate.
   对于均匀加宽的情况，只有一个模能正常地振荡。
3. The resonant frequency of a quartz crystal is generally determined by the size of the plate combined with the mode in which it vibrates.
   石英晶体的谐振频率通常是由组合振荡模式之振动片尺寸来决定的。
