- Abstract Coupling between resonant cavity and R.F. generator is an important subjectifor R.F. accelerators.
摘要 加速谐振腔与高频发生器的耦合,历来是高频型加速器的重要问题。 - The spectrum of amplitude modulated signal are two half magnitude spectrums of base band signal positive and negative shifted by a carrier or R.F. frequency.
调幅讯号之频谱为一半强度基频讯号之频谱分别正负位移一射频或载波之频率。 - This thesis is divided into two parts.In the first part, we deposite the flake-like graphite with the mixture of methane, hydrogen and argon in the R.F. magnetron sputtering system.
中文摘要本论文共分成两部份,在第一个部分是在射频溅镀系统中通入甲烷、氢气和氩气的混合气体,成长出片状结构的石墨。
