共振天线 [gòng zhèn tiān xiàn]
resonant antenna
- 在托卡马克中采用离子回旋共振加热时，为了更好地保护天线，常常把天线置于洞穴内。
When the ion cyclotron resonance heating is adopted in Tokamak, in order to protect the antenna in a better way, the antenna is usually placed in the cavity. - 原因之一是，天线的全长取决于要撷取的播送类型；如果天线的长度是波长的一半，就能让传来的无线电频率波达到最佳共振。
Antenna span, for one, is dictated by the type of broadcast it captures; an incoming radio-frequency wave resonates best when an antenna's length is one half that of the wavelength. - 原因之一是，天线的全长取决于要撷取的播送类型；如果天线的长度是波长的一半，就能让传来的无线电频率波达到最佳共振。
