Did the U.S. government's decision to keep interest rates down lead to increased home buying in the United States in the middle of the last decade?
在前一个十年中期的时候,美国保持低利率的决策是否导致了购房的增加呢?
The affection of parameter variation of down lead wires and top loading wires on effective height, radiation pattern, input reactance, radiation resistor and static capacitance is discussed.
同时研究了引线及顶线的各项参数变化对天线的有效高度、增益、输入电抗、辐射电阻及静电容的影响。
It is hold that one can increase static capacitance, reduce mode of input reactance and enhance the antenna gain by increasing down lead wires, their distances or lengthening the top loading wires.
研究表明,增加引线数目、引线间距和加长顶线长度均可以增加天线系统的静电容,减小输入电抗的模值,并使天线的增益有所改善。
If the lead climber were injured in a fall from any higher up, the belayer could not get him down.
