The results show that the developed antenna choke ring can effectively reduce the multi-path effects and can improve the interference-resistant ability of the single frequency GPS receiver, NTSCGPS-1.

结果表明，研制的天线扼流圈可有效地削弱多路径效应的影响，并可明显地改善单频GPS接收机ntscgps - 1的抗干扰能力。

The line of argument in these letters, in favour of cultural diversity and against centralisation in London and interference in the affairs of Scotland, has a very contemporary ring and is the reason why they have been called the first manifesto of modern Scottish nationalism.
