求翻译：远场区是指电磁场和天线分离开来，以平面波的方式在空间传播。近场和远场的界限取决于传输的频率和电线尺寸，通常由下列两种近似公式来计算两者边界：是什么意思？

Far-field zone is separated from the electromagnetic field and antenna to the way the plane wave propagation in space. Near-field and far-field boundaries depends on the transmission frequency and wire size, usually by the following two formulas to calculate the approximate boundary between the two:

Far-field area, that is to say an electromagnetic field and the antenna away from the way, with a plane wave in space communications. Near-field and far-field boundary depends on the transmission of frequency and wire size, usually by the following two similar formula to calculate the boundaries:

The distant field area is refers to the electromagnetic field and the antenna separates, by plane wave way in spatial dissemination.The near field and the distant field boundary is decided by the transmission frequency and the electric wire size, usually calculates both boundary based on the followi

Separated from the far field is the electromagnetic fields and antenna, a Plane wave basis in space communication. Near-field and far field limit depends on the frequency and size of wire transmission, usually made of either of the following approximate formula to calculate the boundary between:
