noun
reciprocity theorem
A principle in physics stating that the response at one point due to a source at another is symmetric under exchange of source and receiver, often applied in electromagnetism, acoustics, and structural mechanics.
相反定理は、電磁気学においてアンテナの送受信特性が等しいことを示す。
The reciprocity theorem shows that the transmitting and receiving characteristics of an antenna are equal in electromagnetism.
構造力学の相反定理を使うと、ある点の荷重による別の点の変位が計算できる。
Using the reciprocity theorem in structural mechanics, the displacement at one point due to a load at another can be calculated.
