摘要: 本文叙述了电子求根仪及其部件的结构和原理。文中着重介绍了根部件,它是借交流反馈放大器来达到90°的相移。此仪器可解六阶以下的实系数代数方程,误差小于5％。此外,还介绍了在求根仪上求解代数议程的有关知识,以便干应用此仪器。Abstract: In this paper the principle and the construction of an electronic root solver and itsmain elements are described. The root solving circuit uses a.c. feedback amplifier toestablish a 90°phase shift. This instrument can solve algebraic equations with real co-efficients up to sixth-order with an error less than 5%. At the end of this paper somereferences of solving algebraic equation on this instrument are introduced to illustratehow this instrument is applied.
