In this paper, SLF for Dahao District, Shantou City is made, using fuzzy evaluation and transportation model to achieve optimal land allocation. The forecast results can satisfy the practical demands.
This paper introduces the function characteristics, internal construction of AD7731, and gives an applied project in SLF receiver.
本文介绍了AD 7731的功能特点、内部结构,给出了AD 7731芯片在超低频接收机中的应用方案。
The technique of electromagnetic waves in SLF (Super Low Frequency) frequency band can be investigated in the light of geophysical theory combined with radio-physical theory.
超低频 (SLF)电磁波技术利用地球物理和无线电物理相结合的原理 ,由人工产生大功率电磁波信号。
The experiment shows that using this method we can realize a SLF low noise amplifier with stable performances and meeting design requirements.
