摘要：

Wave-particle interactions are a key influence on radiation belt particle dynamics. Here electron cyclotron resonance with very-low-frequency chorus, extremely-low-frequency hiss, and electromagnetic ion cyclotron waves in the Earth's dipole magnetosphere is analyzed. In this first of two companion papers, it is assumed that wave propagation is field aligned. The aim of this investigation is to carry out a detailed examination of "resonance zones" in (L,lambda) space (where L denotes magnetic shell and lambda the magnetic latitude). These zones are regions in which electron cyclotron resonance occurs for a given wave mode and waveband. Identification of resonance zones is a useful aid in the construction of realistic models of radiation belt electron dynamics, and is hence also useful in the interpretation of observational data.
