摘　　要：处于高纬向日面的极隙区是太阳风能量、动量和质量可以直接进入地球磁场并到达地球的近地空间的区域。本文简要介绍了极隙区的观测和研究，综述了极隙区的粒子沉降、场向电流、等离子体对流和电离层电流的特征。The energy, momentum, and mass of solar wind can directly enter geomagnetic field and arrive the earth's near space through the cusp/ cleft, a regions centring on local noon at high latitudes and extending around the dayside of the earth. In this paper, a brief introduction is made for some observations and studies in the cusp /cleft, and the characteristics of particle precipitation, field-aligned currents, plasma convections and ionospheric currents in this regions are summarised . It is therefore a necessary work in studis of the cusp/ cleft.
