利用计算机模拟研究了非均匀电场产生的赤道扩展Ｆ的时空演变。非均匀电场能在赤道电离层Ｆ区底部触发Ｒａｙｌｅｉｇｈ－Ｔａｙｌｏｒ不稳定性，导致等离子体泡形态。计算中非均匀电场的幅度取为０．２５－１．００ｍＶ／ｍ，所产生的等离子体泡在２０００ｓ以内就能穿过Ｆ峰达到５４０ｋｍ的高度。所得结果阐明了非均匀电场在赤道扩展Ｆ中的作用，指出了产生等离子体泡一种可能的扰动源。由于Ｅ区和Ｆ区电场是相互影响的，从而揭示了Ｅ区和Ｆ区扰动的相互联系。
The space-time evolution of equatorial expansion F generated by non-uniform electric field was studied by computer simulation. The non-uniform electric field can trigger Rayleigh-Taylor instability at the bottom of the F region of the equatorial ionosphere, resulting in the plasma bubble morphology. Calculating the magnitude of the non-uniform electric field in China is 0.25-1.00mV / m, and the generated plasma bubbles can pass through the F peak to a height of 540km within 2000s. The results illustrate the role of inhomogeneous electric fields in equatorial expansion F and indicate a possible perturbation source for plasma bubble generation. Since the electric fields in zones E and F interact with each other, the interrelation of disturbances in zone E and zone F is revealed.
