中文摘要	本文从带电粒子对D层大气电离出发,给出了宇宙线相对论粒子、非相对论粒子及低能粒子在地球大气中的电离公式,从而给出了宇宙线在电离层D层中电子产生率q(h)和电子密度N(h)的全球分布.结果表明,宇宙线产生的q(h)和N(h)具有明显的纬度效应,在极区产生的q(h)和N(h)要比低纬高得多,当截止刚度R_c=10—18GV时,q(h)的变化相差很小.太阳活动11年调制对q(h)的影响是明显的,但远小于Rc对q(h)的影响.大气密度ρ(h)对q(h)的影响主要是随高度的变化.
英文摘要	The expressions of the ionizations in ionospheric D-region by relativistic, nonrelativistic and low energy particles of galactic cosmic ray are deduced individually, according to the theory of energy loss of charged particles in the earth s atmosphere. The global distribution of electron production rate q(h) and the electron density N(h) in the low ionospheric D-region by galactic cosmic ray is presented in this paper. The results show that the electron production rate and the electron density in the D-region, galactic cosmic ray-is presented in this paper. The resulta-show that the election production rate and the electron Aensity in the D-region by galactic cosmic ray have.obvious latitude dependance. q(h) and N(h) at polar regions are 3-4 order-of magnitude higher than that at low latitudes. The changes of q(h) and N N(h)are quite small atR>IOGV. The effect of solar activity modulation on q(h) and N(h) are obvious, but its effects are far less than the effects of R, on q(h) and N(h). The effects of p(h) on q(h) and N(h) are less.
