摘　　要：应用ＭｏｎｔｅＣａｒｌｏ方法对太阳Ｘ射线暴（１—８Ａ及０．５—４Ａ）与地球大气相互作用过程进行跟踪模拟，得到了Ｘ射线暴在电离层Ｄ层产生的电子产生率，并计算了由此产生的宇宙噪声吸收值．The Monte Carlo method is applied to simulate solar X-ray bursts (1-8 A, 0.5-4 A) transportation in earth's atmosphere. And the electron production rate due to solar X-ray bursts penetrating in ionospheric D-layer is calculated. From that, we can get the value of cosmic noise absorption. A example result of solar X-ray bursts is compared with the value of Riometer absorption observed in antarctic Zhong-Shan station, showing very good correlation.
