项目摘要

We get following results. (1) From the observation with Ginga satellite. a) Discovery cyclotron absorption lines in the gamma-ray burst, which confirm the netron star surface as the birth place of the gamma-ray burst. b) Discovery of the existence of iron emission lines of 6.7 KeV at the central region of our galaxy. c) The time lag of the time variation of the X-rays from Cyg X-1 can not be explained by the Compton scattering model, which are widely assumed to produce high energy X- rays in Cyb X-1. d) There is a structure in the lag time of GX339-4 which suggests the existence of the Compton scattering cloud of 2 10^9cm. e) More than 13 X-ray nova were discovered with the all sky monitor onboard Ginga, two of which are black hole candidates. f) cyclotron absorption ines qre observed in several X-ray pulsars. g) Rapid time variation of the iron line intensity of AGN NGC6814 is delayed within 256 sec from those of the continuum X-ray component of the source. f) The iron abundance of the hot gas in the clusters of galaxies are inversely proportional to the temperature of the hot gas. (2) a) The enhancement of the infrared intensity from SN1987A is due to the matter ejected by the eruption of the super nova. b) IR intensity of 3.3 micrometer is a good indicator of the activity of the star production. (3) There is unisotropy in the primary in the primary cosmic rays of the average energy of 10^<13>eV. There is cosmic ray flow along the direction of R.A. Oh, Dec. 20 deg., (4) From the observations of the ground level enhancement of cosmic rays due to the large soler flare occurred on September 29, 1989, this enhancement is due to the solar proton of 10-25 GeV and these particles are firstly trapped by the interpianetary magnetic field and then flow to the earth along the magnetic field line.

我们得到以下结果。(1)从Ginga卫星的观测。a）发现γ射线暴中的回旋吸收线，证实了中子星星表面是γ射线暴的诞生地。B）发现银河系中心区域存在6.7 KeV的铁发射线。c）来自Cyg X-1的X射线的时间变化的时滞不能用康普顿散射模型来解释，康普顿散射模型被广泛认为在Cyb X-1中产生高能X射线。d）GX 339 -4的滞后时间存在一个结构，表明存在2 × 10^9cm的康普顿散射云。e）Ginga上的全天监视器发现了超过13颗X射线新星，其中两颗是黑洞候选者。f）在几个X射线管中观察到回旋吸收线。g）活动星系核NGC 6814的铁谱线强度的快速时变比源的连续谱X射线分量延迟256秒。f）星系团中热气体的铁丰度与热气体的温度成反比。(2)a）SN 1987 A红外线强度的增强是由于超新星爆发时喷射出的物质。B）3.3微米的IR强度是星星产生的活性的良好指示。(3)在平均能量为10^ eV的初级宇宙线中，初级宇宙线具有各向异性<13>。宇宙射线流沿着R. A方向。哦，12月20日，(4)从1989年9月29日太阳大耀斑引起的宇宙线地面增强的观测结果看，这种增强是由于10-25 GeV的太阳质子首先被星际磁场捕获，然后沿沿着磁力线流向地球。
