【摘要】 为探讨空间微重力和宇宙辐射对家蚕蚕卵的生物学效应，在俄罗斯生物卫星舱内进行了蚕卵生物叠实验，研究银河宇宙线重粒子作用于滞育期蚕卵的生物效应。卫星在轨飞行１２ｄ，测量的累积辐射剂量为１．８８ｍＧｙ。蚕卵样本分为轨道飞行重粒子击中组、轨道飞行重粒子未击中组、地面实验组与地面对照组。观察了各组第一代蚕卵的孵化率、发育过程、蚕茧重量和蚕蛹重量，结果表明，各实验组的上述观察指标均无明显差异，但轨道飞行组的蚕茧重量均值高于地面对照组，这一现象值得进一步研究。更多还原

【Abstract】 To study the effect of the cosmic ray HZE particle(High Z and Energy)on the silkworm eggs the biostack experiment was done on board Russian biosatellite in 1993.The biostack consisted of silkworm eggs and CR-39 plastic track detector,The experimental silkworm eggs were divided into 4 groups:flight hit,flight non-hit,ground simulation,ground control. Then the hatching,the developments of the silkworm,the weight of the co-coons and the silk of the first generation of each group were observed.The results show that the effect of HZE particle on above indices of silkworm are not significant.On the average,the cocoon weights of the flight groups are slightly higher than that of the ground group:and it is worth while to pay special attention in later investigations.更多还原
