摘　　要：为了探明水稻种子在空间搭载后发生突变的原因,设计了一个“三明治”式的实验系统,采用CR-39固体核径迹探测器来探测空间离子,并利用实验系统中空间离子径迹与水稻种子的相对位置,来确定被离子击中的种子和部位。To ascertain cause of mutation of rice seeds induced by space loading in spaceship “Shen-zhou Ⅲ”, a “sandwich” experimental setup was designed. CR-39 solid-state nuclear track detectors were used to detect space heavy ions. Based on the position of track corresponding to seed in the setup, the seeds and their sites hit by ions were determined.
