摘要
介绍了一种二级轻气炮的低温靶（温度可调范围为１８０～２９０Ｋ）系统以及高纯度低温分子液体样品的制备技术。利用该项技术，我们在低温靶中成功地制备出了符合冲击实验要求的液态ＣＯ２样品，并在２０～６０ＧＰａ区域获得七个冲击压缩数据点。经分析发现。
This paper presents a kind of low temperature target system(temperature between 180～290K)for the two stage light gas gun and the technique for preparing molecular liquid samples of high purity at low temperatures.This technique was successfully used in preparing liquid CO 2 samples.The shock compression results show that these samples totally meet the needs of shock wave experiments.We obtained seven shock compression data points between 20～60GPa.The results indicate that shock compressions induced a phase transition of liquid CO 2 at 30GPa.
