报道了聚乙烯对苯二酸酯（简称PETP）固体核径迹探测器时裂变碎片记录性能的实验研究．在改变温度、蚀刻时间和蚀刻液浓度等条件下测量了裂变碎片径迹平均直径的变化。实验结果表明：蚀刻液温度的变化对裂变碎片径迹的影响最大；而浓度和蚀刻时间的影响不大.同时用低能16O重离子辐照PETP探测器，并得到了它的标定曲线．
This paper reports the experimental research on the recordability of fission fragments in polyethylene terephthalate (PETP) solid nuclear track detector. The change of average diameter of fission fragments was measured under the conditions of changing temperature, etching time and etching solution concentration. The experimental results show that the temperature of the etching solution has the greatest influence on the fission track, while the concentration and etching time have little effect, while the PETP detector is irradiated with low energy 16O heavy ions and its calibration curve is obtained.
