signal process method for NQR signals is presented, which is based on wavelet transform and specially designed for the detection of pentaerythritol tetranitrate with NQR.───为提升NQR信号信噪比，根据NQR信号的特点，提出了一种基于改进阈值函数小波变换的NQR信号去噪方法。
PETN, or pentaerythritol tetranitrate, was the explosive material found on the suspect.───PETN即四硝基季戊四醇，是在这名嫌疑人身上发现的爆炸材料。
L3's website claims PassPort can identify a number of types of explosives, including frequent al-Qaida favorites like Pentaerythritol tetranitrate, or PETN and triacetone triperoxide, or TATP.
They included Pentaerythritol tetranitrate, or PETN, which was used in the 2001 airliner shoe-bombing attempt as well as in last month's airplane cargo bombs, prosecutors said.
In this work, a signal process method for NQR signals is presented, which is based on wavelet transform and specially designed for the detection of pentaerythritol tetranitrate with NQR.
