Times of this order are deduced directly by measuring the length of the particle track in a bubble chamber.

这样量级的时间是通过测量粒子在气泡室中径迹长度直接得到的。

To test the stability of observation method of soil radon, three synthetic observation holes were set up in the garden of Beichuan Government. Three methods are RaA, alpha particle track measurement and radon pipe measurement.

为了对比有关土氡观测的稳定性及观测结果的映震能力，在原北川县政府断层气观测场地内建立了三组综合观测孔，进行RaA法，氡管仪法和α径迹蚀刻法测试实验。
