不同形式的断层土壤气集气装置对气氡观测结果影响的实验研究
|
摘要
任何一项观测都要在一定的条件下进行,不同的观测条件会产生不同的观测结果。在断层土壤气实际观测中,由于观测装置的集气室安装方式不同形成了不同形式的集气装置,而不同形式的集气装置会对气氡观测结果产生不同影响。本文就不同形式的断层土壤气集气装置对气氡观测结果的影响进行了实验研究。结果表明,集气室滞留体积对观测结果影响较大,集气室不可保留滞留体积,应控制导气管的长度和粗细,尽量减少导气管产生的滞留体积对观测结果造成影响。集气室死体积对观测结果影响不大,可保留集气室死体积。模拟观测和数字化观测应使用不同模式的集气装置。
Any observation can work well only under some certain conditions,because different observation conditions would bring different results.In factual observation of fault soil gas,collection gas chamber of different styles are formed because of the various ways to install the collecting gas chamber of observation device.And collecting gas device of different forms will have different influences on the observation results of radon in fault soil gas.The experiment has been done on different observation devices.The results indicated that,collecting gas chamber remain-volume has bigger influences on observation results.The collecting gas chamber is not allowed to reserve remain-volume.We should control the length and the diameter of transmit gas tube to reduce the bad effects to the observing results.The dead-volume of collecting gas chamber seldom have influences on observing results,we may reserve the dead-volume of collecting gas chamber.Collecting gas-device of different modes should be used in simulation observation and digital observation.
