空气中氚的取样与测量方法
氚（氙）是一种最重要的放射性气体，可用来判断地表环境的持久变化。因此，空气中氚的取样与测量是比较重要的工作。目前，空气中氚的取样与测量主要有以下几种方法：
一、采用HP-GC-TC-TEA-MS分析。在加热土壤中收集空气样品，然后通过气相色谱-质谱(HP-GC-MS)分析技术对空气样品中的氚进行测量。干怎么组词

三、使用气相色谱-原子荧光法测定空气中氚的浓度。该方法通过将空气中的氚气体以小流量（0.5sccm）介入到原子荧光仪中，然后测定氚气体的荧光强度，据此确定空气中氚的浓度。
四、使用气体测试装置进行空气氚检测。该装置可以避免土壤中氚气体与温度变化对测量结果的影响，更易于控制和测量精度更高。
总之，空气中氚的取样与测量通常采用HP-GC-MS、原子吸收法、原子荧光法和气体测试装置等技术，以准确可靠的数据检测空气中氚的含量，有助于我们进一步研究空气中氚的源头及分布特征。
In recent years, the examination and measurement of xenon in air has always received the attention of many scientists, becau xenon (Xenon) is an important radioactive gas that can be ud to judge the persistent change of the surface environment. Therefore, the sampling and measurement of xenon in air is quite important. At prent, the sampling and measurement of xenon in air mainly adopt the following methods.

This method is to introduce the xenon gas in the air into the atomic fluorescence spectrometer with a small flow rate (0.5Sccm), and then measure the fluorescence intensity of xenon gas to determine the concentration of xenon in the air.
The fourth one is to u a gas testing device for xenon detection in air. This device can avoid the influence of xenon gas and temperature change in soil on the measurement results, which is more easy to control and with higher accuracy.
In conclusion, the sampling and measurement of xenon in air usually adopt HP-GC-MS, atomic absorption method, atomic fluorescence method and gas testing device to accurately and reliably detect the content of xenon in air, which is helpful for us to further study the sources and distribution characteristics of xenon in air.男生名字大全
