| 摘 要： | 采样技术是纳米级微粒物质地球化学测量方法的基础.有效的采样装置和合适的采样量是动态累积测量采样技术的两大关键.在已知隐伏矿区,利用合适的液态捕集剂进行了动态累积测量不同采样装置及抽气量效果对比试验,结果表明,手提式采样器装置系统效果明显优于大气采样器装置系统,每点采样量在9 L以上效果较好.试验表明所采物质不是真正的气体,而是纳米颗粒,需要较大压力才可以从土壤释放. |

| Abstract: | Sampling procedure is a key to get a reliable observation in the application of nano-scale particle survey to mineral exploration in overburden areas. An effective sampling device and an appropriate sampling amount constitute the major controlling factors for successful accumulation of nano-scale particles. Liquid collectors and dynamic sampling were tested to select the sampling device, layout and sampling time. The results show that the man-powered sampling device can produce much better response than the battery-driven sampler and that, to get satisfactory anomalies, we should totally collect more than 9 liters of pumping gases at each sampling site. It can be concluded that the materials the authors collected are nano-scale particles rather than real gases, and that greater power is needed to release them from the soil. |
