用中子吸收法测定岩样中的硼含量,在苏联及西方国家已经作了不少工作,效果良好。其特点是岩样不需进行化学处理、速度决、成本低、灵敏度及分析精度均可与化学分析相比较。我们对我国某些硼矿区样品作了研究,现将这项工作作一简单介绍。 Determination of boron in rock samples by neutron absorption has done a good job in the Soviet Union and western countries. It is characterized by rock samples without chemical treatment, the speed of decision, low cost, sensitivity and analysis accuracy can be compared with the chemical analysis. We have made some research on the samples of some boron mining areas in our country. Now we will make a brief introduction of this work.
