通过理论分析和实验测量，基本上确定了Ｘ射线本底产生的原因，并采取了有效的克服办法。使Ｘ射线引起的本底计数降低到原来的２／５。极大地提高了１４Ｃ的探测效率和样品测量的精确度及丰度灵敏度。
Through theoretical analysis and experimental measurement, the causes of X-ray background are basically determined and effective measures are taken to overcome them. The X-ray background count is reduced to 2/5. Greatly improve the 14C detection efficiency and sample measurement accuracy and abundance sensitivity.
