用锰浴法绝对测量中子源强度时,硫酸锰的浓度与计算中子强度有直接的关系,所以必须准确测定硫酸锰在溶液中的浓度。为此分别采用了密度法、重量法及容量法测定了硫酸锰溶液的浓度。结果表明,三种方法测定同一浓度的硫酸锰溶液符合较好,精密度好于0.15%。
With the absolute measurement of neutron source intensity by the manganese bath method, the concentration of manganese sulfate has a direct relationship with the calculated neutron intensity, so the concentration of manganese sulfate in the solution must be accurately determined. For this purpose, the density, weight and volumetric methods were used to determine the concentration of manganese sulfate solution. The results show that the three methods to determine the same concentration of manganese sulfate solution in good agreement, the precision better than 0.15%.
