中子诱发235U裂变的产额-能量关系在当量测定、燃耗确定等领域有着广泛的应用。通常认为裂变产物质量分布的峰区核素遵循半对数图上直线下降的规律,谷区及两翼的核素遵循台阶式上升的规律,对于过渡区的核素,则变化规律较为复杂。特别对于147Nd,长期存在着宏观应用与微观实验测量之间的分歧。简言之,通常宏观应用中采用半对数直线下降的关系曲线,
Neutron-induced 235U fission yield - the energy relationship in the determination of the equivalent, the determination of fuel consumption and other fields has a wide range of applications. It is generally considered that the peak nuclide in the mass distribution of fission products obeys the law of straight line descent on the semi-logarithmic graph. The nuclides in the valley and the two wings follow the step-rising law. The nuclides in the transition zone are more complicated. Especially for 147Nd, there is a long-standing discrepancy between macroscopic applications and microscopic experimental measurements. In short, the semi-logarithmic straight-line relationship is usually used in macro applications,
