【摘要】 协方差对于核工程等的计算日益重要,对于核数据的测量和评价者来说,只有给出了协方差矩阵才给出了数据的完整的误差信息。本文研究了协方差在核数据评价处理中的产生和传递,给出了计算公式和示例计算结果,这些结果显示了协方差产生传递的物理行为并证明了所给公式的正确性。更多还原

【Abstract】 The production and propagation of the covariance in nuclear data evaluationprocessing are studied. The calculation formulas and some calculation resultsare presented in the paper, which demostrate the physical features of the covari-ance production and propagation. The correctness of the given formulas are illu-strated.更多还原
