摘　　要：本文推导出了控制网中观测值的精度变化与未知参数精度变化和控制网可靠性变化的关系式,即精度敏感度和可靠性敏感度的定义式。提出根据敏感度确定控制网优化设计方案的思路和方法,证明了敏感度分析法的重要性和在控制网设计中的实用性。The related formulae, namely the definition of the sensitivity of the precision and the reliability, for the changes of the precisions of the observed values and the unknown parameters and the reliability of a network, and the means of designing scheme for network optimisations based on the sensitivity are deduced. The importance to that utilized in the optimum design for network are also testfied by the practice of contrasting in various plans with the data from a mine triangulation network.
