Based on a number of general postulates a mathematical equation was derived for computing the economically justified unbalance of the prices of two different instruments for the same uses depending on concrete values of their main technical parameters. The approach thus elaborated can be used for an analysis of instruments for any uses including medical ones. The criterion suggested makes it possible as well to assess, from the economic standpoint, the efficacy of the technical servicing of the equipment.
基于一些一般假设，推导了一个数学方程，用于根据两种用于相同用途的不同仪器的主要技术参数的具体值，计算其价格在经济上合理的不平衡。由此阐述的方法可用于分析任何用途的仪器，包括医疗仪器。所提出的标准也使得从经济角度评估设备技术维护的效率成为可能。
