针对两类与水锤控制密切相关的水锤反问题,构造了一种判别函数,在原问题有唯一稳定解的条件下,用此判别函数可以确定出反问题解的范围,并给出了具体解法。以水锤反问题为理论基础,建立了压水堆一回路水锤控制的方法。理论分析和数值计算表明,用求解反问题来对压水堆进行水锤控制是一种准确可靠而又简便易行的方法。

Aimed at two types of water hammer inverse problems closely related to water hammer control, a discriminant function is constructed. Under the condition that the original problem has a unique stable solution, the discriminant function can be used to determine the scope of the inverse problem solution and gives the specific solution. With water hammer inverse problem as the theoretical basis, a method of water hammer control of PWR primary loop was established. Theoretical analysis and numerical calculation show that it is an accurate, reliable and easy-to-use method to solve the water hammer problem of PWR by solving the inverse problem.
