1什么是反问题1.1反问题的概念在早期的生产活动中,人们总是遇到形形色色的障碍,经整理抽象,形成了一些数学物理问题.我们一般遇到的问题往往是由因索果,比如求解方程,必须题设给定方程的形式与系数才可以求解,此类问题我们称之为正问题(direct problem),正如在运动学中的计算问题,只有给定了初始条件,方可求得最终答案;反过来说,我们由果索因,即已知其解,反求方程中的未知量,即确定方程中的未知系数、初始条件等,这些就是反问题(inverse problem).其应用比如雷达探测、声呐探测、地下矿藏的探测等.
1 What is the anti-problem 1.1 The concept of anti-problems In the early production activities, people always encounter all kinds of obstacles, after finishing the abstraction, the formation of a number of mathematical physics problems we usually encounter problems due to the results, For example, to solve an equation, the form and coefficient of a given equation must be specified before it can be solved. Such a problem is called the direct problem. Just as in the calculation of kinematics, only given the initial conditions, We can get the final answer. On the contrary, we know the solution, the inverse of the unknowns in the equation, that is, the unknown coefficient in the equation, the initial conditions, etc. These are the inverse problems. Its applications such as radar detection, sonar detection, underground mineral exploration.
