From Wikipedia, the free encyclopedia:
In physics and mathematics, an ansatz (Ger., "anset, onset"; today, "setup"; plural: Ansätze) is an educated guess that is verified later by its results. An ansatz is the establishment of the starting equation(s) describing a mathematical or physical problem. It can take into consideration boundary conditions. After an ansatz has been established, the equations are solved for the general function of interest. Typically, a word problem starts by writing down the ansatz with subsequent refinement leading to the solution of the problem.
For example, given a set of experimental data that looks to be clustered about a line, a linear ansatz could be made to find the parameters of the line by a least squares curve fit. Variational approximation methods use ansätze and then fit the parameters.
Another example could be the mass, energy, and entropy balance equations that, considered simultaneous for purposes of the elementary operations of linear algebra, are the ansatz to most basic problems of thermodynamics.
Another example of ansatz is to suppose the solutions of a homogeneous linear differential equation and difference equation to have, respectively, exponential and power form. More generally one can guess a particular solution of a system of equations and test such an ansatz by direct substitution of the solution in the system of equations.

好像是个拟合词吧, 在屋里方面用的比较多的是Bethe Ansatz 这个词组,表示一种方法,不知道你的意境是什么

文献中有两个意思。1表示的意思,用的比较多,2拟设的意思,用的较少。
