单词	ansatz
释义	ansatz /ˈansats / noun Mathematics An assumption about the form of an unknown function which is made in order to facilitate solution of an equation or other problem.The conventional ansatz for the B-state dominance in S65T is that the negative charge on the anionic Glu - 222 prevents wt-Cro ionization in the GS and conversely, the neutral Glu - 222 in the S65T mutant permits its permanent ionization.... This observation is harder to rationalize within the conventional ansatz, that Thr - 203 rotates to form the HB to the anion only after ESPT. Using this approximation ansatz, several problems concerning planar rods reduce to elementary geometry, as seen from the following simple but illustrative examples. Origin 1940s: from German Ansatz 'approach, attempt'.
