Thus,for instance,it may come as a shock to mathematicians to learn that the Schrodinger equation for the hydrogen atom is not a literally correct description of this atom,but only an approximation to a somewhat more correct equation taking account of spin,magnetic dipole,and relativistic effects;and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field-theoretical equations.
因此,举例来说,可能是个震惊对数学家来说,了解到 Schrodinger方程式氢原子的并不是一种完全正确的描述对该原子的,而仅仅是个近似值,趋近于一个在某种程度上更为正确的方程式考虑到自旋、磁性偶极子,以及相对论效应;而这个修正的方程式就其本身而言也只是一个不完美的近似值,无限趋近于的一整套量子场理论方程式。
In large part as a consequence of the feminist movement,historians have focused a great deal of attention in recent years on determining more accurately the status of women in various periods.
在很大程度上,由于女权主义运动的缘故,史学家集中了大量的注意力近年来,确定更为准确地妇女的地位在各个历史时期。
