In attempting quantitative quantum mechanical treatment of chemical bonds, approximations must be made . 在试图定量地用量子力学去处理化学键时,人们必须采用近似法。
A satisfactory approximation to monochromatic light can be obtained with a filter placed in front of the arc . 在碳弧前面放一个滤光片就可以得到令人满意的近单色光。
The black-disk approximation used so far reproduces the coarse features, but not the finer details . 应用至今的黑圆盘近似值虽然再现了概貌,但不能再现更为详细的细节。
The approximation of a linear dependency between heat flow and temperature difference leads to satisfactory results . 在热流量与温度差之间,近似地采用线性关系,也能得出令人满意的结果。
The first approximation would make everything depend on the capitalized money value of the individual's prospective receipts . 第一种近似意义是以个人预期进款的资本化的货币价值为其中心。
For any approximation to be valid it must provide a result that is in some sense close to the solution of the original problem . 任何有效的近似式必须在某种意义上提供一个接近于原问题解的结果。
The validity of the centralfield approximation rests on the great mass of the sun and on the relatively great separation of the planets . 中心场近似的准确性基于太阳的巨大质量以及行星之间的巨大距离。
We find that there are reasonable approximations to all three modes, but the application of all such approximations must be made with caution . 我们发现,三种模态都有适当的近似式,但应用它们必须谨慎。
