求翻译：非线性展开或逼近研究的的意义在于，它可以解决有限项展开条件下，对于任意大变化范围描述的有效性、任意逼近精度描述的高效性问题。是什么意思？

The nonlinear Expand Approximations for the significance is that it can solve the finite number of terms to commence under the conditions described for any big changes in the scope of the validity of any approximation precision description of the efficiency.

Non-linear or approaching the study of limited significance lies in the fact that it can be solved for the arbitrary conditions, the start of the changes described the effectiveness, arbitrary approaching precision describes the efficiency problem.

The non-linearity launches or approaches the research the significance to lie in, it may solve the limited item to launch under the condition, regarding the sweeping change scope description validity, willfully approaches the precision description willfully the highly effective question.
