Scale analysis (or order-of-magnitude analysis) is a powerful tool used in the mathematical sciences for the simplification of equations with many terms. First the approximate magnitude of individual terms in the equations is determined. Then some negligibly small terms may be ignored.

Property Value
dbo:abstract
  • En mathématiques, l'analyse d'échelle est une méthode d'approximation utilisée pour simplifier des équations comptant plusieurs termes en comparant leur ordre de grandeur et leur influence sur le phénomène modélisé. Le principe est de garder le terme principal et de négliger les autres termes secondaires. (fr)

  • Análise de escala ou análise de ordem de magnitude é uma ferramenta poderosa utilizada nas para a simplificação de equações com muitos termos. Primeiro a amplitude aproximada de termos individuais nas equações é determinada. Em seguida, alguns termos desprezíveis podem ser ignorados. (pt)
  • 尺度分析(Scale analysis),或稱量级分析(order-of-magnitude analysis),是一个應用于数学科学的工具,用于简化含有多项式的公式。首先确定方程中的某一项的量级。然后一些小到可以忽略不计的项可能会被忽略。 (zh)
