T2 = T1 × (D2 ÷ D1)1, 06

Formula variables qhia:

  • T1- Lub sijhawm siv dhau qhov kev ncua deb D1;
  • T2- kwv yees lub sij hawm los npog qhov deb D2;
  • D1 yog qhov kev ncua deb uas tus neeg ncaws pob yav dhau los tau them rau lub sijhawm T1;
  • D2 - qhov kev ncua deb uas tus neeg ncaws pob npaj yuav npog hauv lub sijhawm xav tau T2.

Tom qab ntawd, Peter Riegel tau qhia meej tias cov qauv siv rau kev ua lub cev ntev li ntawm 3.5 txog 230 feeb. Txawm li cas los xij, nws tsim nyog rau kev khiav, ua luam dej thiab taug kev.
