bounded
  کرانمند، کراندار   
karânmand (#), karândâr (#)

Fr.: limité   

General: Having bounds or limits.
Math.: Of a function, having a range with an upper bound and a lower bound.

Adj. from → bound.

bounded function
  کریای ِ کرانمند، ~ کراندار   
karyâ-ye karânmand, ~ karândâr

Fr.: fonction bornée   

The function y = f(x) in a given range of the argument x if there exists a positive number M such that for all values of x in the range under consideration the inequality | f(x) | ≤ M will be fulfilled. → unbounded function.

bounded; → function.

density-bounded H II region
  ناحیه‌ی ِ H IIی ِ چگالی‌کرانمند   
nâhiye-ye H II-ye cagâli karânmand

Fr.: bornée par la densité   

An → H II region which lacks enough matter to absorb all → Lyman continuum photons of the → exciting star(s). In such an H II region a part of the ionizing photons escape into the → interstellar medium. See also → ionization-bounded H II region.

density; → bounded; → region.

ionization-bounded H II region
  ناحیه‌ی ِ II H‌ی ِ یونش‌کران‌مند   
nâhiye-ye H II-e yoneš-karânmand

Fr.: région H II bornée par ionisation   

An H II region whose → exciting star(s) do not have enough → Lyman continuum photons to ionize the whole region. → density-bounded H II region.

ionization; → bounded; → H II region.

unbounded function
  کریای ِ بیکران   
karyâ-ye bikarân

Fr.: fonction non bornée   

The function y = f(x) in a given range of the argument x if there is no number M such that for all values of x in the range under consideration the inequality | f(x) | ≤ M will be fulfilled. → bounded function.

un-; → bounded function.
