Cóip statach de shonraí a easpórtáiltear ó IATE ó am go chéile atá sa chnuasach seo. Níor cheart glacadh leis gurb ionann i gcónaí an t-eolas a thugtar faoi iontráil anseo agus a bhfuil sa leagan reatha den iontráil ar IATE. Is féidir an leagan reatha sin a cheadú ach cliceáil ar an nasc atá ar thaobh na láimhe deise ag barr gach iontrála. Breis eolais »

    Sainmhíniú a way of determining the molecular weight of a polymer. Polymer molecules, even ones of the same type, come in different sizes (chain lengths, for linear polymers), so the average molecular weight will depend on the method of averaging. The number average molecular weight is the ordinary arithmetic mean or average of the molecular weights of the individual macromolecules. Tagairt Wikipedia http://en.wikipedia.org/wiki/Molar_mass_distribution [19.1.2010]
    Nóta It is determined by measuring the molecular weight of n polymer molecules, summing the weights, and dividing by n. Mn = ΣNiMi/ΣNi or Mn=Σni=1HiΣni=1Hi/Mi where Hi is the level of the detector signal from the baseline for the retention volume Vi,Mi is the molecular weight of the polymer fraction at the retention volume Vi, andn is the number of data points.
