Salinity txhais li cas?

Dej hiav txwv ntsev feem ntau txhais tau tias yog ntsev concentration (piv txwv li, Sodium thiab Chlorure) hauv dej hiav txwv. Nws yog ntsuas nyob rau hauv chav tsev ntawm PSU (Practical Salinity Unit), uas yog ib chav tsev raws li cov khoom ntawm dej hiav txwv conductivity. Nws yog sib npaug rau ib txhiab lossis (o/00) lossis rau g/kg.

Dab tsi yog salinity hauv thaj chaw?

Salinity txhais tau tias qhov piv ntawm qhov hnyav ntawm cov khoom yaj thiab qhov hnyav ntawm cov qauv dej hiav txwv … dej ntau dua li dej ntsev tsawg. Salinity kuj nce qhov ntom ntawm dej hiav txwv.
