Tlae one-dinaerasional (10) strrrogates of scalar dissipation rate as xvell as energy dissipation rateare often trsed irt place of the true ones in inx'estigations relexzant to tlae 0btrkl?of-Corrsin spectralforzaa and the joint-natr1ti['ractal nature of isotropic ttrrbuletuce xvith an advected scalar. As arestrlt of direct ntrtnerical sinaatrlation, it tttrns otrt tlaat the surrogates catrse a sitaailar ftundartaentalcharage in statistics to that cattsed by tlae ID strrrogate of energy dissipatiora rate in the treatrnentof the I{oltnogorov siumilarity varialole. The co?aditiora?t1 and trraconditional proloability densites ofthe scalar siraailarity variable btrilt frorn the trtre energ3z arad scalar dissipations are nexzer biuaaodaland always nearly G?ttrssian.
