dc.description.abstract	We have analyzed ali the archival IUE images of the DA4 and DAS white dwarfs with model atmosphere fluxes incorporating the quasimolecular opacities to obtain a consistent set of temperatures for both the variables and nonvariables in and around the ZZ Ceti instability strip. We have found four nonvariable stars inside the instability strip. Taken at face value, this indicates that temperature is not the only parameter that determines if a star pulsates or not, but the large uncertainties in the temperature determinations makes it impossible for us to offer this as more than just a suggestion at the present time.	en
