When we wear ill-fitting clothes, or feel over-or under-dressed for an event, it's natural to feel self-conscious or even stressed.

By theoretical derivation, the partial derivatives of the deviation between the humidity sensing characteristic curve and the fitting line to the self-resistance are obtained.

Electrode and electrolyte material fitting to IT-SOFC were synthesized by the combination of sol gel and citric acid-nitrate low temperature self-propagating combustion method.
