A dielectric constant of over 100 000, with dielectric loss of less than 0.1, was found in 1.0 mol. % Ni-doped KTaO3 (KT:1%Ni) single crystals, showing temperature and frequency stabilities favorable for capacitor applications. The dielectric constant was found to depend on the electrode material, and Ag electrodes markedly enhanced the dielectric properties. This result indicates that the giant effective dielectric constant is due to a non-Ohmic electrode contact with a semiconducting KT:1%Ni.
therefor about 10 minutes until it drops sharply to zero. But if the artificiar respiration is performed in this critical point, the blood pressure increased remarkably maintain its previous level. Total spinal anesthesia was associated with R-R prolongation, disappearance of P wave and T deSpression in electrocardiogram. Bradycardia became much conspicuous when ineffective respirations con tinued and anoxia increased. It was considered that the normal cardiovascular reflex are from the sinus, vasomotor center, and the heart had been cut centrally .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
