Abstract
An operational definition for the partial conservation of the strangeness-changing vector current is given and applied to leptonic and decay. The resonance is explicitly included in the calculation and quantitative agreement with experiment is obtained. A detailed comparison with the data of Brown et al. and Dobbs et al. is given. Because of rapid variations of a form factor, it is found that the data of these two groups are not in contradiction. From the experiment of Luers et al., currents are seen to exist. decay is briefly considered. It is found that an explanation for the slowness of leptonic decay and the vector part of decay may be connected with the partial conservation of the strangeness-changing vector current.
