英文摘要	Recently, statistical correlations were found between near-infrared luminosities and ring sizes in field resonance-ringed galaxies. These correlations are proposed as a new class of tertiary distance indicators in the nearby universe (where redshifts less than or similar to 30, 000 km s(-1)). The most suitable application of the indicators will be to measure the Hubble constant. Detailed formulae are derived to evaluate distances to field ringed galaxies and H-0, as well as the error levels involved in using this method. Numerical simulations show that through the measurements of over a thousand nearby ringed galaxies the method can yield a value of H-0 with its root-mean-square random error within approximate to 6% and systematic error most likely below approximate to 10% (excluding the systematic error due to other indicators that are used to calibrate the correlations). Future such measurements should help to check the H-0 values from conventional methods.
