To determine a titre, especially by titration
n
Alternative form of transflection [A type of spectroscopic measurement produced by transmitting light through a sample and reflecting it back through the sample onto a probe.]
adj
Alternative form of ultrametricized [(mathematics) Converted to ultrametric form]
