Tw. measuring methods of the w.de absorption spectrum by distributed feedback laser diodes （DFB-LDs） are presented in detecting the w.ter vapor absorption line. One is the subsection scanning method, and it takes advantage of the w.de spectrum tuning range by the temperature modulation and fast spectrum tuning speed by current modulation. Specifically, this method is realized by dividing a target spectral region into several sections w.ich correspond to the specific temperature of DFB-LD, scanning every section by current modulation for hundreds times, and averaging the data to raise the signal to noise ratio （SNR）, then combining all sections to get the w.ole spectrum. An accuracy of 10ppmv had been obtained in the measurement of w.ter vapor w.th a 10-cm path length by this method. Another is data fitting method, based on the absorption line-shape function; the absorption line can be described by fitting w.th partial measured data. The fitting absorption line w.s fitted w.ll w.th the measured data, and the square of correlation coefficient （R-square） w.s no less than 0.99.

Rechargeable zinc-air batteries(ZABs) have recently draw. great attention in energy research due to their high theoretical capacity,low.costs, and inherently safe nature [1–3]. How.ver, the sluggish cathode reactions necessitate the development of bifunctional oxygen electrocatalysts w.th low.r ΔE indicator values. The ΔE indicator is commonly employed to quantitatively evaluate the electrocatalytic activity of a bifunctional oxygen electrocatalyst,representing the overall overpotential from oxygen reduction reaction(ORR) to oxygen evolution reaction(OER).
