用热天平在不同温度（T=673-973 K）和水蒸气压（PH_2 O =0.9-12.8 kPa）下测量了SrZr_（0.95）M_（0.05）O_（3-α）（M=Ga，Sc，Y和Nd）中的质子浓度。在所考察的压力和温度下，这些样品中质子浓度的大小顺序为Sc>Y>Ga>Nd。通过平衡评估，我们估计在这些样品中的最大可能的质子浓度约为2.0摩尔%。测量了这些样品的红外（IR）吸收光谱。吸收带可以由四个（M=Ga，Y，Nd）或三个（M=Sc）高斯带拟合。
SummaryProton concentration in SrZr0.95M0.05O3-α (M=Ga, Sc, Y and Nd) was measured with a thermobalance at different temperatures (T=673-973 K) and water vapor pressures (PH2O=0.9-12.8 kPa). At all the pressures and temperatures examined, the amount of proton concentration in these samples is in the order of Sc>Y>Ga>Nd. By an equilibrium evaluation, we estimated the maximum possible proton concentration about 2.0 mol% in these samples. Infrared (IR) absorption spectra are measured in these samples. The absorption bands can be fitted by four (M=Ga, Y, Nd) or three (M=Sc) Gaussian bands.
