摘要 采用真空型傅里叶变换红外光谱法研究了硝酸钠-蔗糖二元体系气溶胶在相对湿度下降过中,蔗糖对硝酸钠气溶胶吸湿性的影响。结果表明,蔗糖的加入,使得硝酸钠气溶胶在降湿过程中结晶受阻。 The hygroscopic property of internally mixed NaNO3/sucrose(sodium nitrate to sucrose ratio was 1∶1)aerosols deposited on a Si substrate was studied by Vacuum-FTIR(Flourier transform infrared)spectroscopy.The results showed that the crystallization of sodium nitrate cannot be observed during the dehumidifying process and the hygroscopicity of the mixed aerosols is different from NaNO3 aerosols.
