星际尘埃广泛分布于宇宙中，作为其重要组成成分之一的硅酸盐主要以非结晶硅酸盐为主，其在红外波段的光谱因Si-O键的拉伸和O–Si–O键的弯曲振动在10μm和18μm附近有两个宽且平滑的特征带且10μm附近的特征带强度更大，众多研究围绕这条吸收特征带展开但其特征没有明确结论。本研究基于JWST/MIRI提供的光谱数据进行筛选，得到了具有明显10μm附近硅酸盐消光特征的三颗原恒星HH46IRS-MIRI，TMC1A和 DG-TAU-B-MIRI1，以PER-EMB-55和HOPS370-SPECTROSCOPY作为参考星结合2MASS提供的光度数据采用对比法绘制消光曲线并进行相关分析，经高斯滤波后对于它们的吸收曲线峰值和半高全宽进行讨论，峰值分别为9.635μm，9.635μm和9.481μm，FWHM整体都比较小，有1.515μm，1.055μm，1.539μm，进一步了解硅酸盐10μm附近的消光特征。

Interstellar dust is widely distributed in the universe. Silicate, as one of its important components, is mainly amorphous silicate. In the infrared band spectrum, due to Si-O bond stretching and O-Si-O bond bending vibration, there are two wide and smooth characteristic bands near 10μm and 18μm, and the intensity of the characteristic band near 10μm is greater. Many studies have been carried out around this absorption feature band, but there is no clear conclusion on its characteristics. In this study, based on the spectral data provided by JWST/MIRI, three protostars HH46IRS-MIRI, TMC1A and DG-TAU-B-MIRI1 with obvious silicate extinction characteristics near 10μm were selected. PER-EMB-55 and HOPS370-SPECTROSCOPY were used as reference star and combined with the luminosity data provided by 2MASS to draw extinction curves and perform correlation analysis. After Gaussian filtering, the peak value of absorption curves and half-height and full width were discussed. The peak value is 9.635μm, 9.635μm and 9.481μm, the FWHM is relatively small as a whole, with 1.515μm, 1.055μm and 1.539μm, which further understand the extinction characteristics of silicate near 10μm.
