微生物作用使粉尘胶结，在方解石胶结层中形成较大的颗粒粘结。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和差示扫描量热-热重（DSC-TG）等方法对样品的组成、形貌和热分解性能进行了表征。实验结果表明，在微生物法获得的方解石的作用下，松散的粉尘颗粒能够被粘结并形成固结层。同时，微生物法获得的样品具有上级抗风蚀能力。
Fugitive dust was cemented, forming larger particles bond in the calcite-consolidation-layer by microbial method. The particular composition, the morphology, and thermal decomposition properties of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and differential scanning calorimetry-thermogravimetry (DSC-TG). The characterization data obtained showed that loose fugitive dust particles could be bonded and formed the consolidation-layer under the effect of calcite obtained by microbial method successfully. Meanwhile, the sample obtained by microbial method had superior wind-erosion resistance.
