摘要：
This paper establishes evaluation indicators of the real estate marketing planning course teaching reform, uses relevant models of extension matter element theory to construct multidimensional extension matter element model of the real estate marketing planning course teaching reform evaluation, and uses cases to carry out empirical analysis. Empirical evidence shows that real estate marketing planning course teaching reform indicators are in line with the current direction of real estate marketing planning courses teaching reform. The extension matter element evaluation method can evaluate complex, intersecting and uncertain real estate marketing planning course teaching reform indicators effectively, comprehensively and objectively, which is an effective evaluation method.

摘要：
In the study, a new method based on the second-order calibration of three-way fingerprints of PAHs（SCTFP） was developed for the source apportionment of urban PM10 for the first time. First, simulated three-way data arrays of GC-MS were used to verify the feasibility of SCTFP. Then, PM10 and pollution source samples were collected during July and August, 2018 in Loudi City, China. After resolving the problems of GC-MS including baseline drift, retention-time shift and unexpected peaks overlapping, chromatographic and mass spectral profiles and concentrations of PAHs were accurately obtained by the second-order calibration of GC-MS data of samples. Last, a contribution matrix of the source to the receptor was estimated according to the obtained concentrations of PAHs. The proposed method was employed to apportion the source contributions to PM10 at five locations and reasonable results were obtained, thus presenting a promising tool for source apportionment of complex ambient particulate matter.

摘要：
Geopolymer has been applied in a great many fields such as cement and concrete, fire-proof material, heavy metal immobilization because of its excellent properties. In recent years, the additives such as fibers, carbon nanotube, graphene and inorganic mineral materials has been used to further improve the mechanical strength and other properties. The geopolymer modification with inorganic mineral materials including Ca (Mg)-rich, Si-rich, Al-rich, silicate aluminate and metal oxides mineral materials is reviewed and the action and modification mechanism of these materials in the geopolymer system are nterpreted in this paper.
