摘要：
Based on the basis of observation data of box-beam temperature field, this study presented an comparative analysis of regulations on box-beam temperature gradient between China and foreign bridge engineering design, and proposed a new temperature difference distribution mode of concrete box beam along height of section. Finally, this study analyzed the external constraint temperature stress and temperature self-restrained stress of extra-long Longtan River bridge under different working conditions using ANSYS software, and compared them with measured results. This study provides reference for the measurement of sunshine temperature difference effect of box beam bridge.
摘要：
Metal/Semiconductor hybrid nanostructure is promising for its unique opt-electrical performance enhanced by surface plasmon resonance(SPR).However,the noble metals(Au,Ag,etc.)usually used for plasmonic are not cost-effective.In contrast,Bismuth is a cheap but promising metal with high plasmon-excitation efficiency comparable with Au.Here,the high crystalline Bi-nanorod/Si-nanodot hybrid structure is prepared by alternated sputtering of Bi and Si.FDTD simulation shows that the Bi-nanorod/Si-nanodot hybrid structure possesses red-shifted SPR resonance,in respect to that of Bi-nanorod.Some interesting SPR properties of Bi-nanorod/Si-nanodot hybrid structure including the split of longitudinal SPR mode is observed.Such hybrid-nanostructure could be useful in thermoelectric,sensor,battery electrodes,photodetector,etc.

摘要：
Centering on students' practical ability training, this paper puts forward a new teaching mode of BIM technology which is suitable for the current situation, and through the establishment of BIM skill level examination training point, organize students to participate in BIM graduation design, Establish BIM technology teaching practice base, reform BIM technology personnel training model, to further improve the teaching ideas and implementation plans of students' BIM technology application and practical ability, it provides a new idea for the BIM technology teaching in the same universities.
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 pluming 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.
