In this article,we use the CAP method to invert the focal mechanism of Xinyuan-Hejing M S6. 6 earthquake on June 30,2012. Our result shows that the best double couple solution of the M S6. 6 event is 299°,68° and 164° for strike,dip and rake angles respectively. The other nodal plane is 35°,75° and 23°. The azimuth and dip angle of the P-axis are 166°and 5°,those of the T-axis are 258° and 26°. The moment magnitude is 6. 3. The estimated focal depth is about 21 km. The predominant rupture direction of this seismic sequence is NWW. The dip angles are between 60° and 90°. The rake angles are in the majority of ± 180°± 30°. The predominant strike of the azimuthal angle of the P-axis is near NS and T-axis is near EW. Preliminary analysis indicates that nodal plane I is the seismogenic fault,which is a NWW-trending,nearly upright left-lateral strike-slip *** displacement property,the principal compressive stress of this M S6. 6 earthquake and the P-axis preponderant orientation of this seismic sequence agree with the characteristics of the tectonic stress field of the focal area and its surroundings.

To promote the recycling of reclaimed asphalt pavement(RAP),epoxy resin was used to prepare the epoxy-recycled asphalt *** effect of epoxy resin on the properties of aged asphalt binder was investigated based on the tensile test,flexural creep test,and laser scanning confocal *** curing characteristics and the mechanical performance of recycled asphalt with different epoxy contents were *** results show that the low-temperature performance,ductility,and strength of the aged asphalt binder were significantly improved when the epoxy content reached 40%.The curing time of epoxy-recycled asphalt should be at least 4 d to ensure the formation of good internal spatial network structure.

Government-sponsored venture capital(GVC) has been used to support financially constrained start-ups as an important policy tool in China. Typically, to motivate the social capital to invest in start-ups, GVC provides subsidies for them to bridge the funding gap in the early-stage venture capital market. However, the effect and mechanism of GVC affecting social capital investment have not been clearly studied. In this paper, the authors not only develop a game model to analyze this issue in theory, but conduct an empirical study by analyzing the 14741 records matched by propensity score matching(PSM) of Chinese venture capital market data from 2011 to 2021. The proposed findings are as the follows. Firstly, the subsidies offered by GVC will simultaneously increase the returns and risks of investments in start-ups of social capital with more volatile incentive effect of GVC. The incentive effect of GVC is only effective when the returns resulting from the subsidies outweigh the risks they introduce. In the context of the Chinese venture capital market, the incentive effect of GVC is effective. Secondly, the incentive effect of GVC is more pronounced in high-tech industries, which can be attributed to the signaling effect facilitated by GVC. In this context, the subsidy mainly helps social capital to bear the costs associated with screening potential investments. Thirdly, the incentive effect of GVC is more significant in underdeveloped venture capital markets, which can be explained by the “virtuous cycle” effect, in which GVC plays a pioneering role in establishing a more robust early-stage market trading system. By examining these three points, this study contributes to a better understanding of how GVC can effectively guide social capital investment, especially in the Chinese landscape.
