低热硅酸盐水泥在特高拱坝中的应用

针对中热硅酸盐水泥在水化过程中释放的热量相对较多,难以满足特高拱坝温控防裂要求的问题,本文从研究低热硅酸盐水泥性能的角度出发,结合其在等特高拱坝中的应用情况,得出:相比于中热硅酸盐水泥,低热硅酸盐水泥在水化过程中释放的热量相对较小,有利于控制混凝土最高温度和温升速率,低热硅酸盐水泥的综合抗裂性能更好.目前,在溪洛渡、白鹤滩等特高拱坝应用低热硅酸盐水泥后并未发现任何裂缝,为在其他300级特高拱坝建设中使用低热硅酸盐水泥提供依据.

Impact of state-dependent oil price on US stock returns using local projections

In this paper, we investigate the impact of oil prices on both aggregate and industry US real stock returns over the period 1973–2017. The empirical analysis contributes to the related literature introducing a state-dependent oil price (high and low) and the local projections approach. Our main finding is that, depending on the nature of the shock and industry, the negative effects of oil price shocks become exacerbated -and the positive effects get moderated- if oil prices are already high.     

Crowdsourcing-based semantic relation recognition for natural language questions over RDF data

ABSTRACT

Natural language query systems over RDF data need to rely on the semantic relations in query. First, we propose the new crowdsourcing model that used to produce semantic relations dataset. The model not only inherits completeness of the iterative model and accuracy of the parallel model, but also saves human resources. Second, we mine the rules of semantic relation recognition from the correlations between dependency structures and semantic relations. Third, we propose an algorithm of semantic relation recognition for natural language query over RDF data, and experiments demonstrate that it can recognize more semantic relations than existing methods.     

农民养老问题亟待解决
