Abstract :
随着网络舆情对整个社会的舆论影响力越来越大,为了有效的防控恶性事件,实时监控网络舆情也越来越尤为重要.本文针对舆情短文本信息的特点,提出基于组合神经网络自动聚类方法来构建舆情短文本的表示模型,通过特征词语义相似度构建词簇.实验结果表明:在海量文本分析和舆情发现的过程中,该方法可以有效提高舆情短文本构建表示模型的精度,提升舆情发现效率.

Abstract :
This paper studies the influence of stone dust on adaptability of polycarboxylate superplasticizer and cement by the experiment of paste slump and mortar slump flow. The results indicate that polycarboxylate superplasticizer mixed in mortar increases with stone dust mixed because of large specific surface and water demand of stone dust. There is little effect on fluidity loss when the dosage of stone dust is below 18%, and it will increase significantly with the dosage more than 18%. The adaptability of polycarboxylate superplasticizer and cement will be bad when the content of stone dust in manufactured sand is over 10%. The adaptability of polycarboxylate superplasticizer and cement can be evaluated by the method of mortar slump flow. © 2017 Trans Tech Publications, Switzerland.

Abstract :
This paper presences the influence of coarse aggregate-space coefficient on the rheological properties of self-compacting concrete (SCC). The results indicate that coarse aggregate-space coefficient has significant influence on slump flow and V-funnel flow time of SCC, when the maximum aggregate particle size is 16mm and the volume ratio of sand and motor is 0.43, meanwhile water binder ratio is 0.38. The higher the coarse aggregate-space coefficient, the lager the slump flow, the shorter the V-funnel flow time. The range of coarse aggregate-space coefficient of SCC is suitable for 1.31∼1.58 under the condition of the paper. The suitable range can guarantee excellent rheological properties and stability of SCC mixture. There is little effect of coarse aggregate-space coefficient on compressive strength in this paper tests. © (2015) Trans Tech Publications, Switzerland.

Abstract :
通过对等角钢格构式架构进行设计分析,研究对比了不同结构截面选型、主材计算长度、受力方向与杆件内力等因素作用下对构架柱的影响,并应用有限元软件计算检验.结果表明,结构截面选型和主材计算长度大小的选取对主材应力比影响较大;弦杆不同布置型式对主材应力比影响较小;等角钢变截面格构柱,斜材内力在变截面处会出现突变.该结论为设计截面选型及如何调整设计参数提供参考,为合理选取主、斜材提供依据,有利于节省钢材.
