  Sulfate attack is an environmental issue for concrete structure exposed to aggressive environment contains sulfate ions.The interaction of cementitious materials with sulfate solutions leads to a reaction front within the porous material.The consequences are expansion and/or softening.Laboratory tests usually focus on expansion,while in the field, softening and spalling of material may be more important.

电力线宽带通信技术具有较多优势,但是低压电力线信道特性极为复杂,导致通信效果不能良好稳定。关于电力线宽带通信的可靠性和快速性的研究仍在发展当中,由于各国电网环境的差异较大,目前为止国际上尚未能形成统一的技术标准。我国的电力线信道特性也与国外不同,特别是早年对电网布线优化度重视不足及对电器质量要求较低,使得某些地区的信道条件相对恶劣。因此,低压电力线信道特性的合理检测和分析,对于我国电力线宽带通信标
随着电力线宽带通信技术的进一步发展和完善,在性能、可靠性和可管理性上有了巨大的提高; 国内技术机构通过引进、吸收先进技术,不断进行技术改造,使电力线宽带通信产品日趋成熟,国家相关部门也对该项技术开展检测、评估和验证。本文对电力线宽带技术检测和结果进行了深入分析,对外界环境温湿度、线路干扰、分支影响等方面进行检测、分析和研究。
