Piezoresistivity of ECAC may involve proximity effect, microcrack and the staggered arrangements of conductive pass-ways due to shear strength of aggregates.

压敏产生的原因是导电沥青混凝土试件的压缩邻近效应、微裂纹和石料间的剪切力使部分导电通路错位。

Bad weather, such as the heavy summer rains, after drouth, which saturate ploughed soil, reduce soil shear strength, facilitate masse soil movement, and instigate gullying.

恶劣的气候条件，比如久旱之后的夏季强降雨，使土壤耕地饱和，降低土壤切变力，容易使土壤移动，形成冲沟。
