When the crystal size is about three nanometers (billionths of a meter), the material has its ultra-strong and ductile characteristics.

当晶体大小大约为3纳米（1纳米等于10亿分之一米）时，天然丝材料具有超强的强度与延展性特征。

Lord Carloway pointed out that evidence in the case showed Transco was aware by 1988 that within a decade of being laid ductile iron mains could corrode in adverse soil conditions and the problem had been highlighted by fatal blasts at Warrington and Ilkeston.
