The aggregate fragment length decreased with increasing stage of fibrosis (P < 0.0001).
随着纤维化分期的增加，总碎片长度降低（P<0.0001）。
The anchorage length of reinforcing bar embedded in lightweight concrete provided by "Specification for Design of lightweight Aggregate concrete Structure (JGJ12-99)" is safe.
按《轻骨料混凝土结构设计规程》JGJ12—99规程建议值进行锚固设计是偏于安全的。
