1·The relative consumption rate (RCR) and the approximate digestibility (AD) increased with the leaf age.

随着叶片日龄的增加，相对取食量和近似消化率有明显增大。

2·The wear and adhered tin masses were given out for the first time, and finally the measures decreasing the adhered tin and improving the wear resistance of RCR were put forward.

最后提出了减轻和控制软熔导电辊粘锡以及提高软熔导电辊耐磨性的对策。

3·RCR specimen maintained their integrity and exhibited a ductile failure under compression indicating that the toughness of concrete was improved by the incorporation of waste tire rubber.

碾压橡胶混凝土试件破坏时仍能保持其完整性，表现出明显的延性破坏特征，表明橡胶粉的掺入使得混凝土的韧性得到增强。
