The conclusions are: The sonic velocity determined by the material's properties is the upper limit of the crack velocity; Bridging fibers plays a key role in increasing the composite's toughness and stopping the crack's propagation; The semi-infinite crack propagating in infinite region with the fiber bridging traction action is equal to the semi-infinite crack propagating in strip.

结论有：(1)由材料性能决定的音速是裂纹传播速度的上限；(2)桥联纤维在增韧复合材料和组织裂纹扩展中起了关键作用；(3)受桥联纤维力作用的半无限长裂纹在无限域中扩展等效于半无限长裂纹在带域中扩展。

Methods In the study,experimental animals were divided into three groups. Thiamazole was used to replicate the model of maternal pregnant hypothyroidism. The infant rats were innate hypothyroidism. T4 substitution group rats were administrated with T4 from postnatal 0 day as well as the same days normal neonatal rats as control. TdT-mediated dUTP nick end labeling was carried out to detect the positive cells of PCD in cortex and hippocampus of postnatal 7,14 and 21 days rats. Immunohistochemical staining technique was employed to detect Bcl-2 and Bax proteins in relevant sections. Experimental data were statistically analysed by One-Way ANOVA, SNK-q test and Spearman rank correlation analysis.
