1·Impacted fracture means that one bone fragment is embedded into another bone fragment.

嵌入骨折是指一个骨头碎片嵌入到另一个骨头碎片。

2·Temperature impacted on the fracture stress and elastic modulus of the material obviously. Elevated temperature will lead to low fracture stress and smaller elastic modulus.

温度对断裂应力和弹性模量的影响也比较明显，高温会导致低的断裂应力和小的弹性模量。
