For supercooling directional solidification, ideal directional microstructure can be obtained only within the supercooling range 63～83K and 127～170K. These two supercooling ranges just corresponds to the supercooling for developed equiaxial dendrites in ordinary supercooling solidification.

6对于深过冷定向凝固来说，只有在63～83K的低过冷度范围和127～170K的中过冷度范围才能获得理想的定向生长组织，而这两个过冷度范围正好对应于深过冷熔体凝固组织为发达的等轴枝晶的过冷度范围，这种组织的相似性似乎与过冷度一样具有遗传性。

The thickness of bovine liver in vitro ranged from 4 to 10 cm. Ultrasound energy was continuously delivered to ablate the liver with a frequency of 1.6MHz, and spatial peak pulse average acoustic intensity of 12000 W/cm^2. The characteristics of complete coagulation necrosis and exposure time were measured after FUSC exposure, and pathological changes in treated bovine liver tissue were observed.

All the animals were divided into 3 groups of 21 each randomly: 1 Kirschner wire group: Intramedullary Kirschner wires were made as inner fixation. 2 CPC group: Injectable CPC single was injected into medullar through 9# needle. The fracture parts were holded by hands until CPC harden. 3 CPC-BMP group: treated as CPC group but substituted the composite of CPC/rhBMP-2 for CPC.
