拉伸应变

The measured parameters including the changes of prevertebral height, the changes of anterior longitudinal ligament strain and the changes of vertebral disc's height; segments including upward and downward of the fractured vertebral bodies were observed.

标本分组，并分别在过伸牵拉、纵向牵引、器械加压三种方式下复位，观察椎前高度、前纵韧带应变值、伤椎上下椎间隙高度的变化。

Uniaxial tensile behavior of nickel foam under four different strain rales and four different temperature levels separately is studied.

研究了泡沫镍分别在四种不同应变率和四种不同温度下的单轴拉伸行为。

Using dual energy X-ray bone density instrument XR-36 model to detect the bone mineral density of the left femur of the rats. Using the strain test system, we examined the biomechanics index according the tension and three-spot bending test; we also examined the bone calcium of the lumbar vertebra through plasma emission spectroscopy . We examined the serum calcium and magnesium by using the nomal biomechanics method,and examined the serum acid phosphatase and osteocalcin by using the Elisa method.
