查询词典 density

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.

The effects of air density,the solution's viscosity,the surface tension and density on optimum vibration frequency were analyzed.

分析了空气密度、胶液粘度、胶液表面张力和胶液密度对最优振动频率的影响。

Air density's effect is very little, however, optimum vibration frequency decreases with the solution's viscosity increasing, and increases with the solution's surface tension and the solution's density increasing.

结果表明，空气密度对频率影响很小，最优振动频率随胶液粘度的增大而减小，随胶液表面张力和胶液密度的增大而增大。
