半径

• For a given radius no one angle is correct for all speeds .
  对于给定的曲率半径，没有一个适合所有速度的角度。
• It is now necessary to introduce a sign convention for radii of curvature .
  现在必须介绍曲率半径的正负号规则。
• Hence, the damage radii can not be determined from overpressure alone .
  因此，破坏半径不能单单由超压力大小来决定。
• The shock from the explosion crushed the rock to a radius of 130 feet .
  爆炸形成的冲击波把130英尺半径内的岩石捣碎。
• The particle radius unit, the micron, is especially common and useful .
  粒子半径的单位是微米，微米这个单位尤其普通和有用。
• The radii of the rings are determined by the spacing of the gravity observation points .
  圆的半径为重大观测点之间的距离所决定。
• The roche limit for the earth is a small fraction of the radius of the moon's orbit .
  地球的洛希极限相当于月球轨道半径的一小部分。
• A drop zero radius would require an infinite supersaturation to maintain it .
  要使一个半径为零的液滴保持下去将需要无限大的过饱和度。
• In the alternate approach, the burning rate is expressed as a function of drop radius .
  在另一种方法中，燃烧速率表示为液滴半径的函数。
• The compliance-calibration specimen has a slot of finite-tip radius in place of a crack .
  柔度算定试样是用一个有限端部半径的槽来代替裂纹。
