• Find the magnitude of the average acceleration during the interval .
  求在这段时间间隔内平均加速度的数值。
• The sunny intervals we were promised have been few and far between .
  我们原可望能有几阵晴天，结果却很稀少。
• The individual particles are spread over an increasingly wide interval .
  各个粒子扩散到一个越来越宽的范围。
• The time interval between the shots depends on the degree of multiplicity .
  激发的时间间隔取决于叠加的程度。
• the domain of dependence is restricted to the interval 0≤x≤1.
  相关域限制为区间0x1。
• The integers divide the number line into infinitely many half-open intervals .
  整数把数轴分成无穷多个半开区间。
• We use nonparametric tests, we lose sharpness in estimating intervals .

• Intervals can be either real or imaginary in the theory of relativity .
  在相对论中，间隔可以是实数，也可以是虚数。
• Therefore, the results can be valid only for very short time intervals .
  因此，所得结果只能在很短的时间阶段中成立。
