当共晶试样增速和减速的加速度值相同时，实际共晶生长速度的变化过程呈对称的逆曲线。

The variation curves of the eutectic growth rates are approximately symmetric for the increase and decrease in the displacement velocity at the same acceleration.

研究报告说，如果妇女运动提高女性期望值的速度高于社会满足她们期望值的速度，那么她们将更有可能对实际经历的生活感到失望。

"If the women's movement raised women's expectations faster than society was able to meet them," the paper says, "they would be more likely to be disappointed by their actual experienced lives."
