One shortcoming of these beams is that they typically have a range of energy, caused by the gradual rise of laser power from zero to its maximum level.

但它的一个缺点就是，激光功率从零升到最大值的过程，会使粒子或X射线束具有一定的能谱分布。

The kinetic energy criterion more effectively represents the model stability in steady flow simulations than the maximum water level variations or the residual mass criterion.

在恒定流计算过程中采用动能标准比最大水位修正和剩余质量标准更能有效地判别模型的稳定性。
