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。
We could say an energy level diagram 0 This would be energy. Here is zero.
我们可以画一个能量图,这是能量，这里是。
As the Australian Rainforest Information Centre points out, these are the ultimate in low-cost, low-maintenance, zero-energy homes.
正如澳大利亚热带雨林信息中心认为的那样，这样的房子才是低成本、低保养、零耗能房屋的终结。
We could put the energy, the zero of energy there.
我们可以把能量零点放在能量最低的状态这里。
Drying in the wind and sunlight, rather than a dryer, USES zero energy.
