And on two previous occasions it has reduced the level of tax rebates that exporters of energy-intensive goods can claim, in some cases down to zero.
它已经两次降低能源密集型产品出口商能够申请的减免税额度，在一些商品中已降为零。
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。
Remember that depending upon how you define your zero level here, you also end up with negative values for potential energy.
记住这个值取决于，你怎么定义0水平，你的得到的势能，也是负值。
Only by these, can we improve the level of energy-efficient buildings and the target of which-non-pollution and zero energy consumption-will be achieved.
只有这样才能不断提高我国的建筑节能水平，促进建筑节能工作向着零污染、零消耗的目标大步迈进。
The result showed that the chemical reaction of microwave synthesizing nano-TiC is a zero level reaction, the kinetic equation of the reaction and the reaction's activation energy were confirmed.
结果表明，微波合成纳米碳化钛粉体的化学反应属零级反应，且确定了反应动力学方程及反应的活化能。
