This decreases the device thickness and depletion voltage and consequently reduces material quality requirements and cost of the detector material.

这减少了设备的厚度和电压损耗，从而降低材料的质量要求和探测器的材料成本。

The overall cost of water scarcity—from pollution and the depletion of groundwater—is estimated to be 147 billion yuan ($21.4 billion) a year, or almost 1% of China’s annual output.

由于水污染和地下水消耗所带来的水资源不足的总体代价估计约为147亿人民币（21.4亿美元），大约是中国年度财政支出的1%。

In addition, the independents are allowed to take percentage depletion, while the integrated firms must use cost depletion.

In contrast to the depletion economics that drive up the cost of fossil fuels over the long run, solar power is a Silicon Valley-style energy resource: the more we make, the more we learn, innovate and lower the cost of the technology.
