Optical coupling state between the read-out beam and the optical waveguide can be judged by analyzing the emission pattern from the MWH-ROM.

而且，通过分析波导射出端的强度图形，可判断读出光和光波导的耦合状态。

Information recorded in different layers of the MWH-ROM was reconstructed without any crosstalk effects from other layers by adjusting the position of the read-out beam.

通过读出光的位置重合，可读出各个记录层所记录的信息，而不受其他层的影响。

That compares with $50-70 per MWh for onshore wind power in America, by the IEA’s reckoning, and even lower prices for power from fossil fuels, unless taxes on greenhouse-gas emissions are included.

据国际能源署估算，与之形成对比的是美国的近海风力发电，成本为50-70美元/千瓦时，而化石燃料发电如果不算温室气体排放税的话，价格更低。
