潮汐能量

By using the equi-valent gravity wave assumptionof tidal waves, the interaction among the typical 2 days planetary wave,semidiurnal tide and 9.6 hours inertial-gravity waves are investigatedin detail.

利用潮汐波的等价重力波假设，讨论了2天行星波与半日潮及9.6 h惯性重力波的相互作用，三波相互作用时能量守恒。

Engineers have long fantasised about harnessing all that energy, and with climate change and energy security now pressing political problems, ministers are taking them seriously.

长期以来，工程师一直梦想利用潮汐的能量。

Shallow moonquakes are located at depth of about 50-220 km, they are strong but rare, and with high-frequency. Deep moonquakes are located at the depth of about 700-1150 km, and occur as clusters related with the tidal stress between the Earth and the Moon.

月震按震源深度分布分为浅源月震与深源月震，前者的震源深度大约为50~220km，释放的能量较大但发生次数较少，记录信号以高频成分为主；后者的震源深度大约为700~1150 km，并具丛集性，与潮汐应力有关。

Scientists have been examining the amount of energy found in a tidal pool in monthlong periods.

科学家在整月的期间审查在一个潮汐水池能量找到的相当数量。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
