AbuBakr Bahaj, in charge of the Southampton research, said: The prospects for energy from tidal currents are far better than from wind because the flows of water are predictable and constant.

负责南安普顿研究的 AbuBakr Bahaj 说：潮汐流的能源前景比风能要好得多，因为水流是可预测和恒定的。

Constant variations in the amount of sunlight available on Earth at any given location make energy storage a necessary design feature of terrestrial solar-energy systems.

在地球上任何一个特定地点，阳光的不断变化使能量储存成为地球太阳能系统的一个必要设计特征。

We can also figure out the energy of this orbital here, and the energy is equal to the Rydberg constant.

我们还可以在这里计算出该轨道的能量，该能量等于里德堡常数。

And that is that the lattice energy as is depicted by the Madelung constant is dominant.

如晶格能中的马德隆常数,就十分重要。

Whereas under these conditions, these quantities, if you look at free energy change, for example at constant temperature and pressure, H you can still calculate H.

但是，在这些条件下，这些物理量，如果我们考察自由能的变化,例如在恒定的温度和压强下，我们仍然可以计算。

So now we have that energy is equal to the negative of the Rydberg constant divided by n squared.

我们可以把能量方程大大简化,现在能量等于负的Rydberg常数除以n平方。

The expansion has been sturdy rather than fragile, growing steadily since the June 2003 tax cut despite hurricanes, rate hikes, expensive energy and constant talk of a consumer slump.

That's because meeting global energy needs requires constant investment on a scale unmatchable by economically uncompetitive sources like solar, wind and biofuels.

FORBES: CERA Week

In conclusion, incoming energy throughout the year is constant, with no large variations, and humidity controls the balance of this energy between sublimation and melting.
