Based on the principle of minimum stream power, a new method for designing stable channel is proposed.

基于最小能耗原理，本文提出了一种稳定渠道断面设计的新方法。

At upper flow regime, the total stream power gradually deviate the effective stream power from movable plane bed to existence of sand wave.

在高能态区，从动平整床面到沙浪的出现，总水流功率又逐渐背离有效水流功率。

So we actually believe that the hybrids have done their job in terms of pushing the technology on the main stream power trains which is a good thing.

所以，我们确信，该混合动力是通过推动主流的传动系统来工作的，这是一件好事。

But according to the authors of the latest research, 2013 could see a big breakthrough in tidal stream power.

And the Russians said, well all right, if the Iranians want to possess the whole, what's called the nuclear fuel cycle, that is, to have a guaranteed stream of nuclear fuel for power plants, which involves enriching uranium, we'll do it in conjunction with Iran, but in Russia.
