Keeping slip frequency constant we can get nearly constant torque output characteristic.

维持滑差频率不变，就可获得近似于恒定转矩的输出特性。

The stator flux-oriented vector controlling strategies of keeping stator frequency constant and capturing the maximum wind power are verified by experiment results.

实验结果验证了定子磁链定向的矢量控制策略既能保证定子输出频率恒定，又能较好地跟踪风力机的最大功率输出。

So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.

所以这意味着转移到电子,上的能量也越大，但这并不是，我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。

What Einstein then clarified for us was that we could also be talking about energies, and he described the relationship between frequency and energy that they're proportional, if you want to know the energy, you just multiply the frequency by Planck's constant.

爱因斯坦阐述的是我们,也可以从能量的角度来谈论，他描述频率和能量之间的关系,是成比例的，如果希望知道能量值，你用普朗克常数乘以频率就可以了。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。

The reason why this ends up being a secure system, says Amento, is because from person to person, the frequency of the sound remains constant.
