1·Another thing we will need is the equation of time. Here is the formula for that.

另一件事，我们会需要的是方程的时候，这里是公式。

2·The Schrodinger equation of time - dependent harmonic oscillator is solved by the time space transformation, and its application in physics is presented.

利用时空变换法求解含时谐振子的薛定谔方程，并对这类问题在物理上的应用作了说明。

3·A helix equation of time-varying pitch is established, revolving elliptic cylinder as equal angular velocity and rising as variable velocity at the same time.

建立了绕椭圆柱面以等角速度旋转，又以变速度上升的非定常螺距的螺旋线方程。

4·The conclusion shows that the optimal strategy of predator is the quadratic equation of time and the profit is the descending function of temporary impact coefficient.

结论表明，捕食者的最优交易策略为时间的二次曲线形式，并且捕食交易利润是瞬时冲击系数的单调减函数。

5·It's self winding, has a minute repeater, perpetual calendar, equation of time, jumping hour, power reserve indicator, and a bimetallic thermometer - everything but MMS messaging.

它可以自动上弦，具有三问报时、万年历、时差设置以及跳时功能，另外还配有动力储备指示器和双金属温度计——除了MMS彩信功能什么都有的。

6·And so we're going to take the derivative versus time of this equation.

我们要求这个，方程的时间导数。

7·There's one more equation that I wanted to write down ... and I'm going to not-- I'm not going to spend a lot of time explaining this because it's going to take awhile.

这里我想再写一个等式,当然我不会-,我不会花太多的时间解释这个,因为要花太长时间。

8·That's the picture of one equation at a time.

这种图一次只有一个方程序。

9·Yes, I divide... m Oh, there's an m here, m And now what I'm going to do, I'm going to take the time derivative of this equation.

对，我除以。，哦，这里有个，应该在这里。，and, the, m, has, to, be, here。，现在我要做的，我将把这个等式，转化成与时间有关。

10·But let's not bother.Again, what this equation tells you is that if the magnetic field changes over time then it creates, just out of nowhere, and electric field.

我们就不纠结这种情况了，这个方程告诉你，如果磁场随时间变化，它就会无中生有地产生电场。
