N the difference between apparent solar time and mean solar time, being at a maximum in February (over 14 minutes) and November (over 16 minutes) 时差
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。
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。
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。
So, for example, if we're to hold the time constant, this makes it a lot simpler of an equation, because what we can end up doing is actually crossing out this whole term here.
比如说,如果我们把时间,定为常数,这使得方程,大大简化,因为我们可以把,这一项划掉。
You can go ahead and use that equation, or you could figure it out every time, because if you know the total number of nodes, and you know the angular node number, then you know how many nodes you're going to have left.
你们可以直接用这个方程,或者每次都自己算出来,因为如果你们知道了总的节点数,又知道角向节点数,就知道剩下的节点数是多少。
Some will be growing very rapidly, some will be growing less rapidly, and what this equation shows you here or that rate of growth the to the doubling time of cells.
有些会生长得更快些,有的慢一些,而这个方程告诉你,即生长的速率和细胞倍增的时间联系起来
