So, for example, if we were looking at the actual wave function, we would say that these parts here have a positive amplitude, and in here we have a negative amplitude.

我们看，一个波函数，我们说，它这部分幅值，为正，这部分幅值为负，当我们看。

The variation of R wave amplitude has little relation with cardiac output, heart pumping function, especially with pulmonary wedge pressure.

波振幅的改变与心输出量及心脏的泵血功能，尤其是肺动脉楔压之间无明显关系。

It is pointed out that the wave function of system can be exactly solved if the perturbation only depends on the time, and the exact expression of transition probability amplitude can be obtained.

本文通过计算指出，若微扰只与时间有关，则体系的波函数可以精确求解，从而得到跃迁概率振幅的精确表达式。

So again, if we think of a graph of the wave function, we had the wave function is at its highest amplitude when it's lined up with the nucleus, and then as we got further away from the nucleus, the amplitude of the wave function ends up tapering off until it never hits zero exactly, but it goes down very low.

同样，如果我们想象一幅波函数的图，波函数在原子核的位置上,有着最高的振幅，随着与原子核距离变远，波函数振幅逐渐变小直到,它永远不会到零，但它会变得很小。
