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。
The coding used to impress information on the wave can be a function of the frequency (the number of waves or cycles per second) or amplitude of the waves or cycles.
对载波中的信息进行压缩的编码方式可以是载波或周期的频率调制或振幅调制。
