physical decay

Geometric and physical decay sources producing observed signal amplitude variations were sorted according to their physical mechanisms.

从产生接收信号振幅变化的机制出发，提出产生信号振幅变化的几何衰减和物理衰减两个不同的源。

The impact of velocity on the lifetime of unstable particles and physical clocks can be understood from the influence of their motion relative to the local dominant gravity field on the physical processes underlying particle decay and timekeeping of clocks.

不稳定粒子寿命和物理时钟受各自的运动状态影响，也可以分别由粒子衰变和物理时钟依赖的具体物理过程受其相对于局部优势引力场的运动状态的影响来解释。

Physical deterioration, e . g . wear and tear, erosion , rusting, rot and decay.

自然损耗, 例:磨损 、 生锈 、 腐朽和自然侵蚀.

The decay of the external scalar-field of a black hole is studied in the third chapter, i.e., the physical mechanism of the decay of neutral scalar-field in the gravitational collapse, and the physical mechanism of the decay of charged massive scalar-field in the gravitational collapse.

第四章主要研究有质量标量场在黑洞外部的衰减，即有质量中性标量场的真空量子极化，在黑洞时空背景中有质量荷电标量场的衰减。

your gift survived it all: The parish of rich women, physical decay, Yourself.

可是你的才赋却超越这一切：贵妇的教堂，肉体的衰颓，你自己；

Your physical body has also been permitted to decay.

你的肉体也被允许去衰败腐烂.
