TRNGs are usually based on physical phenomena such as thermal noise, atmospheric noise, radioactive decay and even coin-tossing.(真隨機(jī)數(shù)發(fā)生器的熵源通常來自于真實(shí)的物理世界，如熱噪聲，大氣噪聲，放射性衰減甚至擲硬幣。)

The constant of electrostatic charge decay time is a important physical quantity that can describe the electrostatics property of materials.(靜電衰減時間常數(shù)是定量描述材料靜電性能的重要物理量，可以通過測量靜電電荷衰減時間達(dá)到測量靜電的目的。)

Quantum tunneling is involved in many physical processes, such as radioactive decay and the nuclear fusion that takes place in the Sun.(量子隧穿發(fā)生在許多的物理過程中，比如說放射性衰變和太陽上發(fā)生的核聚變。)

The physical Earth is now in a rapid state of decay and is running on its programmed systems.(地球上有很多區(qū)域有溫泉，但其中一些根本不是自然形成的。)

As the researchers pored through published data on specific isotopes, they found disagreement in the measured decay rates - odd for supposed physical constants.(當(dāng)研究者核對已經(jīng)出版的同位素的數(shù)據(jù)時，他們發(fā)現(xiàn)查到的值和測量到的衰變速率不一致，而這個速率被物理學(xué)家假定是一個物理常量。)

You might say, "Look, the physicalist can't tell us that, because all the physical parts are still there when you've got the corpse, at least if it's a fresh corpse before the decay has set in."(你可能會說，你看，物理主義不會告訴我們那些的，因?yàn)槭w所有的，身體器官部分都還存在，至少對于還未腐爛的尸體而言是這樣的。)
