physical decay

基本解釋

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 constant of electrostatic charge decay time is an important physical quantity that can describe the electrostatics property of materials.
靜電衰減時(shí)間常數(shù)是定量描述材料靜電性能的重要物理量。
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(duì)已經(jīng)出版的同位素的數(shù)據(jù)時(shí)，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(gè)速率被物理學(xué)家假定是一個(gè)物理常量。

The physical decay is evident and these areas suffer all the social problems associated with inner-city poverty.

Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation.
