MEANING OF 衰变
衰变 (衰變)
radioactive decay

EXAMPLE SENTENCES

用二进制数对递次衰变链的衰变路径进行编码。

The decay pathways in successive decay chain were coded with binary digits.

43号元素的衰变速度非常快。

但是普渡大学的一组研究者用意想不到的方式挑战了衰变速率恒定这个假设。相比于原子核衰变,他们对随机数更感兴趣。

But that assumption was challenged in an unexpected way by a group of researchers from Purdue University who at the time were more interested in random Numbers than nuclear decay.

系统的响应时间是毫微秒量级的,测量得到的衰变曲线是溶液的真实衰变曲线与仪器响应函数卷积的结果。

The response time of the system was in the order of nanoseconds. The observed fluorescence decay curves were convolutional results of the real decay curves and the instrumental response curve.

无意义介导的衰变检查是否存在过早的无意义密码子。

Nonsense-mediated decay checks for the presence of premature nonsense codons.

这项实验的关键因素在于放射性衰变是一个量子过程。

The point of the experiment is that radioactive decay is a quantum process.

它一旦从分裂的铀中产生,就会很快衰变

It's just that once was generated from split Uranium, it decayed very quickly.

退化,衰变;[递]降[分]解,裂解;降低[品质];压降。

To lower in quality or character; debase.

仪器有核衰变修正、扣除本底和自动检测故障的功能。
