Radioactive potassium-40 decays to argon-40 with a half-life of about 1.3 billion years, making this method useful for dating rocks that are billions of years old. A more sophisticated method, called argon-argon dating, provides a more accurate estimate of the original potassium-40 content by means of the ratio of argon-40 to argon-39 in the rock, thus yielding a more accurate age determination.

放射性钾-40衰变成放射性氩-40需要大约13亿年，因此使得该方法被用来测定10亿年以上的岩石的年龄。一种更为复杂的氩-氩年代测定法利用岩石中氩-40和氩-39的比值来测定原有的钾-40量以确定一个更加精确的数值。

An extra voltage, an overvoltage, is needed to send the current across the barrier. When the current is cut off, the overvoltage does not drop to zero immediately. Instead, it decays , allowing a current to flow for a short time.

我们需要一个超电压来传送一个能够通过电化学降的电流，当电流被断开后，超电压不会马上降到零位，而是衰减，电流还会在短时间内流动。

Thus, delivery pressure remains constant even as cylinder pressure decays , eliminating the need for frequent control knob adjustment.

因此，即使钢瓶压力下降，调整器的输出压力保持恒定，从而不需要经常调整控制钮。

In a single-stage regulator, delivery pressure increases as cylinder pressure decays , because there is less gas pressure exerted on the valve stem.

在单级调整器里，输出压力随钢瓶压力的减小而增大，这是因为施加在阀门系统上的气体压力减小了。

This fallout material decays over a long period of time, and is the main source of residual nuclear radiation.
