The fading correction and its corresponding calculation method were specially introduced in this paper for improving the accuracy of the environment cumulate kerma.

了提高环境累积比释动的测量准确度，特别介绍了环境剂量计的衰退修正及其计算方法。

The Air Kerma Rate of 125I sources is determined by the well-type ionization chamber.Thereafter the apparent activity of 125I sources is calculated and measured results are anylyzed.

采用井型电离室测定125I粒子源的空比释动率，进而估算出125I粒子源的表观活度（又称等效活度），并对结果进行了分析。

The corotation circle acts as an interface that can either reflect or transmit these waves, allowing them to gain energy at the expense of the global rotational kinetic energy of the galaxy.

共同旋转圈的作用，像个可以反射或透射这些波的介面，让它们转换星系整体的转动动身的量。
