Factors influencing precise measurement of relative peak counting rates are discussed in time-series measurements over a dynamic range of 1000-fold radioactive intensities (10 half-lives).

对放射性强度跨越1000倍动态范围(10个半衰期)的跟踪测量中影响相对峰计数率精确测定的因素进行了讨论。

The influences of the series connection seperation equipment on the overflow flux and sediments half-content diameter D50 were studied by orthogonal test, range analysis and variance analysis.

考虑试验因素对溢流量和溢流中粒径D50影响程度的大小以及它们在分离中所起作用的大小，优化了串联分离设备参数：旋流入口压力为0。
