The results of residues demonstrated that cyhalothrin in cotton seed is less than the minimum detection limit of t he present method. 最终残留量的测定结果说明,氯氟氰菊酯在棉籽中无残留。
The detection of moving nuclear material is more difficult than that of static one (namely, the minimum detectable limit of moving nuclear material is lower than that of static one). 从定性的角度易知，由于核材料移动时比静止时的探测下限低而更难以探测。
For 51Cr, 60Co, 65Zn, 95Zr-95Nb and 137Cs the decontamination factor is greater than 103. The minimum detectable limit of this method is 3. 8X 10-3 Bq/L. 对铬-51、钴-60、锌-65、锆-95-铌-95和铯-137等核素的去污系数均大于10~3。方法简便;易于操作;探测限为3.;8×10~(-3)BqL~(-1)。
From the qualitative point of view, the nuclear material are more difficult to detect when moving than static (namely, the minimum detectable limit is lower when static than moving). 从定性的角度看，核材料移动比静止时更难以探测（即静止比移动时的探测下限低）。
The minimum detectable limit of the nuclear radiation detector array is an important technic criteria to judge whether the detector satisfies the detecting requirements or not. 摘要核辐射探测器阵列的探测下限是判断其是否符合探测要求的重要技术指标。
