您要查找的是不是：
- no detectable activity 未能检出活性
- There were no detectable alloantibodies by flow cytometry. 采用流式细胞计量术未检测到同种异体抗体的存在。
- Otherwise it has no detectable effect on the program output. 除此之外，在程序的输出上没有可察觉的影响。
- NF3-specific detectors are highly recommended since NF3 has no detectable odor. 由于NF3没有可探测到的气味，强烈推荐使用NF3专用探测器。
- Meaning that - for now - there's no detectable sign of cancer in my body. 这意味着至少目前我体内还没有癌症的迹象。
- Class A sludge contains no detectable pathogens and can be used anywhere. 类有机污泥不含检测得出的病媒，任何地方都能使用。
- NF3 has no detectable odor, so forced air/exhaust ventilation and ambient air monitoring are recommended where NF3 is stored or used. NF3没有可以探测到的气味，所以推荐在储存和或使用NF3的地方采用强迫通风/排气通风。
- There is no detectable "Garou gene," and DNA-testing does not reveal anything amiss. “狼人基因”是无法被检验出来的，DNA测试对此也无可奈何。
- No detectable amounts of fomesafen residues were found in stems, leaves, shells and seeds at harvest time. 对收获后采集的植株、果实（壳）和土壤进行分析测定，均未检测出氟磺胺草醚。
- Definition of 0 ppm is no detectable leakage registered on our organic vapor analyzer which has a range of 1-10,000 ppm. 在我们的组合气体分析仪（测量范围为1-10,000/百万）上没有泄漏显示。
- The result shows that the paclitaxe content is 0.0105% in Taxus media while no detectable content in Taxus chinensis var. mairei. 结果表明：曼地亚红豆杉枝叶中紫杉醇含量为0.;0105%25，而南方红豆杉枝叶中紫杉醇则没有检出。
- The dots change colour when they detect active versions of the genes. 当被探测的基因有了活性变化时,这些点的颜色就会发生改变。
- Intelligence detects activity near blast site that may augur a second nuclear explosion. 美情报机构在朝鲜核爆炸地点附近检测到活动,可能预示着朝鲜还将进行一次核爆炸。
- U.S. intelligence detects activity near blast site that may augur a second nuclear explosion. 美情报机构在朝鲜核爆炸地点附近检测到活动，可能预示着朝鲜还将进行一次核爆炸。
- The positive rates of cytoplasmic ER(ERc), ERn (nucleus ER),PgRc and PgRn were 0,6. 1%,12.1% and 63. 3% respectively. Most of the tumor samples had no detectable ER. 脑膜瘤性激素受体的阳性率:EK_c为0;ER_n为6.;1%25;PR_c为12
- By contrast, in cells cultured in simulated weightlessness environment, no detectable release of PGE 2 was found with the treatment of 0.5 Pa FSS (P<0.01). 而在一定的剪切应力范围内 ( 0 .;51
- No detectable grain coarsening was revealed near the SBs observed by EBSD and TEM, which means there is no inevitable relationship between formation of SBs and grain coarsening. 使用EBSD和TEM对剪切带附近进行观察，没有发现晶粒长大，这意味着剪切带的形成与晶粒粗化没有必然的联系。
- minimal detectable activity (MDA) 最低检出放射性强度
- Abdominal radiographs were obtained in 5 patients, with features of high obstruction in 2, a gasless abdomen in 1, and no detectable abnormality in the remaining 2. 5例病人做了腹部X线检查，其中2例有高位梗阻特征，1例为无气腹腔，其余2例没有发现异常。
- minimum detectable activity (MDA) [化] 最小检出量; 最小可检出放射性量; 最低检出量; 最低可检出放射性量
