查询词典 detection

Under the optimum conditions, the analytes could be separated within 17 min in a 75 cm length capillary at a separation voltage of 18 kV in a 10 mmol/L borate buffer (pH 8.2). A 300 μm diameter carbon disk electrode generated a good response at+ 0.95 V vs. saturated calomel electrode (SCE for all analytes. The relationship between peak currents and analyte concentrations was linear over about three orders of magnitude with detection limits (S/N=3) ranging from 78 μg/L to 110 μg/L for all analytes.

在优化的实验条件下，以直径300μm的碳圆盘电极为工作电极，检测电位为＋0.95V，在10mmol/L硼酸盐(pH8.2)的运行缓冲溶液中，上述6种活性成分能在17min内实现很好的基线分离，被测物浓度与峰电流在3个数量级范围呈良好的线性关系，检出限(S/N=3)范围为78~110μg/L。

Aturated calomel electrode, the calibration curves for all polycarboxylic acids studied were linear with 2～3-orders of magnitude and all the detection limits (s/n=3) were below 15 fmol except malonic acid.

CE获得了选择性的、灵敏的检测，检测限在15fmol(丙二酸97.5fmol)以下，线性范围达2～3数量级。

Concerning the detection of weak speech signal in stronger noise background, an effective modified model based on Simulink and FDATool is proposed. The model is composed of double bandpass digital filter and traditional adaptive noise canceler.

针对强噪声背景中语音信号提取的难度，提出一种基于Simulink和FDATool的改进型信号提取模型，该模型在传统自适应噪声消除器SIMULINK模型的基础上通过增加双带通数字滤波器实现。

The general principle of RR STAP is addressed in this paper with the result that the output signal to clutter plus noise ratio will be probably near as or even better than that of full rank STAP. Thereby, the final detection performance of practical airborne phased array radar won't necessarily be degraded when rank reduction is operated properly. There exists two basic types of adaptive processor, one is Direct Form Processor and the other is Generalized Sidelobe Canceler .

降维可以在空域、时域或时空联合域进行，无论在哪个域内进行，都可以等效成对全空时数据矢量施以一个降维变换矩阵Q〓，如果Q〓与数据的特征结构无关，那么这类降维处理器的结构预先也是固定的，如果Q〓与数据的特征结构有关，即STAP在特征子空间内进行，那么所选择的子空间不同，STAP性能也不一样。

Abnormal expressions of Ki67 and PTEN protein were associated with canceration in stomach. Therefore, both of them may act as useful biomarkers for early detection of gastric carcinoma.

Ki67和PTEN蛋白的表达异常与胃癌的癌变过程相关，两者有可能成为胃组织早期癌变的分子标记物。

Combined detection of NDRG1 and E-cadberm can be used to predict the metastasis of liver in colorectal caner.

NDRG1、E-cadherin联合检测，可作为预测大肠癌肝转移的有用指标。
