灵敏度

A simple highly sensitive method for monitoring total tritium in air is described.

本文介绍一种简单、高灵敏度的空气中总氚量的监测方法。

In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

The L-form of tubercle bacillus can be detected by PCR technique and IK staining, with high positive rates and high sensitivity.

PCR技术及IK染色，检测抗酸菌L型的阳性率及灵敏度均较高。

The assay of serum TSGF is of high sensitivity and specificity. It is of great value in diagnosis and prognosis of malignant tum or patients.

TSGF检测具有灵敏度及特异度高等特点，有利于恶性肿瘤的诊断，对恶性肿瘤病人的病情和预后判断具有重要价值。

All in all, I have lost sensitvity in the centre speakers because they no longer give any mid range, but I have gained on the outer speakers because the mids there are less muddy and I have a properly functioning tweeter.

小结 总之，我失去了在该中心发言人灵敏度，因为他们不再提供任何范围中，但我有经验者外，因为有较少中频泥泞和我有一个正常运转的高音。
