查询词典 sensitivity analysis

In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了将压电晶体谐振器用作定量测量质量的装置，并从理论上导出了频率与质量变化之间的关系式——Sauerbrey方程：ΔF=〓=-。。。

Resultsthe level cross-sectional area of the median nerve at the pisiform bone in the cts patients of the observation group was significantly higher than that of the normal control group and the flat rate of the observation group was significantly higher than that of the normal control group. the high-frequency ultrasound diagnostic sensitivity was 80.4%(lower than the sensitivity of the conventional electrophysiological examination),with painless,non-invasive characteristics of dynamic ultrasound imaging and lower cost.

The results showed that in evaluation of the method by detecting 50 RHD 1227A positive and 50 RHD 1227A negative individuals, the genotyping method displayed a sensitivity of 100% and a specificity of 100%; in evaluation of the method by detecting 33 DEL positive and 89 DEL negative individuals, the sensitivity was 100%, however, there were two serologically negative samples which were confirmed as positive using genotyping method.

结果表明：在50例RHD 1227A阳性和50例RHD 1227A阴性的Rh阴性样本中基因分型方法的灵敏度和特异性都是100％；在33例DEL阳性样本和89例DEL阴性的样本中，基因分型方法的灵敏度为100％，有2例样本血清学结果为阴性而基因分型结果为阳性，重新用血清学方法和序列分析方法复核这2例样本，发现2例都是血清学漏检，因而基因分型方法的特异性是100％。

Moreover, supersensitization as well as its mechanism by stabilizers is studied in spectral-sensitized AgCl emulsion Results indicate that the adding order of stabilizer and sensitizing dye has great influence on the sensitivity of emulsion and only stabilizer added after sensitizing dye can supersensitization be obtained Apart from supersensitization and fog-inhibition by stabilizers, it is also significant to spread the amount of addition of dye, which can lead the further improvement of sensitivity of emulsion.

本文还研究了稳定剂在氯化银乳剂中的超增感作用并应用多种手段研究了其超增感作用机理。结果说明，稳定剂与增感染料的添加次序对乳剂感光度有非常重要的影响，只有在增感染料之后加才可能产生增感作用。在一定的稳定剂添加范围内，它不仅可以提高氯化银乳剂的感光度、降低灰雾，而且还能加大增感染料的用量，进一步提高乳剂的感光度。这对乳剂的光谱增感来说具有重要意义。
