吸光度

Wistar rats were randomly divided into normal group, sham-operation group, 4 weeks diabetes mellitus model group (M4), 6 weeks diabetes mellitus model group (M6) and 8 weeks diabetes mellitus model group (M8). Behaviour was tested with Morris water maze and shuttle box test.

穿梭箱实验、Morris水迷宫实验检测大鼠认知行为学改变，免疫组织化学法、免疫印迹法、RT-PCR和酶联免疫吸附法检测BACE1；ELISA法检测Aβ在糖尿病大鼠脑组织中的表达，用图像分析仪测定吸光度值。

Methods:Expression of PPAR-γ in 15 cases of non-cancerous lung tissues and 64 cases of lung cancer tissues was detected by using immunohistochemistry. The average A values were measured by using image analysis. The expression of PPAR-γ in lung cancer cells was detected by using RT-PCR.

方法以免疫组化的方法分别检测15例非癌肺组织和64例肺癌组织中PPAR-γ的表达，并通过图像分析测各组的平均吸光度值。

Due to N-N bond weakest, nitrosamines are denitrosated by HBr/HOAc to release nitrogen oxide, which can be oxidized to form NO〓. Trapped in sulphanilamide and N-1naphthylethylene diamine di-HCl solution, the NO〓 transforms into NO〓 and develops color in the solution.

该法根据亚硝基官能团中N-NO键的键能最低，采用氢溴酸/醋酸溶液选择性断裂N-N键，对逸出的NO通过氧化成为NO〓然后用显色剂吸收，再由分光光度计测量吸光度并计算出亚硝胺含量。

The industrial magnesia and vitriol are used to produce magnesium sulfate in this paper, and the simulated wastewater is prepared using magnesium sulfate and kaolin. The flocculating effect of polyacrylamide, cationic polyacrylamide and anionic polyacrylamide is studied and compared through measurement of absorbency by spectrophotometer.

利用工业氧化镁和硫酸制备一定浓度的硫酸镁，结合高岭土配制氧化镁烟气脱硫的模拟废水，通过分光光度计吸光度测定了聚丙烯酰胺、阳离子型聚丙烯酰胺和阴离子型聚丙烯酰胺在模拟废水中的絮凝效果。

A way to improve the solubility of straight chain starch was adopted and the best added quantity of starch was found.

随着直链淀粉质量浓度增大，HPAM溶液的最大吸光度也在增加。

The results show that the Abs not only increases with the increase of HPAM mass concentration, but also with the increase of straight chain starch mass concentration.

实验发现溶液吸光度不仅受聚丙烯酰胺质量浓度的影响，而且也受淀粉质量浓度影响。

An improved assay of LMIF has been developed and that a model of conditioned LMIF response in vitro has been established.

本工作建立了稳定的LMIF吸光度检测法，建立了环磷酰胺条件性抑制LMIF的模型。

The procedures of conditioned response and DTH response were same as before except for the LMIF preparation.

LMIF测定是以间接毛细管方法结合分光光度计，测定游出细胞的吸光度。

In this paper,an absorbance ratio-derivative method for the simultaneous determinaton of mercury and lead has been developed.

提出了运用吸光度比值-导数光谱同时测定Hg2+和Pb2+的新方法。

The absorbance of MTT and PCNA in hypoxia group were higher than in normal group.

结果表明，低氧组周细胞的MTT和PCNA吸光度均较常氧组高。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
