2Examine the chromatograms of the solutions to be examined in the assay. The two principal peaks in the chromatogram obtained with the test solution are similar in retention time to the principal peak in the chromatogram obtained with reference solutions of Estrone Sodium Sulfate and Equilin Sodium Sulfate.

在含量测定项下记录的色谱图中，供试品溶液两个主峰的保留时间应分别与对照品中雌酮硫酸钠和马烯雌酮硫酸钠峰的保留时间一致。

The experimental results show thatβ-MnO_2 nanorods has the highest activity among them and allows the decoloration degree of the fuchsin acid solution to reach 97.6% within 60 minutes.

以所制备的纳米结构锰氧化物为催化剂，研究了它们对H_2O_2氧化降解酸性品红模拟废水的催化性能。其中β-MnO_2纳米棒的催化活性最高，反应60min后酸性品红脱色率即达到97.6％。

Therefore, all the red, blue and purple and pink, magenta separations film should have a deep black.

因此，所有的赤色、蓝紫色和品赤色，在品赤的分色胶片上都不该有很深的不白色。

objectiveto analyze the total content of flavonoids in nigella glandulifera preyn et sint by colorimetric method.methodsrutin was used as reference substance and the detection wavelength was 500 nm.

目的采用比色法测定维吾尔药黑种草子中总黄酮的含量。方法以芦丁作对照品，以亚硝酸钠-硝酸铝-氢氧化钠体系为显色剂，检测波长为500 nm。

Make use of HPLC, can availably classify true or false D-calcium pantothenate, the D-calcium pantothenate sample diagram and standard diagram have similar diagram in same reservation time, the content meets provision;The false D is mainly depend on adding calcium inorganic salt, urea and glucose etc, to make specific optical rotation, calcium content, nitrogen content to attain a nation standard, but these material in the same reserve time have never absorbed diagram to make peak area very small, the content of external standard be low.

本文以市售D-泛酸钙为样品(山东新发药业有限公司生产)，对所建立的检测方法进行了验证，通过精密度、准确度和标准曲线等验证项目的实验，结果表明，本文所建立的D-泛酸钙的高效液相色谱检测方法可以准确地检测产品的含量；利用液相色谱图谱，可以有效地区分真假D-泛酸钙，D-泛酸钙样品图谱与标准品图谱在相同的保留时间处，有类似谱图，含量符合规定；搀假的泛酸钙主要靠添加无机钙盐、尿素和葡萄糖等使比旋度、钙含量、氮含量达到国家标准，但这些物质在此处无谱图造成峰面积很小，外标含量低。

This paper means to make comparison research in fingerprint chromatogram of raw and concocted Pinellia ternate by HPLC.

该实验旨在用高效液相色谱法对半夏的生品及其炮制品的指纹图谱进行比较研究。

The content of uncaria alkaloid in rhynchophylline was 0.71% measured by ultraviolet spectrophotometry at 246.0 nm wavelength.

结果：本品定性鉴定薄层色谱特征明显，与标准品有相同的Rf；紫外分光光度法在246.0 nm波长处测得钩藤总碱中钩藤碱的含量为0.71%。

Results:tlc characteristic of qualtative identification of this goods was apparent,with the same rf to standard samples.the content of uncaria alkaloid in rhynchophylline was 0.71% measured by ultraviolet spectrophotometry at 246.0 nm wavelength.conclusion:this method was found to be rapid,simple,economic,accurate and reproducible.

结果：本品定性鉴定薄层色谱特征明显，与标准品有相同的rf；紫外分光光度法在246.0 nm波长处测得钩藤总碱中钩藤碱的含量为0.71%。结论：此方法快速、简便、经济、准确、重现性好。

According to stipulations under each type, precisely weigh reference substances and test samples to formulate solutions, and then precisely size a certain amount to inject into instrument and record chromatograph chart.

按各品种项下的规定，精密称取对照品和供试品，配制成溶液，分别精密量取一定量，注入仪器，记录色谱图。

While the dry and wet crock fastnesses reached to 4 and 4～5 respectively if 16% of the low-formaldehyde binder was employed. And the formaldehyde content was in the limit of eco-lables.

胶乳应用作涂料印花粘合剂，当无甲醛粘合剂使用量为20%（涂料用量5%）时，印花织物于100℃烘干3min，印花品的牢度、手感、鲜艳度、给色量等多个方面的结果都符合国家标准；低甲醛产品使用量为16%（涂料用量5%），在150℃焙烘3min后，印花品的干湿摩擦牢度分别可达到4和4-5级，手感柔软。
