酸性橙

Another example is methyl orange, which is red in acids and yellow in alkali solutions.

另一个例子是甲基橙，它在酸性溶液中为红色而在碱性溶液中为黄色。

Results Using different concentrations of 5fluorouracil to deal with A549 cells, with the increase in drug concentration and treatment time,cell survival rate decreased significantly;and low concentration of 5fluorouracil induced the cell spread and increased vacuolization within the cytoplasm, acridine orange staining showed an increase in acidic vesicles,high concentration made the cell round and cell apoptosis.

结果不同浓度的5氟尿嘧啶处理A549细胞，随着药物浓度的增加和处理时间的延长，细胞存活率明显下降；且低浓度使细胞呈铺展状态，细胞质内空泡增多，吖啶橙染色显示酸性膜泡增多，高浓度使细胞变圆，出现凋亡状态。

In the acid medium,residual chlorine discolors the methyl orange whose biggest wave length of absorption is 510 nm.

在酸性介质中，余氯使甲基橙褪色，最大吸收波长510 nm，摩尔吸光系数A510=5.41×10-3l/mol.cm，余氯质量浓度在(0.05~1.00)mg/l范围内遵守朗伯？？

The paper still studied the soluble characteristic of soybean peptides in the acid beverage, and reviewed the color, flavor and stability of the beverage such as apple, haw and orange juice after adding soybean into them and the optimum proportion.

论文研究了大豆多肽在酸性饮料中等电点可溶的特性，研究开发了大豆多肽苹果汁、山楂汁、橙汁等饮料，考察了大豆多肽果汁饮料的色泽、风味、稳定性等指标，并确定出最佳配比方案。

Methods:Vanadium was determined by dual-wavelength catalytic spectrophotometric method which was based on the vanadium catalyzing oxidation of acridine orange and acid chrome blue K by potassium bromate in 0.010 mol/L H2SO4 medium.

在硫酸介质中，利用钒催化溴酸钾氧化吖啶橙和酸性铬蓝K褪色反应，分别在476 nm和556 nm处测量催化体系和非催化体系的吸光度的变化，用双波长催化光度法测定痕量钒。

The dyes were extracted from textiles composed of natural or chemical fibers by methanol under ultrasounication, and then eluted with gradient by acetonitrile and 5 mmol/L ammonium acetate from an RP-C18 column with two segments in effluents. The first effluents accommodated Acid Red 26, Direct Blue 6, Direct Black 38 and Direct Red 28 with negative ionization mode, while the second accommodated Basic Red 9, Basic Violet 14, Disperse Blue 1, Disperse Orange 11 and Disperse Yellow 3 with positive ionization mode. Thus the investigated compounds could be identified simultaneously with single-run analysis no matter which type of the fibre the sample was and no matter which category of the dye the analyte was.

用甲醇超声同时提取天然纤维和化学纤维上的染料，以5 mmol/L乙酸铵和乙腈为流动相在C18柱上于前段洗脱酸性红26、直接蓝6、直接黑38和直接红28（采用电喷雾质谱负离子模式检测），于后段洗脱碱性红9、碱性紫14、分散蓝1、分散橙11和分散黄3（采用电喷雾质谱正离子模式检测），实现了对不同种类纤维织品中分属4类性质不同染料的一次提取和一次分析检测。

Methyl orange is one of acid dyes, but its range of use is greatly limited because of its low light and thermal stability.

甲基橙是一种酸性染料，但因为它的光和热稳定性较差，使其应用范围和使用效果受到了一定限制。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
