It was found that ARA was composed of esterification products of (2-HEA)-ester with pimaric acid, dehydroabietic acid, abietic acid and two isomers of acrylpimaric acid. ARA is a good crosslinking agent which can copolymerize with most vinyl monomers. The properties of solvent-resistance and heat resistance of the copolymer were improved considerably by the use of ARA.

实验结果表明：ARA主要由海松酸、脱氢枞酸、枞酸和丙烯海松酸的二种异构体的丙烯酸－2-羟基乙基酯的酯化产物组成，ARA是一种良好的交联剂，可与大多数乙烯基单体共聚合，其与MMA的共聚物的耐溶剂性和耐热性均得到了较大幅度的提高。

Cyclic AMP (cAMP; adenosine-3',5'-monophosphate) A form of adenosine monophosphate formed from ATP in a reaction catalyzed by the enzyme adenyl cyclase.

环腺苷酸：腺苷酸的一种类型。是由 ATP 在腺苷酸环化酶的催化下生成的结构。

In this process, the electrolylic bath with cationic exchange membrance and leas electrode is used. The cathode liquor is oxalic acid, the anode liquor is diluted sulfuric acid. The process above has following advantages with high yield, top quality, lower cost, no "three wastes" pollution, and no oxalic aldehyde in the product. It is a cleaner and environment-friend technology, and is a development trend for production of glyoxalic acid. Complete analytical process for raw materials, intermediate and final products were established.

本论文通过对乙醛酸合成路线的研究，确定了草酸电解法制乙醛酸的工艺路线，此法采用装有阳离子交换隔膜和铅电极的电解槽，阴极电解液为草酸溶液，阳极电解液为稀硫酸，该工艺具有产品收率高、质量好、成本低、无三废污染、产品中无乙二醛等特点，是一条清洁、绿色工艺，是生产乙醛酸的主要发展方向。

WO3, an interlayer compound prepared by J. W. Johnson (1981) using yellow tungstic oxide hydrate. Suspension of white powdery tungstic acid in anhydrous pyridine yields on standing for 2 wk whiteHW4O13.3H2O. IR and DTA studies revealed the connection between that pyridine polytungstate and white powdery tungstic acid (microcryst.), whose composition may thereby be assigned as H2W4O13.nH2O.

WO3。粉状白钨酸在无水吡啶中放置两周后可得到另一种化学式为(C5H5NH)HW4O13.3H2O的吡啶化合物，经IR和DTA研究可初步说明该化合物与粉状白钨酸之间的联系，并因此推测白钨酸的组成可能为H2W4O13.nH2O。

A salt of tungstic acid .

黄原酸盐一种黄原酸的盐，尤指单一的黄原酸盐。
