天冬氨酸的

Aspartic acid is one of the twenty kinds of basic aminos which make up the protein, it has been used in biochemical reagents and clinical medicine .

天冬氨酸是构成蛋白质的20种基本氨基酸之一，它在生化试剂和临床医学方面具有广泛的应用。

The results showed that pH and the dosage of aspartic acid or citric acid had a significant effect on the extraction efficiency.

以天冬氨酸作为萃取剂，研究了其对上海桃浦污水处理厂污泥中重金属的萃取性能，重点考察了萃取体系pH值对重金属萃取的影响，并在相同条件下与柠檬酸的萃取过程进行比较。

Pepstatin,which contains the novel amino acid statine,is a natural pentapeptide isolated from natrue product.It is a good inhibitor of most aspartyl proteases with a K_i in the nanomolar range.

从天然产物中分离得到的Pepstine对大多数天冬氨酸蛋白酶的抑制率达纳摩尔级，但其选择性差、溶解性弱。

The low phosphate scale and corrosion inhibitor consists of hydroxyl ethylidene bisphosphoric acid in 0.5-1 mg/l, hydrolyzed polymaleic anhydride in 0.5-2 mg/l and polyasparic acid in 1-2 mg/l, with the total concentration being 3 mg/l.

还含有0.5～2mg/L的水解聚马来酸酐和1～2mg/L的聚天冬氨酸，低磷阻垢缓蚀剂的总质量分数之和为3mg/L。

Gathers the aspartic acid isone kind has good anti- is filthy, the slow eclipse performanceenvironment friendly water treatment medicinal preparation, may use inthe recirculated cooling water, the boiler and the oil gas watertreatment, may prevent filthily stops up the pipeline and the stratum,enhances the thermal efficiency, prevents the metal the corrosion.

聚天冬氨酸是一种具有良好阻垢、缓蚀性能的环境友好水处理剂，可用于循环冷却水、锅炉及油气水处理，可防止垢堵塞管道和地层，提高热效率，阻止金属的腐蚀。

Polyaspartic acid is easily ring-opened to form polyaspartic acid derivatives with a side chain founctional group.The second component can be added into aspartic acid by copolymerization to improve polarity and crystallization of primary polymer,and can make primary polymer without reactive group functionalize.

聚天冬氨酸是近几年来在全球销量日增的绿色化学品，由于它具有类似蛋白质的酰胺键结构，是一种生物可降解材料[1-2]，最终可降解成水和二氧化碳，具有良好的生物相容性，对环境友好。

When the coverage is increased,the aspartic acid molecules can finally form an overlayer with uniform contrast but could never form any ordered structures.

随着覆盖度的提高，天冬氨酸分子最终在Cu(0 0 1)表面形成一均匀衬度的吸附层，但并不形成有序吸附结构，也不能使台阶发生小面化。

The polymer structure is characterized with IR, NMR and is proved to be PASP. The suitable reaction temperature and time are 220℃～240℃ and 3-4 h at no catalyst in the fields of scale inhibition and fertilizer synergia.

反应机理和实验数据表明，在本文研究范围内，无催化的缩聚反应属于三级反应，生成聚合物聚合度的平方与天冬氨酸初始浓度的平方和反应时间成正比。

Aspartic acid An AMINO ACID formed by transamination, in which the amino group of dlutamic acid is transferred to oxaloacetic acid.

天冬氨酸：由转氨基作用形成的一种氨基酸，谷氨酸的氨基基团被转移到草酰乙酸中。

BACKGROUND: Aromatic anesthetics exhibit a wide range of N -methyl-d-aspartate receptor inhibitory potencies and immobilizing activities.

背景：芳香族麻醉剂显示出广泛的抑制 N -甲基-d-天冬氨酸受体的作用和制动作用。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
