尿酸分解的

The flame retarding mechanism of MCA on POM was that formaldehyde and formate acid were absorbed by melamine resulting from melamine cyanurate pyrolysis and temperature of burning materials was reduced because melamine cyanurate sublimation absorbed heat and thermalplastic polyurethane absorbed formaldehyde and enhanced stability of POM composites.

热失重、红外和气质联用分析表明，MCA／TPU复合阻燃剂对聚甲醛的阻燃作用是由于三聚氰胺氰尿酸盐高温分解并吸热，降低材料燃烧区域的温度；另一方面MCA高温分解生成的三聚氰胺可吸收聚甲醛分解产生的甲醛和甲酸；此外，TPU可提高聚阻燃甲醛的热稳定性，有利于阻燃。

Objective To study the effects of heroin on adenosine deaminase in small inteseine and plasma uric acid content in rats.

目的：通过检测大鼠小肠腺苷脱氨酶和血浆尿酸的含量探讨海洛因对大鼠小肠腺苷酸分解代谢的影响。

Uric acid in the human body has two main sources: from a small number of protein-rich foods from decomposition; most of the body from amino acids,-ribose, and other small molecules, nucleic acid synthesis and catabolism generated.

人体内的尿酸主要有两个来源：小部分从富含核蛋白的食物中分解而来；大部分则由体内氨基酸、磷酸核糖、其它小分子化合物合成及核酸分解代谢中产生。

Most mammals have a gene that makes an enzyme called uricase that breaks down uric acid, but humans lack the ability.

大多数哺乳动物都有一个叫做尿酸酶的基因来分解尿酸，但人类缺乏这种能力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
