The synergistic effects and flame-retardant properties of melamine cyanurate with magnesium hydroxide in halogen-free flame-retardant ethylene vinyl acetate copolymer blends have been studied using the cone calorimeter test, thermogravimetric analysis, laser Raman spectroscopy, limiting oxygen index, UL-94 test, and measurements of rheological properties.

通过锥形量热器试验、热重分析、拉曼光谱分析、氧指数、垂直燃烧试验及流变性能测试，研究了氰尿酸三聚氰胺和氢氧化镁在无卤阻燃乙烯-醋酸乙烯共聚混合物中的协效阻燃作用。

Glucose, glycerol, sucrose, mannitol have good protection from the heat denaturalization of deer placenta polypeptide and the impact of glucose is the best, the 20 % concentration of the protector is appropriate.

葡萄糖、丙三醇、蔗糖、甘露醇对鹿胎盘多肽的热变性有明显的保护作用，其中以葡萄糖的保护效果最好，保护剂的浓度为20%时较为适宜。

Urea is a common chemical denaturant of proteins.

尿素是常用的蛋白质变性剂，在胶粘剂研究中起着重要的作用。

In Chapter 2 of this thesis, the kinetic equation of substrate reaction in presence of denaturant has been derived. A re-examination of the effect of high concentrations of guanidine hydrochloride on the inactivation of papain, taking into consideration the effect of high concentrations of guanidine hydrochloride on the Michaelis constant, showed that, for papain, the substrate gives no protection on its inactivation.

我们在第二章中推导了变性剂存在下的底物反应动力学方程，并在考虑了高浓度盐酸胍对酶催化反应米氏常数的影响的前提下，根据推导的动力学方程重新分析了盐酸胍存在下木瓜蛋白酶的失活动力学，结果表明底物对木瓜蛋白酶的失活没有保护作用。

In Chapter 6, an extensive kinetic study of the inhibition of ribonuclease A and papain by urea has been performed. The results suggest that the effect of urea on activities of these enzymes can be well described by the denaturant binding model. The binding constants of urea determined by the present method are nearly identical to that determined from a variety of different studies on model compounds and proteins.

我们在第六章中研究了脲作用下核糖核酸酶A和木瓜蛋白酶的抑制动力学，发现变性剂结合模型可以很好地描述脲对这两个酶活力的影响，而且用我们自己建立的方法测得的脲与蛋白质的结合常数与前人通过对模型化合物和某些蛋白质的研究所获得的数值基本一致。

The kinetic theory of the substrate reaction during modification of enzyme activity has been applied to study the inactivation kinetics of enzymes by denaturant. However, an important problem related to the determination of the inactivation rate constants has not been considered in a previous publication.

虽然酶活力不可逆抑制的动力学理论已经被推广应用于变性剂作用下的酶失活动力学研究，但以往的研究忽略了一个与测定失活速度常数相关的重要问题。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
