From the numerical results of critical conicity calculatians for bogies with different steering stiffness and different construction parameters, the paper concludes that the low conicity instability can be reduced by means of optimizing the bogie parameters to a va...

得到不同导向刚度下产生失稳的临界踏面锥度和不同锥度下的临界速度值。研究发现，通过参数的合理匹配，可使临界锥度降至常见最小锥度以下，从而可以避免低锥度失稳，为迫导向转向架的参数设计提出了一个新的准则。

The wall has no support during the construction stage and the calculationbased on the national standard GB 50018-2002 (Technical code of cold-formedthin-wall steel, structures) should be reliable and safe. The crankle destabilizationof the studs with cold-formed channel section should be taken into account whencalculating the load-carrying capacity. The warpings at both ends of the sectionshould be calculated without any constraint when converting the crankledestabilization into the slenderness rationλ_w.

墙体在施工阶段基本为无墙体支撑，此时，按现行国标《冷弯薄壁型钢结构技术规程》(GB 50018-2002)规定计算是可靠、偏安全的，在计算其承载能力时应考虑单轴对称冷弯卷边槽钢截面立柱弯扭失稳，在计算立柱弯扭失稳换算长细比λ_w时，截面两端翘曲宜按不受到约束条件计算。

Vitamin C and Cysteine had great inhabitation effect on POD activity, the inhibition rate reached 94% and 92% respectively.

在温度为60℃以上时过氧化物酶的失活率升高，在温度为70℃以上时过氧化物酶基本失活。

In this region, though the particle has been over the springpoint, the particle can still be kept in a steady damped oscillation but not flying lost predicted by the Davis theory.

首次从理论上证实了颗粒在电动悬浮天平中的状态除了静止悬浮和振荡飞失之外，还存在一个过渡区，此时颗粒虽然越过了Davis理论定义的弹跳点，但仍能保持稳定的阻尼振荡，而非Davis理论所预测的飞失状态。

It was showed that ultrasonic did not change the reaction mechanism. The deactivation of cellulase was studied briefly.

说明氧促进了纤维素酶的失活，采用氮气保护进行水解是减小纤维素酶失活的一种有效措施。

"Where a relevant office-holder takes any action in relation to property of a defaulter which is liable to be dealt with in accordance with the default rules of a recognized clearing house,"

凡失责人的财产可按照认可结算所的失责处理规则处理，而有关人员就该财产采取任何行动

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。

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。

Objective: To compare the clinical effect of dental pulp devitalization with polyoxymethyleni and modified method respectively in two groups of patients with different age.

目的：比较改进多聚甲醛牙髓失活法与传统失活法的临床效果，并观察其在60岁以上老年人的效果差异。

During melting and throughout the crystal growing process the barium acts as a devitrification promoter and creates a layer of devitrified silica on the inside crucible surface in contact with the melt resulting in a lower level of contaminants in the melt and grown crystal.

在熔化以及晶体生长的整个过程中，钡起失透促进剂的作用并且在与熔体接触的坩埚内表面上产生失透二氧化硅层，从而降低了在熔体以及生长的晶体中的污染物量。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
