摘要翻译：
本文利用分子动力学计算机模拟研究了在形成Ni{0.8}Zr{0.2}-体系中，密质液体的模式耦合理论(MCT)提出的动态玻璃化转变临界温度T_c。对临界温度T_c从不同的量进行了分析，并检验了估计值的一致性，即(i)非遍历性参数作为MCT方程在阻滞态的渐近解，(ii)描述熔体在遍历侧向阻滞态逼近的${bf{g}}_m$参数，(iii)熔体中的扩散系数。结果T_c值的一致性在10%以内。

英文摘要：
We use molecular dynamics computer simulations to investigate a critical temperature T_c for a dynamical glass transition as proposed by the mode-coupling theory (MCT) of dense liquids in a glass forming Ni_{0.8}Zr_{0.2}-system. The critical temperature T_c are analyzed from different quantities and checked the consistency of the estimated values, i.e. from (i) the non-vanishing nonergodicity parameters as asymptotic solutions of the MCT equations in the arrested state, (ii) the ${\bf{g}}_m$-parameters describing the approach of the melt towards the arrested state on the ergodic side, (iii) the diffusion coefficients in the melt. The resulting T_c values are found to agree within about 10%.
