通过对过冷甘油的非线性磁化率的研究，我们发现施加静电场使玻璃化转变温度{T}{g}$在{E}{st}$中增加了一个二次量。这有重要的结果：(I)它加强了过去几年提出的两条路径之间的关系，揭示了接近{T}_{g}$的动力学关联体；(Ii)它澄清了对非线性测量的解释；(Iii)它产生了一个新的玻璃化转变的控制参数，这为实验加深我们对玻璃的理解铺平了道路。
By studying a nonlinear susceptibility on supercooled glycerol, we show that applying a static field ${E}_{st}$ increases the glass transition temperature ${T}_{g}$ by an amount quadratic in ${E}_{st}$. This has important consequences: (i) it reinforces the relation between the two paths put forward in the last years to unveil the dynamical correlation volume close to ${T}_{g}$; (ii) it clarifies the interpretation of nonlinear measurements; (iii) it yields a new control parameter of the glass transition, which paves the way for experiments deepening our understanding of glasses.
