The peculiarities in the dynamics of the director reorientation in confined nematic liquid crystals (LCs) under the influence of a strong electric field E$\mathbf{E}$ directed at an angle α$\alpha$ to the magnetic field B$\mathbf{B}$ have been investigated theoretically on the basis of the hydrodynamic theory including the director motion with appropriate boundary and initial conditions. Analysis of the numerical results for the turn-on process, when the strong electric field E$\mathbf{E}$ is suddenly applied, provides an evidence for the appearance of the spatially periodic patterns in confined LC film. Calculations show that when the angle α$\alpha$ tends to be 90°$90°$, the optimum wavelength, giving the fastest response, provides the lower effective viscosity γ_eff(α)${\gamma }_{\mathrm{eff}}\left(\alpha \right)$, which is less than one in the bulk nematic phase. So, a lower value of γ_eff(α)${\gamma }_{\mathrm{eff}}\left(\alpha \right)$ gives a faster relaxation times, as observed experimentally by using the time-resolved deuterium NMR spectroscopy.

在强电场E的作用下，密相向列液晶（LCs）中指向矢重取向动力学的特殊性$\mathbf{E}$定向成角度α$\alpha$对磁场B$\mathbf{乙}$在水动力理论的基础上进行了理论研究，包括具有适当边界和初始条件的指向矢运动。对于强电场E时开启过程的数值结果进行分析$\mathbf{E}$突然施加了α射线，这为局限LC膜中空间周期性图案的出现提供了证据。计算表明，当夹角α$\alpha$往往是90°$90°$时，最佳波长，给予最快的响应，提供了较低的有效粘度γ _EFF（α）${\gamma }_{\mathrm{效}}\left(\alpha \right)$，在批量向列相中小于一。所以，较低的值γ _EFF（α）${\gamma }_{\mathrm{效}}\left(\alpha \right)$ 通过使用时间分辨氘NMR光谱在实验中观察到，它给出了更快的弛豫时间。
