将气-水界面上倾斜相（L2和L '2）的两亲性单分子膜在压缩-剪切诱导下的倾斜方位取向分析为压缩诱导剪切流作用下分子正交六角结构弹性畸变的动力学平衡。从理论上表明，压缩可以诱导分子倾斜躺在沿着和/或对流动方向。所有这些倾斜构成了分子尾部沿沿着方向的初始随机倾斜方位角。在临界压缩速度下，它在空气-水界面处引起C（无穷大）->C（2 v）对称性转变。利用麦克斯韦位移电流和光学二次谐波测量，在4-庚氧基-4（'）-氰基联苯单分子膜中对上述理论结果进行了实验验证。
Compression-shear-induced tilt azimuthal orientation of amphiphilic monolayer in tilting phases (L2 and L'2) at the air-water interface is analyzed as dynamical equilibrium of the elastic distortion of orthogonally hexagonal structure of the molecules under compression-induced shear flow. It is shown theoretically that the compression can induce molecular tilts lying along and/or against the flow direction. All these tilts makeup the initial random tilt azimuth of the molecular tails along a uniform direction. At a threshold compression speed, it causes a C(infinity)-->C(2v)-symmetry transition at the air-water interface. With Maxwell displacement current and optical second-harmonic generation measurements, the above theoretical results are verified experimentally in a monolayer of 4-heptyloxy-4(')-cyanobiphenyl.
