1.A first-order phase transition is found in the tethered surface model, which is defined by the Gaussian bond potential and the bending energy. The smooth phase of the model is separated from the crumpled phase by the transition on triangulated spherical surfaces. The first-order transition is independent of how the bending energy is discretized, and it is also independent of how the surface is triangulated.2.The above-mentioned first-order transition is independent of whether the bending energy is the extrinsic one or the intrinsic one.3.The above-mentioned first-order transition is independent of whether the surface is sphere or torus.4.The first-order transition of a tethered surface model changes to a second-order one when the surface is expanded with two point boundaries of fixed distance. The model is the one that is defined by the Gaussian bond potential and the intrinsic bending energy.

1.在束缚的表面模型中发现了一阶相变，该模型由高斯键势和弯曲能来定义。模型的平滑相通过三角形球形表面的过渡将模型的平滑相与皱巴布相分开。一阶过渡与弯曲能离散的方式独立于独立于三角形的表面方式。2。上述一阶过渡与弯曲能是外在的一个还是内在的。3。上述一级过渡是否独立于表面或torus sprorditions pression。以固定距离的两个点边界扩展。该模型是由高斯键势和固有弯曲能来定义的模型。
