In the next set of steps, we define the triggers for the transitions between the states. First, we set up the transition that occurs when we are told the order has been shipped.

在下面的步骤中，我们将定义状态间转换的触发器。

For smaller clusters, there is no clear characteristic of first-order phase transition during the melting, implying a coexistence of solid and liquid phases due to finite-size effect.

对于较小的团簇，融化曲线没有出现清楚的一级相变特征，意味着由于尺寸效应导致的固态液态共存。

Near the transition temperature, a thermal hysteresis was found in dielectric, pyroelectric and piezoelectric measurements. Thus the transition should be of the first order transition.

在相变温度区域里，介电、热电和压电都有明显的热滞效应，具有一级相变特性。
