采用蒙特卡罗数值模拟方法详细研究了无限薄硬片晶弯曲成浅透镜状粒子时各向同性-非均匀相变的特征变化。首先，在以前的参考模型系统中的这种相变被重新检查并更准确地定位。然后，它是定量示出的，这已经相当弱，但明显的一阶相变进一步减弱后，弯曲的血小板到这样的程度，由于这些颗粒的薄，不赞成其预排空的过渡到（部分）位置有序的相，各向同性的临界点的限制可以任意接近。
Monte Carlo numerical simulations are used to study in detail how the characteristics of the isotropic-nematic phase transition change as infinitely thin hard platelets are bent into shallow lens-like particles. First, this phase transition in the former reference model system is re-examined and more accurately located. Then, it is shown quantitatively that this already quite weak but distinctly first-order phase transition weakens further upon curving the platelets to such an extent that, thanks to the thinness of these particles that does not favor its pre-emptying by a transition to a (partially) positionally ordered phase, an isotropic-nematic tricritical point limit can be arbitrarily closely approached.
