A support system is the main load-bearing component of sample table for neutron stress spectrometer, and air bearing is an important element of a support system. The neutron stress spectrometer sample table was introduced, and the scheme for air bearing combination was selected. To study the performance of air bearing center cross gap, finite element models (FEMs) were established based on air motion and Reynolds equations, effects of air supply pressure, and gap parameters on the overturning moment and bearing capacity of air bearing center cross gap were analyzed. Results indicate that the width, depth, and height differences of the marble floor gap played important roles in the performance of the air bearing. When gap width is lesser than 1 mm and gap depth is lower than 0.4 mm, bearing capacity and overturning moment would vary rapidly with the variation of the width and depth. A gap height difference results in the bearing capacity dropping rapidly. The FEM results agree well with experimental results. Further, findings of the study could guide the design of the support system and marble floor.

测量柔性有机显示器件对水蒸气的高阻隔性,是确保其可靠性所面临的重大工程挑战。一方面,目前缺少10-6 g·m-2·d-1量级的水渗透率测试手段;另一方面,目前也没有标准的超阻隔样品用于渗透率测量的校准。为了对渗透过超阻隔材料的痕量水蒸气流量进行高灵敏、短周期测量,本文将渗透模型集成至基于渗透分子动态积累、检测和抽空的高灵敏质谱测量中,从而开发出了一种具有预测功能的测量仪器。通过使用标准聚合物样品进行校准,确保了测量结果的可靠性。校准后的水蒸气渗透检测下限在10-7g·m-2·d-1量级,满足超阻隔渗透的测量灵敏度要求。本文利用渗透实验数据对所开发的预测渗透模型进行了测试评估,使得利用非稳态数据预测稳态渗透率成为可能,实现在更短的时间内有效开展超阻隔测量。
