Study on Negative Pressure Approach for Surface Profile Measurement With Coolant Condition
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.In this work, we proposed a negative pressure approach, which could help a 2D laser sensor conduct in‐process measurement with coolant condition. The applicator to conduct a negative pressure approach was studied and designed. The experimental results show that the negative pressure approach could help 2D laser beam conduct measurement on a workpiece ...

Gaoya dianqi, 2017 对于高压断路器灭弧室动态流场的数值计算,往往采用动网格技术进行模拟,目前众多涉及动网格的流场模拟计算都采用Ansys Fluent来完成的。相比之下,Ansys CFX具有较广泛的应用范围和诸多优点,能够解决前者的诸多不足,但其缺点是不能直接解决涉及较大变形的动网格计算。文中针对此不足,基于UX和Ansys CFX两款商业软件,通过对它们进行二次开发,得到了一种适用于动态流场计算程序;通过对某高压断路器灭弧室实际流场进行动态计算,验证了该方法的可行性和准确性。该方法在一定程度上解决了Ansys ...

A Novel Conjugated Octupole–Quadrupole Ion Guide Achieving High Transmission
Rapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.ABSTRACT Rationale Ion transmission efficiency from the atmospheric pressure ion source to the vacuum is critical for the sensitivity of mass spectrometers. In this study, we developed a novel conjugated octupole–quadrupole ion guide—the 8–4 pole ion guide—that achieves high transmission efficiency.
