efficiently collecting their photon emission, and generating signals that enable them to be observed in the presence of a variety of noise sources. Total internal reflection fluorescence (TIRF) microscopy, for example, can achieve single fluorophore resolution ...
Considering the results of the statistical study, we propose some practical recommendations for selecting a threshold to classify AE event types in experimental studies. 展开 关键词: acoustic emission focal mechanism statistical testing laboratory experiments rock physics ...
As a "testing ground" for national progressive reform, the NHTDZs are driven by the national mission23,48. This process realizes the efficient recycling of resources with the specialized agglomeration of HNTEs. It adheres to circular economy and intensive development as a means of promoting coordi...
An aerodynamic particle sizer (0.54–20 μm diameter) samples exhalate from within a cardiopulmonary exercise testing mask, at rest, while speaking and during cycle ergometer-based exercise. Exercise challenge testing is performed to replicate typical gym-based exercise and very vigorous exercise,...
6.Application of Electromagnetic Acoustic Emission Technology in Non-Destructive Testing电磁声发射技术在无损检测中的应用 7.The development of digital and waveform acoustic emission (AE) technology made the recognition of AE source possible.波形数字声发射技术的发展给声发射源的特性识别带来了可能。
Additionally, the AE technique possesses the advantage of monitoring the damage in real-time, which make AE a beneficial tool to locate and identify fatigue crack growth throughout the testing. Note that the fatigue crack in quasi-brittle materials, such as concrete, is difficult to be observed...
