The surface of nano-silicon dioxide (nano-SiO2) particles was modified by small molecular coupling agent KH-560 and macromolecular SEA-171, respectively, to change the activity structure. nano-SiO2 then used for reinforcing cyanate ester resin (CE). Influences content interfacial structure over thermal frictional properties nano-SiO2/CE composites were investigated. mechanism modification silicon SEA-171 discussed. experimental results show that addition agents increased bonding between CE...
Recent advancements in data-driven deep learning methods have significantly improved rolling bearing fault diagnosis. However, these frameworks face limitations due to data defects and inadequate feature extraction. To overcome obstacles, this paper proposes a novel extraction causal model-based diagnosis framework. This framework leverages discovery derive models from real data, accurately estimate effects, enhance performance. Specifically, the proposed utilizes Time-reassigned...
To suppress spatial hole burning, a direction related polarizer is adopted in Er-doped fiber ring laser gyroscope. decrease the frequency drift caused by fluctuation of environment temperature, polarization maintaining (PM) substituted for single mode cavity. obtain better reciprocity, two 90-deg rotations PM are introduced. Through manners, stable single-mode continuous wave lasers observed simultaneously both output directions. At last, performance gyroscope based on achieved.
Bridgman anvil is a useful and effective tool in high-pressure research. However, this apparatus, the pressure distribution essentially centrosymmetric. Thus, considerable gradients exist gasket sample chamber respectively, uniform area limited. To improve uniformity flat face supported anvils, we design strip instead of conventional round adopt an assortive gasket. Principle analysis series calibration experiments are also presented paper.The construction relevant parts apparatus shown...
In this paper, an improved split-ring resonator (ISRR) cell is proposed to realize wide stopband and miniaturization. This comprises a transverse microstrip branch in middle two gaps on both sides with tapped-line input output. The transmission coefficient derived for ISRR based the distributed circuit theory odd-even mode theory. Then novel low-pass filter (LPF) designed by cascading several cells terahertz millimeter. LPF possesses great characteristics such as stopband, deep zeros small...
A compact fiber tip refractive index sensor using FIB-milled gold-coated singlemode-multimode-singlemode structure is demonstrated. Focused ion beam (FIB) exploited to cut the obtain a flat end-face and then layer of gold coated on surface, increase its reflection. An average sensitivity 265 nm/RIU obtained experimentally with ~2.94 μm diameter (SMST). Because several advantages, including compactness, ease fabrication, linear response, high sensitivity, easy connection other fiberized...
For the ceramic matrix composites, manufacturing defects are key issues that make their elastic constants difficult to predict. A method is proposed predict equivalent of needled C/SiC composite. This consisted multiscale model construction and cross-scale analysis. In construction, two types defects, pore fiber deflection, were analyzed characterized in scale models. analysis, theoretical prediction was used link microscopic mesoscopic scales. The periodic boundary condition macroscopic...
Abstract When the positive pressure explosion-proof robot is in ventilation, if air filled into cavity with a constant pressure, stable flow field will be formed cavity. There stagnation zone of airflow corner position, which cause accumulation explosive gas. In order to solve this problem, ventilation method periodic pulse intake adopted on basis existing structure. The variation gases concentration time under and different periods amplitudes compared. According simulation experimental...
