For optimizing the measurement of coal particle flow, the characteristics of laser-induced plasma, including optical breakdown, the relative standard deviation of repeated measurement, partial breakdown spectra ratio and line intensity, were carefully analyzed.
Nanosized ZnO was prepared through hydrothermal process and characterized by scanning electron microscopy, X-ray diffraction and laser-induced breakdown spectra measurement techniques.
For further characterization of ZnO, a Spectra-Physics laser source (model LAB-170, pulsed Nd YAG, Spectra-Physics Inc., Santa Clara, CA, USA) was used to get laser-induced breakdown (LIB) spectra of the samples.
Breakdown of spectra used for E-value calibration.
The impingement of a streamwise vortex on a fin is investigated experimentally with high-image-density particle image velocimetry (PIV) and dynamic pressure transducers in order to relate the structure of vortex breakdown to the spectra of surface pressure along the fin.
29 At the other end of the age spectrum, the breakdown of dermal tissue, flattening of the dermal-epidermal junction, epidermal thinning, and xerosis contribute to an increased risk of skin tears and to itchy conditions in elderly individuals.
"21st Century Breakdown" lodges a full-spectrum protest, even calling for revolution, at a time of relative national unity.
Recent research highlights the risks of communication breakdowns along the entire spectrum of test-result abnormality, including significantly abnormal but nonemergent findings.
The total number of spectra produced after extraction from the NHLBI set was 26159 and a detailed breakdown of the numbers of spectra by instrument type is given in Table 2.
