Thermal stability of well-crystallized cubic boron nitride (cBN) films grown by chemical vapor deposition has been investigated by cathodoluminescence (CL), Raman spectroscopy, and scanning electron microscopy (SEM) with the cBN films annealed at various temperatures up to 1,300 degrees C. The crystallinity of the cBN films further improves, as indicated by a reduction of the relevant Raman line width, when the annealing temperature exceeds 1,100 degrees C. Structural damage or amorphization was observed on the grain boundaries of the cBN crystals when annealing temperature reaches 1,300 degrees C. The CL spectra are found to be unchanged up to 1,100 degrees C after annealing at 500 degrees C, showing the stability of the cBN films in electronic properties up to this temperature. New features were observed in the CL spectra when annealing temperature reaches 1,200-1,300 degrees C. 相似文献

In this paper, a cost-based job shop problem (JIT-JSP) is proposed to model the multi-order processing procedure in a just-in-time (JIT) environment. The objective of JIT-JSP is to minimize three costs: work-in-process holding cost of half-finished orders, inventory holding cost of finished orders and backorder cost of unfulfilled orders. A modified tabu search (MTS) method is developed to improve the schedule quality by searching the neighbourhood of a feasible schedule iteratively. The MTS method is comprised of three components that help to ensure a more effective searching procedure: neighbourhood structure, memory structure and filter structure. Computational results show that the MTS method significantly improves the initial schedule generated by an arbitrarily selected dispatching rule. 相似文献

Raman spectroscopy has demonstrated great potential in clinical and biomedical applications. However, slow data acquisition due to weak Raman signals has prevented its wide use, especially in an imaging setup. In this paper, we propose a novel solution in which the full Raman spectrum can be rapidly reconstructed from a few narrow‐band measurements based on Wiener estimation. This method, using both traditional Wiener estimation and modified Wiener estimation, has been evaluated on Raman spectra collected from live, apoptotic and necrotic leukemia cells with several different types of band‐pass filter choices. Two rules of thumb were identified to guide the choice of filters. Our results indicate that the agreement between reconstructed and measured Raman spectra was excellent according to either the mean root mean square error or the classification accuracy. Therefore, Raman reconstruction from narrow‐band measurements represents a new direction in fast Raman imaging for the investigation of fast changing phenomena.
