Their biological properties show that the proposed composite coatings exhibit well-balanced biocompatibility and antibacterial activity, promoting osteoblasts viability and ... Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at … WebJul 18, 2016 · 图4 irm距离查询相似度排序结果. 图5 平均高频信号强度查询相似度排序结果. 在本文中irm距离查询是基于图像区域的颜色直方图,所以检索出来的图像和查询图像在光谱特征上比较相似。 port washington ny adoption center
