    去噪算法在现代图像处理应用中占有极其重要的地位。然而图像去噪的过程总是伴随着图像的模糊。本文提出了一种对彩色图像细节保持较好的局部自适应的去噪算法--基于个数判断噪声的前提下结合线性插值、非线性插值(这里主要指中值滤波)滤波对噪声图像进行处理,得到较理想的效果。和领域平均法、倒数梯度加权法、纯线性插值法、纯中值滤波法等相比较,其效果改善明显。Denoising is very important in image processing. Unfortunately denoising will blur the original image, founding a way to keep the details of a noisy image is necessary. We shown a new adaptive algorithm of denoising which has a better performance on keeping image's details-counting the difference of a window combining with the linear interpolation or nonlinear sort filter. We get a better result comparing with mean filter 、 reciprocal gradient filter、linear filter and median filter

    利用激光气化铁氰化钾或亚铁氰化钾并利用飞行时间质谱检测方法对氰化钾团簇的形成机理进行了研究,结果发现:团簇正离子可归属为(K(KCN)n^+,n=0~37,它们的幻数为n=4,13,22,37;团族负离子可归属为(KCN)nCN)^-,n=0~13,它们的幻数为n=4,13。这些幻数与氯化钠等碱金属卤化物团簇体系完全一致。这表明:它们的团簇结构应该是相同的,即1×3×3(n=4)3×3×3(n=
