目的:通过引入坡变换,揭示表面测量中形态学操作的本质。创新点:引入坡变换,将空间域的形态学膨胀操作转换为坡域的加法操作,揭示结构元素对表面轮廓坡度和曲率的改变。方法:1.基于坡变换理论,空间域的切膨胀操作对应于坡域的加法操作(图9);2.分析圆结构元素作用于正弦波和圆的理论解;3.用不同半径的圆结构元素作用于正弦波,分析切膨胀和经典膨胀的相同和不同之处。结论:1.坡变换将形态学操作从空间域转换到坡域,可获取类似于傅立叶变换将卷积操作从空间域转换到频域的分析能力;2.切膨胀操作为经典膨胀操作的上确界,但会产生重叠区域。

研究旨在比较用两种脂质乳剂进行全静脉营养(TPN)后脑脂质成分的变化,所用的脂质乳剂一种是长链脂肪酸(LCT),另一种是由长链和中链脂肪酸组成(MCT/LCT50%/50%)。试验选用新西兰兔21只,分成3组,每组7只。两组均接受TPN7d,每个组接受其中一种不同的脂质乳剂处理脂乳剂20%(LCT组)和力保脂宁MCT/LCT20%(MCT/LCT组)。第3组为对照组接受口服饮食和接受相同的手术处理静脉注射生理盐水。TPN处理的能量是非蛋白能量418.68kj·kg-1·d-1与40%脂肪所含能量之和。结果表明,血浆胆固醇和甘油三酯有小幅上升。在大脑组织,接受TPN处理组动物的磷脂酰胆碱降低,LCT组的变化更大一些。各组间大脑脂肪酸总体比例分布没有显著差异。脂质乳剂进行TPN处理可引起脑脂质极性馏分的变化,尤其是进行LCT处理的兔子。

给32只美利奴育肥羔羊饲喂大麦秸秆和浓缩料,并分别添加棕榈油(CTRL组)、亚麻籽(+LS组)和单独的槲皮素(+QCT组)或混有亚麻籽的槲皮素(LS+QCT组),来评估其对肉品质的影响。屠宰后,用背最长肌胸段来研究脂肪酸含量,在冷藏条件下将背最长肌切片来测定脂质的稳定性。亚麻籽增加了长链n-3多不饱和脂肪酸(20:5n-3;22:5n-3;22:6n-3)的含量,但与槲皮素一起使用时共轭亚油酸含量显著增加(P<0.05)。此外,添加槲皮素可以减少饱和脂肪酸的比例,添加亚麻籽可以降低肉的脂质过氧化作用。研究表明,在饲喂亚麻籽日粮时,添加槲皮素无论是从营养上还是从商业上(保质期)都是有效的。
