     Meanwhile,the effects of some key factors related to the extract rate of chlorogenic acid were mainly investigated. The results showed that the optimal conditions were as follows: countercurrent extraction of 4 levels,pH 3.5 at 80 ℃,with 1∶20 as the original ratio of material to solvent,and 30 min,20 min,15 min or 10 min as extracting time in respective gradient level.

An 2×5 factorial experiment was conducted to examine: (1)the effect of gradient levels of commercial black locust(Robinia pseudoacacia L.) leaf meal (BLM) used in diets on growth performance of meat-type rabbits, (2) the response from different genotype rabbits(Harbin white rabbit, H and Danish white ranbbit, D) to diets including BLM. Ninety-five H rabbits,eighty-five D rabbits both weaning at 30±2 days of age were allotted to accept the diet treatments with an inclusion of 0%, 10%, 20%, 30%, 40%BLM,...

An 2×5 factorial experiment was conducted to examine: (1)the effect of gradient levels of commercial black locust(Robinia pseudoacacia L.) leaf meal (BLM) used in diets on growth performance of meat-type rabbits, (2) the response from different genotype rabbits(Harbin white rabbit, H and Danish white ranbbit, D) to diets including BLM. Ninety-five H rabbits,eighty-five D rabbits both weaning at 30±2 days of age were allotted to accept the diet treatments with an inclusion of 0%, 10%, 20%, 30%, 40%BLM, respectively, each treatment with 4 replicates. Results showed that the incorporation of 10%~40% BLM into diets had no influence on both rabbit mortality and diet palatability,but a marked adverse effect on growth performance,namely that average daily body gain(ADG) was decreased following a cubic pattern(R2=0.85,P<0.05), feed intake(FI) and feed conversion ratio(FCR)increased also both following a cubic pattern(R2=0.96, P<0.01 for FI, R2=0.95, P<0.01 for FCR) with increasing BLM level from 0% to 40%. Compared to diet treatments with 0% and 10% BLM, 20% inclusion of BLM and the above,significantly decreased ADG and increased FI (P<0.05), extremely elevated FCR (P<0.01). There was no difference on the tolerance to BLM diets between genotypes. It was recommended that BLM was formulated into growing rabbit diet at the level of 10%.

本试验采用2×5因子设计,研究日粮中不同水平刺槐叶粉水平(0%、10%、20%、30%、40%)对肉兔生产性能的影响及不同肉兔品种(哈尔滨白兔即H兔、丹麦白兔即D兔)对刺槐叶粉日粮的反应。选用30±2日龄断奶H兔95只、D兔85只,分别按体重、窝别、性别分成10个处理,每处理4重复。试验结果表明:10%~40%的刺槐叶粉用量对肉兔健康无影响且无适口性问题,但叶粉用量对肉兔生产性能有明显的负面剂量效应影响,即引起增重呈显著的三次曲线下降(R2=0.85,P<0.05)、采食量和饲料/增重呈极显著三次曲线上升(R2=0.96、0.95,P<0.01)。日粮中刺槐叶水平20%或20%以上,显著降低日增重、增加采食量(P<0.05),极显著降低饲料效率(P<0.01)。对刺槐叶粉日粮的耐受性没有品种差异(P>0.15),日粮中叶粉配合比例以10%为宜。

Watershed transform is an efficient way to segment image;however,it often results in over-segmentation.Usually,smoothing pre-filtering is adopted to avoid over-segmentation,but the positions of the segmented regional contours may be incorrect.For the purpose of segmenting image without over-segmentation and without position errors of regional contours,a method for watershed segmentation is proposed based on viscous morphological gradient modification.First,original image is transformed by morphological gradient transform,and then viscous morphological operators with structure elements of different sizes are used to modify the relief surface of gradient image;after modification,most irregular local minimums caused by details and noise are removed,while positions of regional contours are not or slightly changed due to the less modification of the high gradient levels.Finally,standard watershed transform is employed to implement segmentation on the basis of modified gradient image.Experiments show that this method not only effectively avoids the over-segmentation of watershed,but also preserves the positions of regional contours.

分水岭变换是一种有效的图像分割方法,但存在过分割现象,尽管应用预平滑处理可以减轻或消除过分割,但却容易使分割后的区域轮廓发生位置偏移,为此,文中首先对图像进行形态学梯度变换,然后运用粘性形态学运算对梯度图像进行地貌修正,在消除产生过分割的非规则局部极小值的同时,保持区域轮廓的位置不变,最后在梯度修正图像的基础上,运用标准分水岭变换实现图像分割。仿真实验表明,该方法不仅能有效地消除过分割,而且具有较强的区域轮廓定位能力。
