The colored patterns on arbitrary cut plane is an important method in 3D data-field visualization of finite element.By using the technology of the Object-Oriented Programming and the method of scan-line,the colored patterns on arbitrary cut plane are given.The example by the OPENGL of Visual C++ R6 can support the theory satisfactorily.     

软包装调味笋的研制

对软包装调味笋加工的色泽和口感进行研究。研究表明,用质量分数为0.005%的NaH SO3溶液预处理原料,用质量分数为0.1%的CaCl2溶液预煮杀青10m in,并用0.15%的醋酸浸泡30m in,焖煮时间控制在5m in,就能较好地保持新鲜笋的色泽,同时兼顾产品较高脆性和较好的滋味,达到良好口感的需要。     

基于HIS颜色特征的田间成熟番茄识别技术

研究了一种基于HIS颜色特征的田间成熟番茄识别技术。将计算机视觉系统获取的番茄RGB图像转换成HIS图像，通过统计H、I、S分量的灰度分布找出成熟番茄、未成熟番茄和叶子(枝干)灰度分布差别；然后根据H分量的灰度分布用阈值法分割出成熟番茄区域；经过空洞填充后，计算出番茄质心坐标。该方法对田间成熟番茄之间相互分离的情况有很好的识别效果。     

计算机视觉描述缺素番茄叶片颜色变化的研究

利用计算机视觉系统代替人眼对番茄缺素进行自动识别的方法，通过对缺素番茄叶片彩色图像的分析研究，利用图像处理技术中的颜色分析方法，分析缺N和正常叶片的特征量随着缺素时间的变化规律．提出用G体均值、H色调均值来定量描述缺N叶片随时间的变化。结果表明：利用计算机视觉能定量描述缺N叶片颜色随缺素时间的变化。     

玉米籽粒内部组分低对比度透射图像精确分割研究

为解决玉米籽粒透射图像由于对比度较低造成内部组分提取不精确的问题,提出一种基于色彩通道非线性变换的多通道重叠区域分割方法,对玉米籽粒图像在灰度、R通道及b通道下得到的二值图像使用重叠区域原理,实现玉米籽粒组分的精确分割。首先,采集不同玉米品种的籽粒透射图像,提取单粒玉米籽粒;其次,采用多通道重叠区域法分割单粒籽粒图像,得到玉米籽粒胚部、角质胚乳和粉质胚乳3部分的图像;最后,以查全率和查准率评价多通道重叠区域法与传统图像分割方法对不同品种玉米籽粒的分割效果。不同品种玉米籽粒的分割试验表明:多通道重叠区域分割方法的查全率、查准率及综合评价指标均达到98%以上,分割效果优于传统的图像分割方法,能够实现不同品种透明角质玉米籽粒透射图像的精确组分分割。

Allele frequencies of the extension locus encoding the melanocortin-1 receptor in Japanese and Korean cattle

In order to estimate the influence of the Extension (E) locus in cattle coat color, the melanocortin‐1 receptor (MC1R) gene in Japanese Black, Japanese Brown and Korean (Hanwoo) cattle were sequenced. The sequences of the coding region revealed three alleles (E^D, E⁺ and e), which were previously reported. Polymerase chain reaction‐restriction fragment length polymorphism was performed to investigate the gene frequencies of the three breeds. Japanese Black was almost composed of E^D and E⁺ individuals, E^D = 0.481 and E⁺ = 0.514, and no homozygous e/e, therefore that is consistent with the hypothesis that E^D and E⁺ induce black pigment synthesis. Allele frequencies between Japanese Brown and Hanwoo were obviously different; however, recessive red e allele frequency was 0.038 for Japanese Brown and 0.948 for Hanwoo, even though both breeds have quite similar coat colors (ranging from yellowish brown to dark brown including a red coat color). This result suggested that other genes are also associated with a coat color of red and brown in cattle.     

COLOR DOPPLER ULTRASONOGRAPHY IN PREDICTION OF THE REDUCIBILITY OF INTUSSUSCEPTED BOWEL IN 15 YOUNG DOGS

Color Doppler ultrasonography was performed in 15 young dogs with intestinal intussusception to test the hypothesis that color Doppler findings can be used as a predictor of the manual reducibility of the intussusception at celiotomy. Color flow Doppler ultrasonography indicated blood flow within mesentery of the intussuscepted bowel in 12 of 15 dogs and reduction was achieved in nine of these 12 dogs (75%). In the remaining three dogs and in three dogs where no color Doppler signal were observed, an irreducible intussusception was confirmed at celiotomy. Color Doppler ultrasonography is a useful method for predicting the reducibility of intussusception in dogs.     

半番鸭羽色性状AFLP标记初步研究

本研究初步利用AFLP标记对半番鸭及其母本-北京鸭进行检测。结果显示,AFLP标记扩增带丰富,10对引物组合共检测到2046条扩增带,平均每对引物组合/每个池DNA可产生60.15条。半番鸭白羽性状特有的扩增带共有15条,分布在E AAC/M CTA、E AAC/M CTT、E AAG/M CAG、E ACA/M CTC、E ACT/M CTA和E ACT/M CTC等6对引物组合上,为半番鸭个体羽色与AFLP标记相关分析和验证提供了素材。     

补饲青绿饲料对不同性别肉仔鸡皮肤色泽的影响

研究了在饲喂全价配合日粮基础上补饲青绿饲料对不同性别肉仔鸡全身不同部位皮肤色泽的影响。各组自由采食玉米-豆粕型基础日粮,分别于第1、15、29天开始补饲青绿饲料,比较分析42日龄时的全身各部位皮肤的色泽(L、a、b值)。结果表明,不同性别肉仔鸡各部位皮肤色泽间存在一定的差异性;补饲青绿饲料对肉仔鸡皮肤色泽的影响效应,以黄度最强和亮度最弱;补饲青绿饲料的时间越早,对肉仔鸡皮肤色泽的影响越明显;补饲青绿饲料对母肉仔鸡皮肤色泽的影响比对公肉仔鸡更显著。
