A warning signal from the system which indicates high EC or EC ratio of a dairy cow is used to inform the milker to pay attention to the suspected cow. The detection thresholds of EC and ECR to determine whether a quarter or a dairy cow is infected with mastitis correspond with the criterion of SCC = 500×103 cells/ml for quarter foremilk of a dairy cow. The performance of online system for mastitis detection in dairy cows is evaluated with several methods, such as the detection thresholds, running analysis and discrimination analysis.

Ever since Mr Murdoch began to stalk the Journal, the news media has been singing with stories of his barbarities. How he habitually breaks his promises that he will protect journalistic independence. How he uses his media empire to advance his business interests or pursue personal feuds. How he fills his British tabloids with topless girls and bombastic headlines. How he kowtows to the Chinese government.

自从默多克先生开始对《日报》虎视眈眈以来，新闻媒体就高调披露他的粗暴手法，包括他如何习惯性地违背自己保护新闻独立的承诺；他如何使用旗下的传媒帝国来实现自己的商业利益或公报私仇；他如何让袒胸露乳的性感女郎和言过其实的头条新闻登上自己掌控的英国八卦媒体；以及他如何屈服于中国政府的压力。

Cheese is the fresh or mature fermented milk product made by cow or ewe milk, cream, partly degreased milk, buttermilk or the mixture of all these added with proper lactobacillus and rennin, through clabbering and whey segregating.

奶酪是以牛乳或羊乳、奶油、部分脱脂乳、酪乳或这些产品的混合物为原料，加入适量乳酸菌和凝乳酶，经凝乳并分离乳清而制得的新鲜或发酵成熟的乳制品。

Microstructures of the two inbred lines in 3、5、7、10、15、20 and 25 DAP seven stages during endosperm development showed that endosperms were in the stage of cell division in 10 DAP,then endosperm cells accumulated substances rapidly.In 20 DAP,endosperm cells were filled with starch grains.The endosperm structure was also different between the two inbreds, hard and soft endosperm for N04 and Dan232,respectively.

两个自交系胚乳发育的显微结构观察发现，N04和丹232在10 DAP处于细胞分裂阶段，之后胚乳细胞内含物快速增长，20 DAP胚乳细胞充满淀粉粒。N04胚乳发育成硬质型，丹232胚乳发育成粉质型，两个自交系的胚乳结构存在较大差异。

The seed embryoes were penetrated by 〓 ion beams of 75 MeV/u and the seed endosperms were implanted by the proper degraded 〓 ions, and soluble protein of the seedling in M1 generation was divided into 5 sections to analyze their changes at different molecular weight. 1 In comparison with control, the relative content of the second section (molecular weight is heavier in all sections) of all irradiated materials got down, while the relative content of the fifth section (molecular weight is the lightest) of those went up. 2 The penetrating seeds made the relative content of the first section (molecular weight is the heaviest) and the third section (mid-molecular weight) drop, while the fourth section went up. Moreover, the changes of the third section and the fourth section of the penetrated materials were clearly different from those of the implanted materials. 3 The difference between implanted embryo and implanted endosperm existed in deeper dropping of the first section and higher rising of the fifth section on relative content of soluble protein of the latter. 4 On irradiated materials at lower doses, there were exceptional changes of soluble protein, it may be thought that there was excited effect of low dose.

1.75MeV／u 〓O〓离子经过适当降能后注入小麦种子的不同部位和贯穿整个种子，对其M1代幼苗的可溶性蛋白质组分以及电泳中不同区段蛋白质组分相对含量加以分析，结果表明：1）同对照相比，随着辐照剂量的增加，所有辐照材料第二区段蛋白质组分的相对含量下降；而第五区段蛋白质组分的相对含量升高。2）种子的贯穿处理，同时也引起第一区段和第三区段蛋白质组分相对含量的下降以及第四区段的升高；其中第三、四区段的变化明显区别于注入效应。3）注入胚和胚乳的区别在于后者第一区段蛋白质组分相对含量的较大下降和第五区段的较大提高。4）小剂量辐照的材料，可溶性蛋白质组分的变化异常，可能与低剂量辐射兴奋效应有关。

The high performance of FcRn mRNA in piglets within 3d age was consistant with the timing of their peak absorption of colostrum and that of "gut-closure",and was also testified by the detection of changes of serum IgG level in piglet showing a close correlation with FcRn expression,which illustrated the critical importance of FcRn presence to the acquisition of effective passive immunity in newborn animals.

而FcRn mRNA在仔猪出生后3d内的高表达与新生仔猪吸收初乳的高峰时间及&肠关闭&时间相吻合，对仔猪血清IgG水平的检测也显示了新生仔猪IgG含量峰值的出现与FcRn在小肠的高表达存在一致性，说明了FcRn对新生动物获取足够被动免疫的重要性。
