Through all this test analyse Pathogenicity and Immunological status of ALV-J Inner Mongolia strain, the result showed the infected chickens began to have pathological change of Myelcytomatosis at 3-week: the main pathological changes of acidophile myelocyte were found in bone marrow and between cardiac muscle fibers,and there were many granules in the hyalotome.This kind of oncocyte proliferated in every tissue at different amount, but the cells that proliferated in bone marrow, cardiac muscle fiber, oarium were much more than other tissue, and they often developed neoplasma. At same condition,there were no abnormalty advent in control group, In immunological aspect: the increase of lymphokine and ANAE positive cells showed cell-mediated immunity was strengthend during antineoplastic infection; the emergence of ALV-J antibody of ELISA suggest there was humoral immunity exist at the same time.
结果显示:脾脏PCR检测结果表明1、2两实验组均有阳性病例出现,而对照组全部为阴性,说明实验鸡体内已有ALV-J内蒙株感染;接种病毒后3周龄开始出现骨髓细胞瘤病的病理变化:肝脏、脾脏有程度不同的肿大,镜下观察,骨髓内最早出现了与骨髓细胞相似、形态基本一致的大型圆形或椭圆形、胞核较大多为椭圆形、胞浆内含有大量嗜酸性圆形颗粒的髓细胞样瘤细胞增生,随后通过血流瘤细胞可转移到肝脏、心肌、卵巢或睾丸等组织并形成肿瘤性病灶,而对照组没有出现明显病变;免疫状态方面:以脾脏淋巴因子和ANAE阳性细胞增多说明细胞免疫在抗肿瘤感染过程中增强,ELISA检验实验鸡抗体出现阳性的结果表明同时也存在着体液免疫。

If it is a mistake to justify human selfishness on the basis of the alleged selfishness of nature (as one strain of "Social Darwinism" tried to do in the late 19th and early 20th centuries, and some right-wing columnists do now), then it is equally mistaken to espouse altruism merely on the basis that chimps can be assiduous at sharing food and at being good buddies to one another.
如果在所谓的自私属性的基础上纠正人类的自私性是个错误(正如19世纪末20世纪初社会达尔文主义的一种歪曲和一些右翼专栏评论员目前的做法那样),那么将利他性嫁接到猩猩会总是与同类分享食物,和平友好的观点之上,也同样是个错误。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400~450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.
压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相;高效熔体处理显著改善了材料的冶金缺陷的存在形态,使含杂量明显减少、夹杂物尺寸变细小且分布均匀,富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物,同时也明显细化了结晶组织;此外,由于高效熔体处理有效地减少了材料中裂纹萌生源数量,因而改变了材料的塑性变形微观过程及断裂方式,主要以单滑移和交滑移进行塑性变形,断裂方式为穿晶微孔聚集型,韧性断裂前产生了大量的均匀变形,不易出现变形失稳,从而显著提高了罐用铝材的塑变能力和力学性能。
