| 1 | Computer Modeling: an Important Tool in Materials Processing显示文摘The development of techniques to control and use materials, especially metallic materials continues to play a key role in the technological advancement of modem day society. A variety of materials processes have been developed overtime, and are applied to design and fabricate products. Heat treatment of metallic materials has been the method of choice applied to improve mechanical properties such as strength, hardness, and toughness, as well as to improve the homogeneity of properties in materials such as corrosion resistance. The molt significant success stories in the application of materials processes involve the heat-treatment of steel. The reasons for this largely lie in the ease with which steel microstructures can be altered by controlled heating and cooling. The objective of computer modeling of materials processes is to maximize on the beneficial factors while keeping to a minimum the negating effects such as components distortion and residual stresses. Computer modeling is a powerful tool in achieving this objective in the sense that with it, the effect of parameters associated with materials processes can be analyzed systematically in order to optimize them before actual production begins. | L.L Meekisho, X Chen Portland State University, P0 Box 751, Portland, Oregon 97207 USA Automated Analysis Corporation, Peoria, IL USA | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 10 |
| 2 | 取食转基因抗虫棉上的棉蚜对粉舞蛛存活和发育的影响显示文摘本文以转双价基因棉花SGK321、棉蚜Aphis gossypii和粉舞蛛Alopecosa pulverulenta为对象,研究了捕食转基因植物上的植食性害虫对多食性捕食性天敌的影响。结果表明,粉舞蛛可以猎食棉蚜,但单独捕食棉蚜不足以长期维持若蛛的生存和发育;与果蝇混合饲养,能显著提高若蛛存活率和体重。在猎物过量或数量不足的情况下,单独捕食转基因棉或常规棉上的棉蚜,若蛛的生存曲线和体重差异不显著。在猎物过量的条件下,用转基因棉上的棉蚜与果蝇混合饲养,若蛛的存活率显著高于用常规棉上的棉蚜与果蝇混合的处理;但这两种处理下,若蛛的体重差异不显著。在猎物数量不足的情况下,用转基因棉或常规棉上的棉蚜与果蝇混合饲养,若蛛的存活率和体重差异都不显著。可见,转双价基因棉花SGK321上的棉蚜对粉舞蛛的存活和发育没有显著的不利影响。 | 郭建英 Gabor L.LVEI 万方浩 韩召军 | 2006 | 昆虫学报2006，49，5： | 10 |

| 4 | Branched chain amino acids alter fatty acid profile in colostrum of sows fed a high fat diet显示文摘Background:Branched chain amino acids(BCAAs)are important substrates for milk protein synthesis in the mammary gland,and are tightly related to lipid metabolism.No study has been performed examining the role of BCAAs with high fat diets on milk fat synthesis.This study was designed to investigate the effect of dietary BCAAs on growth performance of piglets,progeny body weight,and milk fat composition in sows fed a high fat diet.Four diets(CON=control diet;HF=high fat diet with 8%soybean oil;HF-MB=HF plus 0.39%BCAAs;HF-HB=HF plus 0.78%BCAAs)were fed to sows from late gestation to weaning.Results:Compared to HF,BCAAs(HF-MB and HF-HB)increased the litter weight(P<0.05)and overall litter weight gain(P<0.05)at weaning and increased colostrum fat content by 27.3–35.8%(P<0.01).Fatty acid profiles between the two doses of BCAAs were similar.Compared with HF,HF-MB tended to decrease the percentage of C18:3n3(P=0.063)and increased the percentage of C18:1n9c(P=0.03).In addition,BCAAs in HF-MB increased the concentration of total fatty acid by 22.1%in colostrum(P=0.03)but decreased that in serum at parturition by 53.2%(P=0.027).The fatty acids in colostrum that increased with BCAAs were C15:0,C17:0,C20:3n6,C20:4n6,C20:5n3 and C22:6n3(P=0.00~0.04).Colostrum fatty acids of C20:0,C21:0,C22:0,C16:1,C20:1,C18:1n9c also tended to be increased(0.05 | Chang Ma Yajng Liu Shaoshuai Liu Crystal L.Lévesque Fengqi Zhao Jindong Yin Bing Dong | 2020 | Journal of Animal Science and Biotechnology2020，11，2： | 3 |
