本试验目的是评估肉鸡日粮中添加谷氨酰胺(g.0})和维生素E对其肠道黏膜形态学的作用。试验采取2×3因子(维生素E×g.0}添加时间)的完全随机设计,维生素E添加水平为10和500m./kg.g.0}按3种情况向肉鸡开食日粮中的添加:即不添加、从出壳后头7d内添加和头14d内添加。肉鸡生长期日粮处理仅由维生素E两种添加水平组成。试验肉鸡共1500羽,设6个处理,每个处理分5个重复50羽肉鸡。在出壳后第7、14、21和41天,每个重复随机取2羽肉鸡扑杀,取十二指肠、空肠和回肠样本各5cm.,经处理后测定肠道黏膜绒毛高度和隐窝深度,并用方差分析所得数据,用Tukey氏检验按5%的显著水平比较平均值。结果表明,十二指肠发育最快,随后依次为空肠和回肠,出壳后第41天,日粮添加10m./kg.生素E并再添加1%g.0},对肉鸡肠道黏膜的发育具有促进作用。

The fl.w past a square-section cyl.nder with a g.om.tric disturbance is investig.ted by num.rical.sim.l.tions. The extra term., due to the introduction of m.pping.transform.tion sim.l.ting.the effect of disturbance into the transform.d Navier-Stokes equations, are correctl. derived, and the incorrect ones in the previous l.terature are pointed out and anal.zed. Furtherm.re, the rel.tionship between the vorticity, especial.y on the cyl.nder surface, and the disturbance is derived and expl.ined theoretical.y. The com.utations are perform.d at two Reynol.s num.ers of 100 and 180 and three am.l.tudes of waviness of 0.006, 0.025 and 0.167 with another aim.to expl.re the effects of different Reynol.s num.ers and disturbance on the vortex dynam.cs in the wake and forces on the body. Num.rical.resul.s have shown that, at the m.l. waviness of 0.025, the Kairm.in vortex shedding.is suppressed com.l.tel. for Re = 100, whil. the forced vortex disl.cation is appeared in the near wake at the Reynol.s num.er of 180. The drag.reduction is up to 21.6% at Re = 100 and 25.7% at Re = 180 for the hig. waviness of 0.167 com.ared with the non-wavy cyl.nder. The l.ft and the Strouhal.num.er varied with different Reynol.s num.ers and the wave steepness are al.o obtained.

Dissim.l.r stir wel.ing.（FSW） l.p joints were produced by friction out of Ti6A14V titanium.al.oy and AA2024 al.m.num.al.oy sheets. The joints, wel.ed with varying.tool.rotation and feed rate, were studied by ana- l.zing.the m.xim.m.shear streng.h, Vickers m.crohardness and optical.observations. A dedicated num.rical.m.del. abl. to take into account the presence of the two different al.oys, was used to hig.l.g.t the effects of the process param.ters on tem.erature distribution, strain distribution, and m.terial.fl.w. The com.ined anal.sis of experim.ntal.m.asurem.nts and num.rical.predictions al.owed expl.ining.the effects of tool.rotation and feed rate on the m.terial.fl.w. It was found that tool.rotation had a l.rg.r im.act on the joint effectiveness with respect to feed rate. A com.etition between m.terial.m.xing.and heat input occurs with increasing.tool.rotation, resul.ing.in hig.er joint streng.h when l.wer val.es of tool.rotation are used.
