The low-dimensional Galerkin method is generalized to solve the flow around arbi-trarily translating circular cylinder.Active control problems of wakes behind circularcylinders are numerically investigated by only small number of modes.The in-line andtransverse oscillation of a circular cylinder with proper frequency produce Karman vor-tex street successfully in some subcritical regime,vhereas the transverse oscillation of acircular cylinder with 1.8 times the natural shedding frequency can effectively suppressthe Karman vortex street at a slightly supercritical Re.
将低维Galerkin方法推广至可以求解任意平移运动圆柱的绕流问题,用较少的模数值研究了圆柱尾迹的主动控制问题,在亚临界Re数下圆柱以适当的频率沿流向和横向振动均成功地激发出Karman涡街;而在略高于临界Re数下圆柱以1.8倍自然脱涡频率沿横向振动明显地抑制了Karman涡街;再现了超临界Re数横向及流向振动圆柱绕流的频率锁定等复杂非线性现象。

Chapter 4 establishes the theory of convex fuzzy mappings: The concepts, such as Jensen's inequality, positively homogeneous, infimal convolution, right scalar multiplication and convex hull are introduced. The corresponding theorems are demonstrated by using the parametric representations of fuzzy numbers. In anti-fuzzy number space, the conjugate mapping of convex fuzzy mapping is concerned, and convexities of conjugate set and conjugate mapping of convex fuzzy mapping are proved. The notions of subgradient, subdifferential, differential with respect to convex fuzzy mappings are investigated, which provides the basis of the theory of fuzzy extremum problems.
在第4章中,建立了有关凸模糊映射的理论:建立了关于凸模糊映射的Jensen不等式、模糊正齐次映射、凸模糊映射的下卷积、右数乘和凸包等概念,利用模糊数的参数化表示,给出了相应的定理;在反模糊数空间,对凸模糊映射的共轭也作了探讨,证明了凸模糊映射的共轭集合和共轭映射都是凸的;最后对凸模糊映射的次梯度、次微分和微分等概念进行了研究,为模糊极值理论打下了基础。

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.
NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量,推测NRP2表达水平高可能有利于提高产仔数,但两品种间表达差异不明显,推测NRP2影响产仔数的关键阶段可能不是猪的发情期;另外,NRP2 是神经轴突介导因子的受体,这些神经轴突转导的信号往往有级联放大的功能,虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大,但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加,从而提高排卵率或产仔数。
