分叉

The basicflows are computed by a low-dimensional Galerkin method.The results confirm thattwo times global mode switching occur with increasing Re up to which the Hopf bifur-cation occurs when the absolutely unstable region cover the whole reversed flow region,and the first explanation of this phenomenon with absolute/convective instability theoryis given.

结果证实了只有当绝对不稳定性区域完全覆盖了回流区才会形成整体的Hopf分叉，此前随着Re数的增加整体模态经历了两次跳跃；并首次用绝对/对流不稳定性理论解释了这一现象。

A muscle-equivalent phantom was used to instead of liver tissue in the experiment. The liver artery of human was simulated by a copper tube with Y bifurcation. Different water flow velocities were maintained in the tube, which are in the typical range of blood flow velocities in liver arteries of human. Copper-constantan thermocouples were used to measure the temperature near the arterial bifurcation.

Species had three kinds of diets during the non-breeding season:(1) mainly invertebrates,(2) mainly fruits, and (3) mainly nectar. This study demonstrated that the diets of 14 passerines during the non-breeding season were significantly correlative with tongue morphology (r=0.424, P .05) and were most correlative with brush length and width of the 3/4 position (r=0.62, P.05). For example, Yuhina brunneiceps's primary diet is nectar and it has the brush-tipped tongue with the longest brush length. Niltava vivida mainly forages for fruits and has a tongue with longer width of the 3/4 position.

十七种鸟类在非生殖季时的食性，亦可分为三大类群：（1）主食无脊椎动物；（2）主食果实；（3）主食花蜜。14种鸟类的舌部形态与其非生殖季食性具有显著相关，其中，仅舌分叉长及3/4位置的舌宽与其食性较有关系，可解释非生殖季食性约36%的解释变异量，也就是分叉长较长的舌头属於刷状卷曲舌形，主食花蜜，以冠羽画眉为代表；3/4位置舌宽较大的舌形，主食果实，以黄腹琉璃为代表。
