Template-confined growth is a very powerful method for obtaining aligned 1D nanomaterials with adjustable diameter, length and morphology. Porous anodic aluminum oxide templates with different channel structures have been synthesized in our lab, with which the aligned CNT arrays, Y-branching and novel dendriform CNTs have been obtained. Based on the structural characterization of the products, a space-limited and self-catalytic growth mechanism has been proposed accordingly. Roughly speaking, the catalyst particles at the bottom of template channels initiate the nucleation of carbon species, which acts as the seed for subsequent CNT growth.

本文采用近年发展起来的模板控制生长法，以多孔氧化铝模板控制CVD生长的方法调控了碳纳米管有序阵列、γ-分叉及树枝状分叉结构，在对产物进行详尽结构表征和分析的基础上阐述了氧化铝模板控制生长碳纳米管的生长机制：孔道内催化剂仅在生长初始阶段催化碳物种的成核，起&种子&作用，随后模板孔道自身的催化及限域作用使碳纳米管紧贴着孔道内壁生长。

For what I did before, they always can be done by hard studying and working, but it doesn't work for trading at all, seems trading always tends to break out the guideline of my knowledge, experience and statistic.I thought I was going to be a good trader 6 months ago, but now I doubt it, I never feel such despairing that the opportunity is right in my hand but I just could not make it and all.

想象，生命是一棵顺着时间盘绕而上的参天大树，每个分叉都是一个选择，而人生的悲哀在于在每个分叉口只能选择一次，回不了头也永远不会知道在其它成千上万的枝干上可能发生的快乐或是悲伤，于是在抉择中彷徨，在对错中迷茫。

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.

实验采用一种等效微波体模来代替肝组织；采用Y型铜管代替人体肝动脉内的分叉大血管，并依据人体肝动脉的血流速度调节管内的水流速度；利用铜-康铜热电偶测量分叉血管周围的温度场。

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。
