Thousands of amoebas act together like one, like minions to their chemical messenger overlord, eventually even morphing into weird tree-like structures that allow a few lucky individuals to escape as spores to better and more fruitful lands.

成千上万的变形虫像个人样起行动，就像它们的化学信使霸主的爪牙，最终甚至变成奇怪的树状结构，让些幸运的个体作为孢子逃往更好、更肥沃的土地。

Valente and his colleagues used genetic data to build a tree of New Zealand's living and extinct native birds.

瓦伦蒂和同基因数据建立了新西兰现存和已灭本土鸟类的树状图。

But one day, while out in the forest, the husband discovered a stump that looked like a child.

但有天，丈夫在森林里发现了个看起来像个孩子的树状。

First are these dendriform columns. Dendriform means tree like.

首先这些树状柱。树状的意思树状的。

Even though this basic structure is the same across species, the spicules then take many different shapes, such as pointy needles, branched trees, or spiked spheres.

尽管这种基本结构在不同物种中相同的，棘刺却呈现出多种不同的形状， 如尖针、分枝树状或带刺的球体。

For this reason, this data is distributed across many DNS servers, which are authorities for different parts of the tree.

因此，这些数据分布在许多DNS服务器上，它们树状结构不同部分的权威来源。

The simple tree above represents a constituent of category A which is composed of two parts, one of category B and the other of category C, occurring in that order.

上述简单的树状图表示个A类的构成成分，它由B类和C类的两部分按顺序组成。

Thus, the design method proposed in this study can solve the optimal problems of tree-type irrigation pipe networks with varying topologies.

因此，本研究提出的设计方法能够解决拓扑结构多变的树状灌溉管网优化问题。

The optimal design of tree-type irrigation pipe networks is a key aspect regarding the profitability of irrigated agriculture.

树状灌溉管网的最优设计影响灌溉农业效益的关键环节。

Tree-Type Irrigation Pipe Network Planning and Design Method Using ICSO-ASV Research on tree-type irrigation pipe networks is an important component of agricultural water-saving projects.

树状灌溉管网规划与设计方法——基于ICSO-ASV的研究，农业节水工程中的重要组成部分。树状灌溉管网的优化设计，对于提升灌溉农业的经济效益具有关键作。
