棕榈藤是棕榈科的藤本植物，天然分布于热带和亚热带森林中，其生长对水分要求较高，据研究，水分是棕榈藤生长的第一影响因子。

ABSTRACT Rattan is a group of climbing plants belonging to the family of Palmae, occurring naturally in different forests in tropical and subtropical areas.

棕榈藤是棕榈科的藤本植物，天然分布于热带和亚热带森林中，其生长对水分要求较高，据研究，水分是棕榈藤生长的第一影响因子。

Areca catechu , of which areca nut is a fruit , is one of the palm species and contents several nutrients as well as many pharmacologically active compounds .

槟榔是棕榈科植物槟榔的干燥成熟种子，含有多种人体所需的营养元素以及多种生理活性成分，是一种常用的中药。

"The betel nut is the seed of the areca, or betel, palm, family Palmae; the betel leaf is from the betel pepper, or pan plant, family Piperaceae."

槟榔子是棕榈科槟榔树的种子；而槟榔叶是槟榔胡椒，或科蒟的叶。

The surprising finding was that local plantations of areca palms retained 90% of the birds associated with native forest.

令人惊讶的发现是，当地棕榈科槟榔属植物的种植保留了90 ％与天然森林相伴的鸟类。

The coconut is the fruit of the coconut palm, of the genus Arecacecae.

In the majority of cases, multiple clones from individuals resolved as monophyletic, which suggests that different copies of ITS not completely synchronized evolution, the same species of plant palm plants ITS sequences, sometimes far greater than differences between species of palm plants, However, the high levels of homoplasy in the ITS dataset, led to concerns that topologies obtained from these data might be unreliable; 2 Determination of the original 11 categories of Chinese palm plants matK sequences, and comparison with other 8 Chinese palm matK sequence from the NCBI GenBank database.

结果表明：部分棕榈科植物ITS序列种内差异较大，提示其不同ITS拷贝间没有完全实现同步进化，同种棕榈科植物植物ITS序列差异，有时候大于非同种棕榈植物间差异，这种情况下，由ITS序列构建的棕榈科植物系统树可能是不可信的； 2测定了11种中国原生棕榈科植物matK序列，并通过NCBI网站对GenBank数据库检索得到了其它8种中国原生棕榈科植物matK序列。

The results showed that palm plants matK sequence information of certain points, but more conservative; 3 In all, 19 species representing 15 genera in palmae were examined.

结果显示，棕榈科植物的matK序列存在一定的信息位点，但是较为保守； 3总的来说，19种样品代表了15属棕榈科植物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
