The results demonstrated that the ITS sequence analysis supported the identification based on morphological characteristics for most of species of Amanita on the species level or on the genus level.

在这种情况下，如能借助分子手段，以传统的形态特征为基本分类依据，辅以DNA序列比较分析，同时借助国际核酸数据库的大量信息资源势必将有助于鹅膏属真菌的准确鉴定。

Abstract:Seven species of Amanita, collected in Lishui of Zhejiang Province, China, were identified primarily based on morphological characteristics. The rDNA ITS regions of these species were cloned and sequenced, and the characteristics of ITS sequences were compared and analysed.

常规对像鹅膏菌属大型真菌的分类鉴定主要是依据子实体的形态，颜色，气味，以及孢子特征等，这些形态特征经常是易变的，模糊的，易混淆的，因而依据传统的形态特征进行分类鉴定总是带有一定的局限性和主观性，要准确鉴定鹅膏属真菌到某一个种实属困难。

A species of monkey living in north-western Amazonia was named earlier this year - and scientists immediately called for it to be placed on the endangered species list.

2008年初，科学家在亚马逊河流域西北部发现一种新猴子，并随即将它们列入濒危物种名单。

Americium has lots of species in aquatic solution. It is difficult to measure the distribution of americium species while they can be calculated by many geochemical software.

Am在水溶液中的形态分布复杂，直接测量困难，使用相关软件依据热力学常数推算核素的形态分布简单可行。

It is used in solving species solubility,especially some nuclide Am, U, Pu,Np,Th, Ra,Te, and so on. This paper calculates species contribution of Americium by use of EQ3NR code.

本文以核素镅为例，计算了镅在水溶相中的存在形式，并模拟计算了不同pH值和不同∑CO3浓度条件下镅物种的化学形态分布优势。

The result showed that newwheat species might be prodcued in progeny of unstable amphidiploid, which offeredsignificant pattern for evolution from octaploid wheat to hexaploid wheat and widenedthe train of thought of studying the origin of biological species.

这个结果显示，通过对双二倍体分离后代的有效选择，有可能形成一个新的小麦种，从而为从八倍体小麦向六倍体小麦演化提供了一个新的进化模式，拓宽了研究物种起源的思路。

Except Ananas comosus, which is regarded as fruiter, other species have ornamental value. For example, the tank Bromeliads and silver-leaf tillandsia have already become new species in the international market.

除菠萝外，其它种类都具有较大的观赏价值，其中积水型凤梨和铁兰银叶种已成为国际市场上的新型花卉。
