In this review we discuss the possibilities and limitations of combining genes from different organisms and the expression of heterologous genes.

本综述中我们讨论了不同有机体基因结合的可能性和局限性以及外源性基因的表达。

Homeobox A segment of DNA found in many so-called homeotic genes concerned with controlling the development of organisms.

同源框：是 DNA 的一个特定片段，存在于一类控制生物体生长发育的同源异型基因上面。

Although the study of a series of genes including the homeotic family has yielded remarkable insight into the molecular mechanisms underlying the development of brain regarding both human and related model organisms, a great number of novel genes remain to be investigated.

虽然含同源异型盒的基因家族等一系列基因在胚胎脑组织的表达特征及有关功能已被阐明，迄今为止，大量与人脑发育、分化相关的基因尚属未知。

烃源岩有机母质均以陆生高等植物输入为主，也有水生生物的输入，反映原始母质具有水生生物和陆源高等植物混源的特征。

While we walked by the side of the river, we saw some kandelia and fiddler crabs, which are very strange organisms.There were some parts of Kandelia look like pens, and the fiddler crabs have very strange claws, one is big and one is small.

我们延溪看到了招潮蟹跟水笔仔，它们都是很奇怪的生物，水笔仔有几个部份长的像笔，招潮蟹的敖一大一小，真奇怪。

During the interglacial period, approximately 5 Mya, sea levels rose and organisms migrated across the narrowest part of this peninsula, the Kra Isthmus.

然而，在古地质事件约五百万年前的间冰期，因海平面上升，使得马来半岛最狭窄的克拉地峡被海水淹没，原本分布在两个隔离海域的生物得以互相交流。

According to the enrichment abilities of the investigated organisms, zooplankton, Crassostrea gigas, Perna viridis, Potamocorbula rubromuscula, Nassarius siquinjorensis and Ulva lactuca were found to be suitable as bio-indictors for some trace metals.

The Institute was established in 1952 and carries out complex limnological studies on streams, rivers, and reservoirs with special attention to the structure of biocoenoses, relations between aquatic organisms and physico-chemical factors of their habitats, and anthropogenic alterations in inland-water ecosystems.

该研究所成立于1952年。主要致力于河流、水库的湖沼学研究，侧重研究生物群落结构、水生生物与其栖息地物化因子间的关系、以及内陆水域生态系统的人类起源等。

Darwin expected species to change slowly, but not at the same rate – some organisms such as Lingula were unchanged since the earliest fossils.

达尔文认为物种变化是缓慢的，但不是以同样的速度变化--一些如海豆芽一样的生物从最早的化石以来未发生改变。

You can snipe the second and third union leaders from this position.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
