ABSTRACT Amphioxus, a cephalochordate, is the closest living relative to vertebrate, and has been widely known as the most important animal to study the origin and evolution of vertebrates.

文昌鱼是介于无脊椎动物和脊椎动物之间的过渡类型，是研究动物进化和胚胎发育的典型材料。

There some biotite granites belong to the transitional granite between I-and S-type.

同时有一些黑云母花岗岩属于I型和S型之间的过渡类型。

Several results have been achieved as followings: 1. The response of stable carbon isotope in karst cave system to surface climate and environment This index can distinguish origin forest from other vegetation, but cannot distinguish transitional eco-environment such as bosk, grassplot and rocky desertification.

洞穴系统稳定碳同位素对地表气候环境的响应通过对4个不同生境洞穴系统的研究，认为洞穴系统稳定碳同位素可以很好地将原始森林植被同其它植被类型区分开；但是不能很好地区分植被退化的过渡类型如灌丛、草坡以及石漠化等。

In particular, the morphology and distribution of the feathers on Liaoning dromaesaurids, among other features, strongly suggest that dromaeosaurids might have been able to parachute or even glide, representing a group of transitional animals between the cursorial non-avian theropods and volant birds.

尤其重要的是，通过分析辽宁奔龙类化石保存的羽毛形态和分布情况，本文认为这些动物可能具有降落甚至滑翔能力，它们代表地栖的非鸟类兽脚类恐龙和会飞的鸟类之间的过渡类型。

All of the traits suggest that dinoflagellate maybe is the intermediate species between prokaryotes and eukaryotes.

寇氏隐甲藻细胞超微结构的特殊性表明，这个物种可能是原核生物向真核生物进化的中间过渡类型。

Thus an intermediate phenotype will be produced in the heterozygote.

这样在杂合体中就存在中间过渡类型。

Consisted of single, double vascular bundle, transition types between them, but given priority to double vascular bundle; the epidermal cell consisted of cutin layer; the hypodermis consisted of typical two-layer of parenchyma cells arranged continuously or discontinuously.

云南松针叶的维管束以双维管束为主，同时亦有单维管束以及介于单、双维管束之间的过渡类型；皮下层为典型的二型皮下层；表皮层的角质层明显；树脂道多为典型的外生型。

Its rock types are more complicated, which include siliceous rocks、mudstones、clastic rocks、carbonate rocks and transitional rock types between them.

岩石类型也很复杂，包括硅质岩、泥岩、碎屑岩、碳酸盐岩及其过渡类型的岩石。

The results showed: 1 Plain Prinia had six song types, four were frequent, one transitional and one scarce type.

结果如下：⑴共采集到620个鸣句，分属6种鸣句类型，其中4中为常见类型，1种为过渡类型，1种少见类型。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
