This paper researched the behaviors and time budgets of captive - bred chinese alligator , and discussed the taxonomical status of chinese alligator ( alligator sinensis ) and the phylogeny of the reptiles based on the sequences of nt - 3 and bdnf genes 本論文對涉及飼養條件下夏秋兩季揚子鱷的行為和活動時間分配進行了研究,同時基于nt - 3和bdnf基因部分序列探討了揚子鱷的分類地位和爬行動物的系統發生。

The sequence analysis showed that the identities of alligator sinensis dmrt1 gene to human dmrt1 gene in the dna sequence and the amino acid sequence were 87 % and 95 % , respectively . the results indicated that dmrt genes were highly conservative in phylogeny ( 3 )測序結果表明,雌雄揚子鱷dmrt1基因的序列一致,且其dna序列和編碼的氨基酸序列與人相應dmrt1基因的相似性分別為87 %和95 % 。

Firstly , analysis erp theories principle , phylogeny and latest development , research the relationship between erp and dss , olap , data warehouse , moreover argue and study on the necessary of putting erp into practice at electronic commerce epoch 首先對erp的理論原理、發展歷史及最新進展進行了分析,研究了erp與dss 、 olap 、數據倉庫的關系,并對電子商務時代實施erp的必要性進行了研究和探討。

Some differences between species were found , which can be used lor the identification to subdivision of the genus and supraspecific taxon , furthermore , their structural diversity provided taxonomic evidence and valuable information for phylogeny of the genus 五味子屬植物在種子形態特征上存在一定的差異,可為屬以下、種以上的分類提供依據。

1 . it is proved that stock company can be used in the management of chinese expressway from the characteristic of expressway , the phylogeny of stock company and the exprenices of expressway stock system in other countries 本文的主要工作如下: 1從高速公路的特點和股份制的發展歷史、目前國際上高速公路股份制現狀說明了高速公路股份制的可行性。

Through comparison and alignment on the sequences , 47 haplotypes are chosen and involved in analysis . 4 . the purposes of this research are phylogeny of intrafamily ( including intraspecific , interspecific , intergeneritic and intersubfamily ) 經排序和對比分析,能夠用于分子系統學分析的單倍型序列有47條,這些單倍型全部參加了分析。

As a considerably large amount of dna sequences become increasingly available , they are widely used to study phylogeny of species and multigene families , as well as the mechanism of evolution at molecular level 基于相當大量的dna序列的獲得,其被廣泛地用于物種的系統發生、多基因家族的演化,以及在分子水平上的進化機制的研究。

It is a period of an epochal turn in chinese movie phylogeny and chinese movie exploring the maturity from 1931 to 1949 , which has exerted a tremendous influence on the later development 摘要1931年至1949年,是中國電影發展史上具有劃時代轉折意義的一個時期,是中國電影在探索中走向成熟的時期,并對以后的發展產生了深遠影響。

Four monophyletic groups have traditionally been united as myriapoda , namely chilopoda , pauropoda , diplopoda and symphyla . the relationships of myriapods are central to most questions in higher - level arthropod phylogeny 現生的多足動物主要由唇足綱、綜合綱、少足綱和倍足綱四個單系群組成。

The results showed : ( 1 ) the forming sequence of the cortex plate in different types cortex in goat fetus is from paleocortex and neocortex to archicortex , which is contray to the law of phylogeny 不同類型大腦皮質皮質板的分化順序為古皮質舊皮質新皮質,與種系發生的順序相符。

On this account , the general morphologic structure character of nervous system reflects the adaptation to environment and has little relation with the phylogeny of animal 因此,神經系統的一般形態結構特征更多的是反映動物對環境的適應性表現,而與神經系統的進化程度關系較小。

From among the phylogeny of entire western political philosophy , the kindness and justice , kernel concepts of moral preestablishing , experienced a gradually evolving process 從整個西方政治哲學發展史看,道德預設的核心概念“善”和“正義”經過了一個逐漸演化的過程。

Most of it can be identified as repetitive elements that have no known biological function ( although they are useful to geneticists for analyzing lineage and phylogeny ) 它們多數被認為是沒有熟知的生物學功能的重復元素(盡管它們對遺傳學家分析血統和發展史是有用的) 。

In the fullness of time , i fear that some ( but relatively few , i hope ) of my rendezvous points and their phylogenies will turn out to be wrong , in the light of new evidence 有時候,我真的擔心我的一些紀要點(我希望會盡可能地少)以及它們的發展史會被新的證據推翻。
