具體包括以下幾個部分： 1 、針對雁形目鳥類異常復雜的分類狀況及分類上存在的爭議，根據雁形目鳥類的形態學、行為學、骨骼學、角蛋白、線粒體與核dna酶切片段長度多態、單拷貝核dna - dna雜交及線粒體基因dna序列分析等方面的研究，對雁形目鳥類分類中科、亞科和族的劃分及其相互間的系統發生關系進行綜述，分析系統學研究中存在的不足，提出了雁形目鳥類分類中急需解決的問題。Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts. among the adducts, o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties, which can eventually lead to chromosomal aberrations, point mutations, and cell death. this lesion also appears to be involved in tumor initiation, particularly in gastric carcinogenesis
單功能烷化劑n -甲基- n -硝基- n -亞硝基胍（ mnng ）是一種在環境中廣泛存在的化學誘變劑和致癌劑，它能和dna及蛋白質等生物大分子形成加合物（ adduct ） ，其引起的與突變有關的主要dna損傷類型是o ~ 6 -甲基鳥嘌呤，這種損傷與腫瘤尤其是胃癌的發生密切相關。The department of ecology and biodiversity of the university of hong kong has been appointed to carry out the 2001 - 02 programme. the main aspects of monitoring include sampling of marine benthic animals, analysing bird population data, habitat extent and conditions. cross reference will be made to environmental data such as mudflat sedimentation, water quality, sediment quality and land use changes
香港大學的生態學及生物多樣化學系，獲委派進行二零零一至零二年度的計劃，主要監測范圍包括抽樣調查海洋底棲動物、分析鳥類種群數據、生境分佈及狀況；亦會參考相關的環境數據，例如泥灘的沉積情況、水質、沉積物的質素、土地用途改變等，作為對照。Based on wang anyi s changhen ge, the multi - award winning novel that was voted the most influential work of the 90s in china, everlasting regret follows a legendary shanghai beauty from her glamorous days to her simpler life, as she struggles to preserve the dignity of her past while surviving the constant betrayal of her men
她從一個學生的身份開始蛻變，亮了一個相，摘下"上海小姐選美"第三名的桂冠。暗戀她的程先生知道，這位姑娘要展翼高飛了。王琦瑤這一飛，竟然鳥瞰了上海這座城市如何被時代洗刷的過程。The paleontologists believe juravenator ' s closest known relative may have been a fully feathered dinosaur from china, sinosauropterix. there are a number of possible explanations for juravenator ' s nakedness
這些古生物學家們相信，已知的與juravenator關系最為緊密的親屬可能要數中國的一種全身長有羽毛的恐龍中華龍鳥。It has a typical scaly dinosaurian skin, chiappe said. the paleontologists believe juravenators closest knownrelativemay have been a fully feathered dinosaur fromchina, sinosauropterix. there are a number of possible explanations forjuravenatorsnakedness
