Even in France, where the existence of so many varieties of delicious wine had hitherto imposed a judicious connoisseurship and has led to the branding of mere drinking as a brutish solecism,(而把喝烈酒視為粗野的行為)even in France ,the American booze-snobbery, with its odious accompaniments a taste for hard drinks in general and for cocktails in particular is making headway among the rich.
即使在法国,由于有这样多不同种类的葡萄美酒,一直使品酒时极有鉴赏力,而把喝烈酒视为粗野的失礼行为;即使在法国,美国的狂饮势利感及其伴随而来的可憎的爱好——通常喜欢喝烈酒,特别是爱喝鸡尾酒——在有钱人中大有进展。

Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.
本研究的主要研究结果如下:1、北京市具有典型的城市景观特征,林地用地的面积占市域面积的42.534%,为基质景观斑块类型,旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类;从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出,斑块形状简单,主要景观斑块种类的景观分维度指数值均不足1.1,表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面:(1)在研究时段内,北京市景观斑块种类变化不大,景观组分面积和斑块数变化明显,其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势,增加幅度为北京市总面积的7.66%,农业用地与林地的面积虽呈波动变化但总体呈减少趋势;景观斑块数量先增后降,总体呈下降趋势,其中耕地与林地斑块数的变化最为明显。

Results indicate that the stigmatic surface morphology of Pedicularis species is related to the type of corolla structure occurring in the species. Pollination studies in 8 Pedicularis species demonstrated adaptation between stigmatic surface morphology and other aspects of floral biology.
拥有更膨大,更粗糙的柱头表面特征的植物种类通常都是具喙或长管种类,而短管无齿种类的柱头平滑且无膨大,相反,对于长管具喙种类而言,柱头在膨大的同时,更形成了发达的"沟回"结构,这种柱头结构式样的不同直观、显著的改变了不同种类的传粉效率。

Tricholoma may be a paraphyletic genus two. The collections identified as T. caligatum is a mixture. Some parts of them from France are members of T. matsutake, the other parts from North America are closed to T. bakamatsutake and T. fulvocastaneum. Tricholoma robustum and T. focale form a clade which is obviously a sister group of the stirp Subannulate. The stirp Caligata was defined as a group mainly on the basis of the predominant veil. But from the result of molecular systematic analysis, the presence of veil is not a stable character in the matsutake group. Species having symbiosis with conifers and broad leaf tree are all transformed from those whose host specificity is not strict. The phylogenetic tree based on ITS sequences resembled the tree of NJ algorithm based on cladistic coding. In the phylogenetic tree based on morphylogical characters, T. zangii and T. bakamatsutake form a clade, but it is the result of convergent evolution as suggested by molecular analyses. The distribution area of the matsutake group can be divided into six regions: middle and northern Europe region, Mediterranean region, Hengduan Mount.— Southeastern Tibet region, Northeastern China—Japan—Far-east Russia region, the Atlantic—North America region and the Rocky Mountain region. The abundance center of the matsutake group are Hengduan Mount.—Southeastern Tibet region and the Rocky Mountain region. Hengduan Mount.
松口蘑群的分子系统学研究得出的结果有:由于粗壮口蘑和羽衣口蘑明显和亚环族(Tricholoma,section subannulate)的种类是来自同一个谱系,和其它松口蘑群的种不具有最近共同祖先,因此松口蘑群是一个多系群;松口蘑群和口蘑属其他种类的亲缘关系比和蜜环菌属更接近;梭柄松苞菇和松口蘑群的差距明显小于油黄口蘑(T.flavovirens)和棕灰口蘑;口蘑属是一个多系群;鉴定为欧洲口蘑的标本明显不是一个单系群,其中一部分是松口蘑,另一部分和黄褐口蘑及傻松口蘑(T.bakamatsutake)比较接近;划分松口蘑群的标准是菌环的存在,但从分子系统学的结果来看,菌环的存在与否并非是一个很稳定的性状;和针叶树专性共生及和阔叶树专性共生均由寄主专化性不强的种类转化而来;在形态学系统发育树上青冈口蘑和傻松口蘑被聚为一个分枝,分子系统学的研究结果表明,这是趋同进化的结果;用支序方法编码作出的NJ树的结果更接近ITS序列的结果。

When the frequency of codon usage of citrus was compared to Homo sapiens, Drosophila melanogaster, Saccharomyces cerevisiac and Escherichia coli, we found that the codon preference is considerably different between citrus and non-plant species. While compared to Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Musa acuminata, we found that the codon preference was identical in dicotyledons, but was different between citrus and monocotyledon, Oryza sativa and Musa acuminate.
