There is an independent stand-alone mode, there is also the work of multi-cluster model.

有独立单机工作模式，也有集群多机工作模式。

And more and more scholars and statesmen put forward to developing the local economy by clusters.

而且越来越多的学者和政策制定者也提出通过产业集群来发展本地的经济。

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.

综合以上的研究结果表明：(1)北京地区现有大量大菊品种，且花型与花色较为丰富；(2)珍稀花型、花色品种亟需保护；(3)大部分数量性状是符合正态分布的，少数重点观赏性状迫于选择压力呈现偏态分布，概率分级法能够辅助大菊的数量性状建立新的分级标准；(4)大部分质量性状在品种群内的分布是不均匀的，可能是由菊花性状遗传分化的不均衡性或受到选育重点性状的连锁作用而造成的；(5)大菊花部性状相对稳定，对品种分类影响较大，其托叶部分也具有一定程度的稳定性，可以作为品种分类的合理补充，而叶部性状稳定性较差，在品种分类中应作为更次一级的分类依据；(6)平瓣类、管瓣类和匙瓣类的亲缘关系最近，畸瓣类品种花瓣先端特化受到人们的喜爱，长期的选择压力使其区别于3种基本瓣型，而这四种瓣型与桂瓣类在亲缘关系上较远；(7)ISSR分子标记检测表明：大菊品种多态性位点百分率较高，平瓣类品种的遗传分化最为丰富。

Because there are a complex terrain and various climates in the Rocky Mountain region, taxa of the matsutake group and of the stirp Subannulate differentiated greatly and many new species have come into being there. For the effects of hosts on their speciation, it needs further investigation.

这些种明显只见于北美西海岸，由于北美西海岸多山地，地形复杂，松口蘑群和亚环族的种类在那儿均发生强烈分化，因此出现很多新种，该处植物分化和菌根菌物的关系需要进一步研究后得出。

Conversation would ricochet from Russia's recent economic history to the tragedy of the aborted reforms brought in by his hero, Pyotr Stolypin, one of Tsar Nicholas II's prime ministers.

费奥多罗夫谈话总是天马行空，这一刻还在讨论俄罗斯的全新经济史，下一刻就跳到他的偶像斯托雷平功亏一篑的改革上去了；有时候他会大谈普京意欲规范俄国大公司的企业行为，最后却落得个一败涂地的结局，突然间又把矛头指向西方银行家，指责这群伪君子偷税漏税。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!

天啊，这是第二次你打败了我！
