The distribution of the qualitative characters The performance of the 39 chief qualitative characters were observed and recorded,according to the test method of morphological characters in the .The results of distribution proportion of each character in cultivars group showed that the distribution of 32 characters(number of ray flower rings,floret curliness,shape of leaf base,size of stipule and so on) were very asymmetrical with near or above 70%cultivars concentrated upon one or two performance, however,the distribution of the other 7 characters(floret type,surface color of outer floret,back color of outer floret,color of disc floret,claw in base of sinus between lateral lobes,stem erectness and stem color) in the cultivars group were relatively symmetrical.

质量性状分布参照《菊花DUS测试指南》的形态性状测试方法,观察记录大菊39个主要质量性状的表现,计算各性状的表现式样在品种群内的分布比例,结果显示舌状花的重瓣性、花瓣曲反状况、叶片基部性状、托叶大小等32个性状的表现式样在品种群内分布极不均匀,接近或超过70%的品种集中在性状的1种或2种表现式样中;而花瓣形状、外花瓣表面色、外花瓣背面色、花中心部颜色、叶裂刻基部有无突起、茎的曲直性和茎色等7个性状的表现式样在品种群内的分布则相对均匀。4。

It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.

通过计算发现,盾构施工中盾壳摩擦和正面推力是盾构推力设置的主要因素,而刀盘与土体摩擦是刀盘扭矩设置的主要因素,盾构前方土体隆起主要由盾壳摩擦引起,刀盘摩擦作用主要引起地表沉降的非对称分布,地表沉降主要由盾尾空隙产生。

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.
