Third, The author analyzed the shimming method of the existing magnet system and programmed it. Because the base field homogeneity of the open magnet is worse and only passive shimming is available, it is necessary to study more effective shimming algorithm. The ordinary shimming method is based on the disintegration of the magnetic field using spherical harmonics. It is so tedious that involved in large scaled non-linear equations.

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。

The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.

研究结果表明:现代黄河三角洲在以宁海为顶点的河口扇形区域,近期均经历了不同程度的地表下沉过程,但是随区域地理位置和时间的不同,地表变化空间差异性比较明显;三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小,后期甚至出现轻微的抬升;滨海沿岸附近地区的地表形变特征相对比较复杂,各期叶瓣相互叠置及其各类沉积物的不均匀分配,使由沉积物自然固结压实引起的地表形变具有显著的空间差异;目前,除清水沟流路叶瓣表现为快速沉降以外,其它滨海沿岸区基本上都表现为微弱的下沉。

通过数值分析,模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场,结果表明:研究区主应力方向为北东~南西向,第二期的构造扭动使其由北向东发生了一定的偏转,但总的方位变化不大;O〓~S~D时期,塔中地区构造运动较强,研究区大部分处于高应力状态,岩石破裂程度较高,而岩芯观察结果也证实了这一结果,即O〓灰岩地层中早期形成的构造结构面比较发育,单个结构面的规模也较大;C~P时期,岩石的破坏程度较早期有所提高,主要表现在两个方面,一是各局部区岩石的破坏程度普遍有所提高;二是各个级别破裂区的分布范围相应地扩大了;研究区应力分布表现出明显的不均匀性,特别是剪应力,无论是O〓~S~D时期,还是C~P时期,都有很大的差异性,特别是在小断层的端部,剪应力比较集中,而且在断层的两盘,剪应力方向和大小都变化极快。
