Result shown: value of fractal dimension is a comprehensive index, which reflect the changes of landscape, patch areas, patch numbers, area per patch, and their interaction. And the index can reflect the irregular degree and the complex degree of landscape patch in dumping place. The fractal dimension of mixed vegetation of arbors – shrubs and mixed vegetation of shrubs maintain the high level, while fractal dimension of new reclamation land and grass land are low. The difference of other type landscape fractal dimension is not significant. Vegetation landscape is influenced by many kinds of factors. It is primarily influenced by surface material composition and terrain in south and west dumping place, which diversity index is high. It is primarily influenced by vegetation type in inner dumping place and expanded west dumping place. The landscape multiplicity index of the mixed vegetation of grass and shrubs is higher than other landscape type, but landscape dominance index of this area maintains on the lower level.
结果表明:分维数的大小反映了景观斑块面积、斑块数量和平均斑块面积等因素的相互作用,反映了排土场内景观斑块的不规则程度和复杂程度;乔灌混交地和灌木混交地保持着较高的分维数,新造复垦地和草地的分维数较低,其它景观类型的分维数则差别不大;植被景观受多种因子的影响,在南排土场、西排土场受地表物质组成和地形的影响为主,其多样性指数较高,在内排土场、西排扩大区受植被类型的影响为主;草灌混交地的景观多样性远高于其它现有的复垦植被区,但其景观优势度则保持在较低水平上。

A2, in the world, the vast majority of AM points per inch of the number of lines in the dot-matrix, only Germany once in a while the number of dots per centimeter line. 150 line represents the inch 150 x 150 line = 22,500 a number of points, higher numbers, the more business card printing and membership card, the more difficult, making the good paper business card printing and membership card making for behaving as a musician of image quality, the use of more than 300 line number would be closer to the continuous tone of the feeling, on the other hand, are coarse thick wire.
A2、在寰宇上,绝不小众数的AM网不面都以每寸有众少线的不面阵来算,只有德国不常以每公分有众少线筹算。150线表示每寸有150×150线=22,500个网不面,数字越不小不面数越众,制卡和会员卡制作越艰难,在好的纸张制卡和会员卡制作后提下可表示很澈底的影像品格,搁置300线以上的线数不离很挨近不断调的发觉,反之,粗纸不离给用粗网线数。

Experimental results indicate that the B/A value greatly affects the internal Nusselt number and friction factor of the twisted tube because the parameters decrease with the increase of B/A and S/d values, more rapidly with the former, and that the Nusselt number and friction factor of the twisted oblate tube increase respectively by 30%~150% and 20%~50%, as compared with those of the smooth tube at the same Reynolds number and Prandtl number.
实验结果表明:高扭曲比螺旋扁管的管内努塞尔数和阻力系数均随B/A值和S/d值的增大而减小,但随B/A值的增加而减小得更快,B/A值对高扭曲比螺旋扁管的管内传热与流阻性能影响更大;在相同雷诺数和普朗特数下,高扭曲比螺旋扁管管内的努塞尔数为光滑管的1.3~2.5倍;阻力系数为光滑管的1.2~1.5倍。

Results showed that the overland flow pattern has close relationship with the grass cover and water inflow rate, it changed from the laminar and tranquil flow to the transition flow and tranquil flow for the grass-covered sloping segment with increasing water inflow rate, but it was almost transition flow and tranquil or rapid flow for the sloping segment without grass cover.
结果表明,坡面流流态与放水流量和草被覆盖关系密切,随流量的增大草被覆盖断面坡面流流态由层流-缓流转变为过渡流-缓流,而无草覆盖断面的流态几乎都处于过渡流-缓流或急流状态;沟坡径流大都属于过渡流-急流状态,试验过程中,草被覆盖断面的径流雷诺数和弗汝德数变化很小,无草被覆盖断面径流的雷诺数呈逐渐增加趋势,而弗汝德数呈逐渐减小的变化趋势。

As for the study of isospin in intermediate energy HICs, we've investigated how bothstength and density dependence of symmetry potential affect many measurableobservables, such as the yield, phase-space, and isospin distributions of fragments, as wellas the correlations between Intermediate-Mass-Fragment multiplicity 〓 andCharged-Particle multiplicity 〓 Light-Charged-Particle multiplicity 〓 andNeutron multiplicity 〓. The aim is to find sensitive observables specifically for strengthand density dependence of SP.

In another way, the technology of FQ-PCR (real-time fluorescent quantitative PCR) was used to measure the ratio of white nucleus occupying the whole nucleus in 34 light-yellow strains. Among them, the ratio of yellow nucleus and white nucleus in 19 strains was access to 1:1, while the other strains showed that the copies of yellow nucleus exceeded white ones.
