Applying the techniques of real radical ideal, P-radical ideal , decomposition of semi-algebraic set in ( [72] ), affine Hilbert polynomial and B-net form of polynomials on simplex, this paper obtains two theorems of real C〓 piecewise algebraic variety dimensions and the real Nullstellensatz in C〓 spline ring.

4：应用多项式在单纯形上的B-网形式以及文献（[72]）中的实根理想，锥根理想，半代数簇分解定理，本文得出了实C〓分片代数簇的二个维数定理和C〓样条空间的实零点定理。

Lastly,we present an algorithm to isolate real roots of a univariate spline, i.e., computing asequence of disjoint intervals such that each of them contains exactly one real root of agiven spline function, which is primarily based on the use of Descartes\' rule of signs withits B-spline coefficients and de Casteljau algorithm of B?

最后，基于B-样条系数的Descartes符号准则和Bézier曲线的de Casteljau算法，我们给出了一元样条实根分离算法，也就是计算出一列不相交区间，使得每个区间恰好只包含此样条函数的一个实根。

As they approached the Piazza del Popolo, the crowd became more dense, and above the heads of the multitude two objects were visible: the obelisk, surmounted by a cross, which marks the centre of the square, and in front of the obelisk, at the point where the three streets, del Babuino, del Corso, and di Ripetta, meet, the two uprights of the scaffold, between which glittered the curved knife of the mandaia.

当他们接近波波罗广场的时候，人群愈来愈密了，在万头攒动的上空，可以看到两样东西，即方身尖顶的石塔，塔顶上有一个十字架，标明这是广场的中心和耸立在石塔前面，耸立在巴布诺街，高索街，立庇得街三条路的交叉口上的断头台的那两根直柱，在这两根直柱之间，悬挂着一把闪闪发光的弯刀。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

The aerobic bacteria andtotal microorganism were the highest in autumn and the lowest in winter;Theactinomycetes was the highest in spring and the lowest in winter;The rhizospherefungi was the highest in autumn and the lowest in winter, the non-rhizosphere fungi was the highest in spring and the lowest in winter.The average microorganism"s R/Sof four seasons in Eucalyptus grandis plantation is 1.40,the aerobic bacteria"s averageR/S of four seasons is 1.40,the actinomyeetes"s average R/S of four seasons is 1.40,thefungi"s average R/S of four seasons is 1.41.The uprightness distribution rule ofrhizosphere and non-rhizosphere soil microorganism in Eucalyptus grandis plantationwere the same,the trend is surface layer(0-20cm)＞middle layer(20-40cm)＞underlayer(40-60cm).Compared with the amount of microorganism in 2004, the amount ofmicroorganism in 2006 had a definite drop.

好气性细菌及微生物总数量秋季最高、冬季最低；放线菌数量春季最高、冬季最低；真菌数量根系土壤秋季最高、冬季最低，根外土壤春季最高、冬季最低；巨桉人工林三大类微生物四季的平均R／S值1.40，好气性细菌四个季度平均R／S值1.40，放线菌四个季度平均R／S值1.40，真菌四个季度平均R／S值1.41；巨桉人工林两样地根系与根外土壤微生物垂直分布规律一致，土壤微生物三大类及微生物总数量的垂直变化总的趋势是表层(0～20cm)＞中层(20～40cm)＞下层(40～60cm)；相比较2004年土壤微生物数量，2006年三大类数量及微生物总数均有一定程度的下降。

Habitat utilization of root vole was studied in the region of Haibei Alpine Meadow Ecosystem Research Station, the Chinese Academy of Sciences, from July to September of 2002 and 2003. Three indexes of activity intensities, runway length, runway branch number and burrow entrance number were used to estimate root vole's utilization intensities on four types of habitats, manual cultivated land, true meadow, swamp meadow and Dasiphora fruticosa shrub.

为研究根田鼠对不同类型栖息地的利用强度，于2002-2003年的7-9月在中国科学院海北高寒草甸生态系统定位站地区采用样方法测定了4种类型栖息地（人工耕作地、真草甸、沼泽化草甸、金露梅灌丛）中的3个根田鼠活动强度变量（跑道长度、跑道分叉数、洞口数）。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.

本研究在前期工作基础上，针对已发现的硫复铁矿富集区选择典型柱状样6根(深约1.5-2.5m，长柱样；B436、B437、B439、B459、B483、B484)，同时于扬子浅滩前缘新获取柱状样4根(深约0.3-0.5m，短柱样；ST9、ST13、ST15、ST23)，进行了U系测年，粒度分析、磁性测量、X—射线衍射分析、微体古生物鉴定分析、粘土矿物和化学元素含量测试，试图揭示东海外陆架浅部地层结构、揭露硫复铁矿在地层中的分布规律及成因机制，从而探讨该区晚更新世以来海平面波动模式及其控制下的地层发育。
