运用土壤颗粒质量分形模型计算松嫩平原低平地安达试区植被分布区和碱斑区样点土壤颗粒的分形维数，并建立分形维数与土壤颗粒不同粒级间的回归关系，以探讨土地碱化后土壤粒径分布的分形特征及其与土壤物理性状的关系。

The estimate model of the tree's volume is shown by allometry method,the CVD model that transforms tree's volume into biomass reduced and its practical model process is explained.

研究了用相对生长法表示的材积和蓄积模型，导出了单木材积与其生物量的关系模型以及区域蓄积量与生物量的关系模型，即CVD模型，并说明了实际的建模过程。

The results of experiments and analyses are as follows: under low density, there is no notable competition between individual plants, the function relation between height and biomass shows a "simple allometry"...

结果表明：植物在低密度条件下，个体间没有明显的竞争作用存在，株高与生物量之间表现为"简单的异速生长"关系，其异速生长表达式为 y =a + bx的形式；植物在高密度条件下，个体间存在着激烈的种内竞争，株高与生物量之间表现为"非线性的异速生长"关系，其异速生长表达式为 y =ax2 + bx + c的形式

State Key Laboratory of Millimeter Waves, Southeast University , Nanjing 210096, ChinaIn this paper, it is proven that the divergence relationship of electric-field and magnetic-field is non-zero even in charge-free regions, when the electric-field and magnetic-field are calculated with Alternating Direction Implicit Finite-Difference Time-Domain method, and the concrete expression of the divergence relationship is derived.

摘要该文证明了即使在无源区域，交替方向隐式时域有限差分法所给出的电磁场量不满足零散度关系，同时推导出了该散度关系的具体表达式。

Altho ug h The Great Charter has long been popularly regarded as the foundation of English liberties, it was a statement of the feudal and legal relationships between the Crown and the barons, a guarantee of the freedom of the Church and a limitation of the powers of the king.

尽管人们普遍认为《大宪章》为英国的自由奠定了基础，但该宪章只是规定国王和贵族之间封建关系和法律关系的文件，保证了教会的自由，限制了国王权利。

But regard the relationship between lamp and ambience,for example relationship with a cup of tea.

这个设计不去考虑台灯的造形，而是注意台灯和周围环境的关系，比如和一杯热茶的关系。

Results: aminopyrine in 20 ~ 200mg · L-1 concentration range of linear relationship, r = 0.9998, average recovery was 100.4%,Diantipyryl in 10 ~ 60mg · L-1 .the concentration range of linear relationship, r = 0.9997, the average recovery was 100.2%.

结果：氨基比林在20～200mg·L-1的浓度范围内呈线性关系，r=0.9998，平均回收率为100.4%；安替比林在10～60mg·L-1的浓度范围内呈线性关系，r=0.9997，平均回收率为100.2%。

Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
