Sum up under the same condition, NT has more advantages than CT onthose indexes of hydrolyzable nitrogen ,available phosphorus and potassiumin 0-20cm soil layer while there are no evidently difference underneath 20cmsoil layer.2.2 In NT fertilization zone and mantle zone, contents of organic matter in0-40cm soil layer are higher than that in CT.

和常规处理相比，免耕施肥区处理 N3T和覆盖区处理 N3TC 在 0-20cm 土层显著提高了有机质含量，其中覆盖区增加效果显著。2.3 和常规耕翻处理相比，成熟后免耕处理在 0-20cm 土层土壤显著降低了土壤容重和增加了毛管孔隙度和非毛管孔隙度，显著提高了土壤总孔隙度。3 免耕对土壤中不同形态氮素以及土壤水分含量变化的影响3.1 土壤铵态氮拔节期至成熟期是免耕处理和常规处理铵态氮显著差异的形成时期。

Its give the ancients not tire of irritatedly each stars that they can see with naked eye had a name, these name itself were full of a suggestion, while starlight enclothes the earth, astral life covered a multitude.

After covering, the gravity centers of covers are recalculated to achieve better effect. The iterativeness of samples is not needed. Therefore, the problems, such as the choice of initial sample and the clustering speed, are solved, which can not be solved with other algorithms.

该算法可以在覆盖后求重心，不断调整所做的覆盖，对大量的样本数据不需要迭代，因而解决了其他聚类算法难以解决的问题：初值的选择和聚类速度。

格陵兰冰原将全岛覆盖，仅在狭窄的边缘有少量岩石露出。因为动、植物贫乏，故有人将格陵兰的冰原称为&冷荒漠&。南极洲冰原不但将全陆地覆盖，而且有些地方扩大至海上。冰原的厚度有些地方可达数千米。

And (20. 5 ± 1.7) ml· 100 g-1 ·min-1, respectively. When compared in 3 groups, the temporal and parietal lobe rCBF had a decreasing tendency in aMCI group, while in VCI-ND group, the most dominant decreasing parts were mainly concentrated in white matter region (17. 7±2. 3 ml·100 g-1·min-1, F = 5. 740, P = 0. 002. Whatever the depth or the width was, beth periventricular and subeortical deep white matter, anterior and posterior ventricular regions were all involved. There are no dominant difference of rCBF in caudate nucleus, lentiform nucleus and thalamus.

2NC组、aMCI组和VCI-ND组患者的rCBF表现比较：aMCI组颞、顶、枕叶的rCBF值呈一定趋势的减少，VCI-ND组额叶的rCBF值呈一定趋势的减少，而VCI-ND组rCBF下降最明显的部位集中在白质区域[(17.7±2.3)ml·100 g-1·min-1，F=5.740，P=0.002]，从深度看覆盖了脑室旁白质和皮质下深部白质两部分，从长度看覆盖了白质的前后区域。3组基底节区核团包括尾状核、豆状核和丘脑的rCBF值比较差异无统计学意义。

Provincial SAI-TVs have had powerful extended value in theory and hold many advantages for regional and countrywide market. But Provincial SAI-TVs show very strong department property according to administrative partition, its regional restriction of the scope of operations make the localness more strong than other places.

省级卫视借助卫星技术实现了本省强势覆盖和外省部分覆盖，理论上已经具备强大的衍生价值，可以主打具有优势权的本省市场，还可以兼顾区域或全国市场。

The absorption capacity of heavy metals in vegetated wetlands with reed, Suaeda glauca and Spartina alterniflora was higher than that in non-vegetated wetlands with high density of macrobenthos, especially Bullacta exarata and Mactra veneriformis Reeve.

There is a significant difference in daily change of soil moisture content at depth of 5 cm between the areas with and without microbiotic crusts.

结皮覆盖区与无结皮覆盖区土壤水分的日变化特征明显不同于距地表5cm处，而其他各土层的变化趋势则较为一致。

Three hypotheses is put forward, based on microexamination about sample evaporation during determaination of isotope abundance by thermal ionization:1. Only atoms uncovered by outer layer atoms can be vapoured; 2. Atoms covered by outer layer atoms can diffuse but cannot vapoure; 3. The probability of diffusion of isotope atoms is in direct proportion to its probability of evaporation.

根据对热表面电离源同位素丰度测量过程中样品蒸发的微观研究，提出如下三条假设：(1 )未被外层原子覆盖的原子才能蒸发；(2 )被外层原子覆盖的原子只能扩散不能蒸发；(3 )同位素原子的扩散几率与蒸发几率成正比。
