Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Permo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ34S values of the ores commonly fall within the accepted mantle range of 0 ± 2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ34S value is also within this range.

如1.1 Ga的Duluth杂岩、Noril'sk地区二叠-三叠纪侵入岩和1.4 Ga的Kabanga侵入岩体中矿床的硫同位素测定结果证明硫来自含硫化物和硫酸盐的围岩。1.3 Ga的Voisbey's Bay矿床矿石的硫同位素δ34S值通常落入公认的地幔硫同位素组成范围(0±2‰)内，而对其元古宙变质沉积围岩进行的详细研究结果显示δ34S的平均值也在此范围。

While for some indexes,such as length of medial longitudinal arch,length of lateral longitudinal arch,height of first metatarsophalangeal articulations,there is no longer changing with increasing load after adapting to a relatively lighter load.There is marked difference on the foot shapes between different items youth track man,especially for the throwers.Finally,five dimensions of foot morphological characteristics were found to establish the foot-shape-index-system,which are respectively metatarsophalangeal index,heel index,ankle index,arch of foot index and length of foot index,including 15 items.

更多载荷变化的影响；我国青年田径运动员的内侧纵弓长、外侧纵弓长、第一跖趾高、足背高、拇趾偏角、足跟面积等指标在一定载荷范围内变化明显，但超过承重范围则不再因载荷增大而变化；不同专项的青年田径运动员的足部外形指标间存在明显差异，以投掷项目运动员的差异最为突出；足长度指标、跖趾部指标、足弓部指标、足跟部指标、足踝部指标共15项内容为代表我国青年田径运动员足部外形特征的指标体系。

These suggest that the xenocrysts were captured by the enclave magma from the host magma. On diagram of total alkali vs. SiO〓(Middlemost, 1994), most samples of the host rocks plot within the area of diorite, the samples of the quenched margin plot within the area of gabbro-diorite and the samples of the enclave plot within the area of diorite.

在Middlemost(1944)提出的侵入岩全碱-SiO〓分类图解中，寄主岩的投影点落在花岗闪长岩范围内，淬冷边的投影点落在辉长闪长岩范围内，而包体的投影点大都落在闪长岩区。

Originally limited to dialkylamino methylenation, the application of Mannich reaction has been expanded much further in recent years to a wide variety of monosubstituted amines, amine equivalents and amides. In addition, a variety of Aza-Mannich and Mannich-Michael methodologies have emerged.

最初该反应的应用范围仅局限于二烷基胺亚甲基化反应，近年来才得到了长足的发展，其研究范围扩展到单取代的胺、胺的类似物以及酰胺等化合物，并发展形成Aza-Mannich和Mannich-Michael等复合Mannich反应。

Beijing environmental problems hold severe, and atmospheric and water pollute, soil and water loss, hot island and yawp are leading problems,and take on territorial characteristic. Based on research on relativity between urban forest and these environmental problems, urban forest can effective improve environmental quality in Beijing. And for the aim of improve environmental quality, Beijing forest overlay should attain 35% at least in citywide range, and local-areas being severe environmental problem should be provided with higher forest overlay.5. Through the study on urban forest needed capacity, Beijing's forest coverage is up to par in citywide range, but montanic forest coverage, plain covered with trees and average forest area are lacking, and CO2 and O2 balance is incapable;form the point of heat and balance CO2 and O2 balance,urban forest the city zone and suburb is lack. There is urban forest developmental potential space,but the city zone and suburb area need be compensated form urban forest in circumjacent region.6. On the based of the above results and ecological network system, the author drived whole region into city area, plain and mountain area are needed at the point of planning thoughts of running-through forests and water .

根据城市森林与北京市主要环境问题的相关性分析，城市森林在改善这些环境问题中具有重要的作用，为有效改善这些环境问题，整个北京市域范围内森林覆盖率至少达到35%，并且分布比较均匀，环境问题严重的局部区域需要不同程度增加森林覆盖率。5、通过对北京市城市森林需求量研究发现，虽然在市域范围内北京森林覆盖率达到了国家标准，但是山区森林覆盖率、平原林木覆盖率、城区人均森林面积不足；从区域热平衡和碳氧平衡角度分析，城区和郊区不能满足本区域的城市森林需求量，虽然北京市城市森林具有一定的发展潜力，整体上基本可以满足城市需要，但是这些区域需要依靠周边区域城市森林的补偿。6、根据以上的研究结果，以中国森林生态网络体系建设的点、线、面布局理念为指导，以&林网化——水网化&作为优化理念，将北京市整个市域划分为城区近郊区及其辐射区域，平原区和山区三大区域，依据三大区域特点进行城市森林布局优化。

General analysis indicates that Myriophyllum spicatum L.Panicle shape of the absorption of chromium Cr6 + concentration and treatment exist between the concentration of significant positive correlation with Myriophyllum spicatum L.can pollute the environment in better enrichment of chromium, the background environment The higher concentration levels of heavy metals, plant accumulation of heavy metals in higher concentration levels, the application of plant technology for the repair of heavy metal pollution on the environment to provide a scientific basis on Myriophyllum spicatum L. of heavy metal pollution of wetland restoration has great potential.

综合分析表明，在一定范围内，穗状狐尾藻对铬Cr6+的吸收富集含量随处理浓度升高而增大，说明穗状狐尾藻在污染环境中能较好地富集重金属铬，从而得出在一定范围内，环境背景中重金属含量水平越高植物富集重金属的含量水平也越高的结论，这就为应用植物技术修复重金属对环境造成的污染提供科学依据，而穗状狐尾藻对湿地重金属污染具有较大的修复潜力。
