The macrocyclic polyamines are a kind of excellent ligands and have a substantially high binding affinity with transition metal ions. Macrocyclic polyamine metal complexes as enzyme models are widely used in chemical biology, medicine and gene therapy. 1, 4, 7, 10-tetrazacyclododecane is a representative macrocyclic polyamines compound and shows high binding affinity with transition metal ions, such as Zn, Cu and Co. Their metal complexes especially multinuclear complexes were widely used in DNA, RNA recognition.

Three important conclusions are as follows:(1) the H2O content in garnet and omphacite can be up to 2000ppm and 3000ppm by weight respectively, indicating that they are significant carrier recycing surficial water into deep earth;(2) the heterogeneous distribution at the small scale of the H2O content and hydrogen isotopic ratios suggest that the whole subduction- exhumation process should be very fast;(3) the regular decrease of H2O content from rim to core within some garnet and omphacite grains indicates that hydrogen diffused out from mineral lattice during exhumation in response to sharp pressure decrease, and such hydrogen is expected to be involved in the early-stage retrograde metamorphism.

取得的主要科学认识包括：(1)石榴石和绿辉石的结构水含量可以分别高至2000ppm和3000ppm，这表明它们是板块俯冲过程中将地表水携带进地球深部的重要载体；(2)水含量和氢同位素组成表现出小尺度的不均一分布，说明板块的俯冲和折返过程是十分快速的；(3)在板块折返的早期，由于压力的降低，矿物中的H 会发生不同程度和尺度的扩散，这是早期退变质流体的重要来源。

The main pollutants from this chemical plant is perchloroethane, pentachloroethane, hexachlorobutadiene and HCB, and such pollutants are present in the soil with high densities, some as high as 1%- 95%, of which the perchloroethane is near the purity of the corresponding product, and especially this part of the soil contains comparatively high-density persistent organic pollutant HCB, which makes it suitable to be disposed of together with other soils. Therefore it is suggest that this part of soil should be separately dug out and transported outside of the site.

化工厂的主要污染物质是六氯乙烷、五氯乙烷、六氯丁二烯和六氯苯，土壤中上述污染物的浓度非常高，有些达到1%至95%，其中六氯乙烷接近相应的产品的纯度，特别是这一部分含有较高浓度的持久性有机污染物六氯苯，不利于与其它土壤混合处理，建议将这一部分单独开挖出来并运出场外。
