In this thesis, the present situation of heavy metals pollution and the physical and chemical properties of soils and the enrichment situation of heavy metals (Cd、 Hg、 Pb and Cr) in the vegetable body in the Harbin city greenbelt was investigated and evaluated. The results were showed as follows:The four heavy metals all polluted greenbelt soil by different degree in Harbin. The pollution of hydrargyrum is the most serious and reaches to the heavy pollution. The next pollution is plumbum, cadmium and chrome.

本文针对哈尔滨市区城市绿地重金属污染状况、土壤的理化性质，以及重金属(Cd、Hg、Pb和Cr)在植物叶片的富集情况进行了分析，并且对哈尔滨市区重金属污染状况进行了综合评价，结果表明：(1)哈尔滨市绿地土壤表层这四种重金属都有不同程度的污染，其中以汞的污染最为严重，达到了重污染；其次是铅和镉，铬的污染较小。

建立了用凝胶渗透色谱净化-液相色谱-串联质谱分析烟草中3种抑芽剂残留的方法。卷烟中的待测抑芽剂组分用V∶V=1∶1超声提取后通过凝胶渗透色谱净化；凝胶色谱柱为Biobeads S-X3玻璃柱(50 g，400 mm×25 mm)，流动相为V∶V=1∶1溶液，流速5 mL/min；收集第10~25 min流出的液体用液相色谱色谱-三重四极杆串联质谱仪测定。

Based on discussion of essentiality and some determinations of weights, we propose an ordered ratio method. Furthermore, using logarithm least square principle and group Analytic Hierarchy Process, we determine weights of imperil factors for radiant, and give a new judgment model and method of radiant imperilment grade evaluations.

第四章在分析目标权重的本质和概述几种常见的目标权重确定方法的基础上，提出确定目标权重的有序比值方法，并利用对数最小二乘原理和群体AHP方法确定载频、重频等威判诸因子的权重，给出一种判断辐射源威胁等级的定量与定性相结合的新方法。

The prohibition of the use of fleshmeat and milk at one meal: the hebdomadary symposium of incoordinately abstract, perfervidly concrete mercantile coexreligionist excompatriots: the circumcision of male infants: the supernatural character of Judaic scripture: the ineffability of the tetragrammaton: the sanctity of the sabbath.
