通过改进的连续浸提试验，将高铅茶园土壤及常态茶园土壤中铅的存在形态可分成6种形态：水溶态、可交换态、碳酸盐结合态、铁锰氧化物结合态、有机物结合态和残渣态，并用 ICP-OES 法检测了各种形态铅含量及总铅含量。

Then quality upgrading scheme was explored in order to solve the high content of sulphur and nitrogen in pyrolytic oil, low flash point as well. Yields of pyrolysis of scrap tires in a pilot-scale rotary kiln under 550℃were firstly summarized. Then elemental composition and physiochemical properties were analyzed on both pyrolytic crude oil and its fractions. Based on these researches, the feasibility that pyrolytic oil is used as fuel was discussed. From FT-IR spectra the functional group compounds were generally acquainted, and by column chromatography analysis chemical compositions were clearly known. Then through GC analysis the absolute content of BTX in pyrolytic crude oil was defined.

本文首先考察了中试回转窑550℃下的废轮胎热解产率及热解原油的元素组成和理化特性，对其作为燃料使用的可行性进行了分析；通过实沸点蒸馏研究了轻质、中质馏分热解油的基本特性：红外分析得出了有代表性馏分热解油的大致官能团组成形式，对热解油的强芳香性和部分不饱和性有了整体了解；化学族组成分析进一步了解了热解油内在化学族组成和含量，对热解油的内在性质有了更为深入理解；气相色谱分析对热解油中富含的苯、甲苯和二甲苯进行绝对定量，为热解油提取BTX化工原料的经济性提供了参考。

By using simulation-analysis software CFD,STAR-CD,a three-dimensional simulation analysis was conducted of the semi-volute suction chamber of a gas-oil multiphase pump for flow fields at different void fractions.

利用CFD模拟分析软件———STAR-CD，对油气混输泵半螺旋形吸入室在不同含气率下的流场进行了三维模拟分析。
