中文摘要：
通过在草甸土、红壤和荒漠土中进行碳钢、铝、铜、铅试件自然埋藏研究,比较了金属在不同土壤中的不同腐蚀特性、规律及腐蚀原因.结果表明：草甸土中的碳钢、红壤中的铅及荒漠土中的铜腐蚀较重.草甸土高含水量及低电阻率,红壤pH值及NO_3~-,荒漠土Cl~-和SO_4~（2-）及质地不均对不同金属造成腐蚀,三种土壤微生物的活动都促进了金属的腐蚀.
英文摘要：
By means of naturally burying specimens of carbon steel,Al and Pb in soils of meadow soil,red soil and desert soil respectively,corrosion characters and corrosion regulations of the metallic materials and the relevant causes were studied.The results indicated that carbon steel in meadow soil,Pb in red soil and Cu in desert soil were corroded rather severely.High content of water and low resistance of meadow soil,pH of red soil,NO_3~- in red soil,Cl~- and SO_4~（2-） in desert soil and the non uniform in soil quality might be the main factors for the corrosion of the metallic materials.Furthermore,microbes in three kinds of soil could accelerate the corrosion of metallic materials.
