This paper presents an analysis method of mechanical behavior of aged concrete structures on elastic theory, and analyses the main causes of load bearing performance of concrete structures. the paper also illustrates some studies where structures exposed to the marine environment showed early deterioration and analyses the main causes of structural concrete deterioration, including concrete carbonization, corrosion mechanisms of concrete, and mechanisms of steel corrosion due to the penetration of chloride ions into the concrete. it shows that corrosion of the reinforcements is the main cause of structural concrete deterioration
本論文提出老化混凝土板的分層彈性理論，對混凝土結構的承載能力的影響進行分析；對浙江沿海混凝土結構及其構件的抗彎、抗剪、粘結性能以及結構的動力性能進行分析研究；提出了影響沿海混凝土結構耐久性的主要因素一混凝土的碳化作用，堿骨料反應，混凝土的腐蝕機理以及鋼筋混凝土中鋼筋銹蝕的影響因素。 -
After adding la3 + and ce3 +, the enhancement of relative membrane penetration ( rmp ) by heavy metal stress was reduced, the peroxidation of membrane lipids was alleviated and to some degree protected the membrane from injury by heavy metal ions, thus utimately promote the tolerance ability of plants to heavy metal stress. mesurement of element consentration by icp - ms method showed that rare earths could decrease the accumulation of heavy metal ions in the plants through competition effect
在受重金屬離子污染的培養液中施加la ~ （ 3 + ） ， ge ~ （ 3 + ）后，與單一重金屬毒害相比， la ~ （ 3 + ）和ce ~ （ 3 + ）有效抑制了重金屬脅迫引起的細胞膜透性增加，使膜脂過氧化水平減弱，從而延緩了對膜的損傷，最終增強了對重金屬離子的抗性。 -
In this paper, it was mainly studied that the penetration capacity and critical content of chloride ions in concrete with different water / binder ratio, fly ash and slag under immersion and cycle of dry and wet conditions
本文著重研究了全浸泡條件下和干濕循環條件下，氯離子在不同水膠比和不同摻量的粉煤灰、礦渣粉混凝土中的滲透性能，以及混凝土內鋼筋腐蝕的氯離子臨界濃度。
