退化机理 meaning in Chinese
degradation mechanism
Examples
- On the basis of experiments of breakdown and reliability of pcss , the mechanism of carriers propagating is deeply studied , and the breakdown characteristics and degeneration mechanism are analyzed in the theory
通过对非线性pcss ’ s载流子输运机制的深入研究，结合开关的击穿和寿命实验，对pcss ’ s击穿机制及性能退化机理在理论上作了分析。 - In this paper , by the accelerated corrosion methods of man - made climate and galvanostatic to corrode the bars , experiments were carried out to study the different structure behavior of corroded reinforced concrete beams , and it was learned that the condition of man - made climate was closer to practice than galvanostatic method
摘要通过采用人工气候和通电快速锈蚀模拟方法，对锈蚀钢筋混凝土梁进行试验，以对比研究结构性能退化机理，结果发现锈蚀后钢筋混凝土梁的强度、延性和破坏形态发生了急剧变化，而且人工气候环境下的混凝土内钢筋锈蚀比通电条件能更好的贴近实际情况。 - The research of soil degradation in pur country is mainly concentrated on the red earth hilly area in the south in the past , and is less on the loess plateau that is one of the most fragile areas . based on field experiment and laboratory analysis , discuses the degradation mechanism , and raises the methods of refreshing and reestablishing land productivity of huangshan soil in chunhua county of shaanxi . in the hope of serving development of western regions and ecological environment construction that concede the land to forestry ( the grass )
我国以前对土壤退化问题的研究主要集中于南方红壤丘陵区，对生态环境最脆弱的黄土高原地区的土壤退化研究相对较少，故本文以黄土高原地区陕西淳化县的侵蚀性黄?土为对象，通过野外人工模拟降雨试验和室内分析相结合的方法，探讨了侵蚀性黄?土的退化机理，提出了恢复和重建黄?土土地生产力的途径和方法，以期服务于西部大开发和退耕还林(草)的生态环境建设。 - Deterioration mechanism of the bond property between rusty rebar and corroded concrete was discussed . because that the bond strength between the corroded rebar and concrete is affected by many factors , and the relation between the factors and bond strength are highly nonlinear , to build the any calculation model will be very difficult . bp nn model was built up herein to predict the ultimate bond strength between the rebar and corroded concrete , good results are achieved
阐明了锈蚀钢筋与混凝土之间粘结性能的退化机理；鉴于锈蚀钢筋混凝土之间的粘结性能受到多因素影响，且影响因素集与极限粘结强度之间存在着复杂非线性关系，建立了bp神经网络模型预测锈蚀钢筋与混凝土之间极限粘结力，取得了较好的预测效果。
