I . a mtil ( iaxial elastic - plastic hardening - sofling constitutive model of concrete is proposed iii order to offer a nonlinear material model of concrete for space restoring force analysis of reinforced concrete members taking into account the softening behavior of concrete . the concrete material model is incorporated the elastic - plastic hardening fracturing constitutive model of concrete with the plastic - fracturing theory of concrete , modified without defining two loading functiomis , and based on five parameter power function failure criterion proposed by guo zheng - hai etc from tsingliua ( jniversity , or three parameter unified strength theory proposed by yu mao - hong from x ian iiaotong university 1 、将砼弹塑性硬化断裂本构模型与塑性断裂理论结合起来，并加以改进，但无需定义两个加载面，以清华大学过镇海建议的五参数幂函数或以西安交通大学俞茂宏建议的，参数统一强度理论作为砼的强度破坏准则，建立了砼多轴弹塑性硬化松驰本构模型，能为钢筋砼构件空间恢复力分析提供砼非线性材料模型，并能反映砼材料的软化段。
The last chapter is the summarize of the whole paper and give some advice to the project . the research of port handling system is now generally focus on general cargo and bulk cargo . the scarce of the chemical handling ports , small scale , lower management and technology , complex special chemical knowledge make the researches and references in this facet scarcely , as the largest scale of chemical handling area in china , the research of zhenhai chemical handling district is advanced and representative 目前国内对于港口装卸工艺及其布局的研究主要集中在件杂货和干散货的装卸工艺布局的研究上，由于国内从事液化品装卸的港口还不是很多，大部分规模较小且技术上和管理上较为落后，且研究的专业性很强，因此对液体化工装卸工艺的研究及相关的参考文献很少，同时由于宁波港镇海液体化工作业区是目前国内最大的液化品中转基地，因此本文的研究具有一定的前沿性和参考价值。
We selected three kinds of home - made heavy traffic asphalt - zhonghai , maoming & zhenhai with two kinds of import name brand asphalt shell and esso , tested their quality with our heavy traffic asphalt technical standard . research further carried out bituminous mixtures testing of ability with zhonghai ah - 70 and esso asphalt 课题研究选择了中海、茂名和镇海三种国产重交通道路沥青以及shell和esso两种进口沥青，按照我国重交通道路石油沥青的技术标准进行了分析比较。
The products have applied to the trades extensively , such as : petroleum , chemical industry , metallurgy , environmental protection , light industry , medicine , national defence , shipping , spaceflight , hydro power station operate and patrol examine , hydraulic pressure , air pressure system etc . the products ahd been sold to many countres , yangzi petrochemical industry and zhenhai refining internal large - scal enterprises also use products from the company 企业产品已广泛应用于石油化工冶金环保轻工医药国防船舶航天电站运行巡检液压空压系统等行业。产品已行销多个国家和地区,扬子石化镇海炼化等国家大型企业也在应用本企业产品。
The article is just base on the above background to do some researches about the liquid chemical loading and discharging system of zhenhai district , try to use some system analyze tools , combining the situation today and future will be , to find out a suit of layout project of the liquid chemical handling system which fit the need of the future 本篇论文正是基于以上的背景对宁波港镇海液体化工区的液化装卸工艺布局进行研究，试图通过借助一定的分析工具，结合化工区发展的现状和未来的规划，寻求一套能满足化工区今后发展需要的整体工艺布局方案。

The results show that the location sound speeds for the tank above has been confirmed as 1 . 2 1 . 4m / ms and 3 . 2m / ms and the degree of the superposition of two lucy value and sound speed curves correlated directly with the pertinence of the signal . ( 4 ) . introducing the flux leakage examination and the comparison made between magnetic flux leakage examination and ultrasonic testing proved that magnetic flux leakage examination can be used 分析国内不同地区(镇海、日照、厦门) 、 12个服役9 - 19年的常压储罐漏磁检测的结果,统计所存在缺陷的腐蚀程度及分布情况,从而确定声发射检测的重点部位在储罐的中间部位。
