The environmental quality problems of construction engineering are endangering the existence and sustainable development of human beings, so their treatment is becoming common understanding of all levels of governments and the public. In this paper, the forming course and affecting factors of environmental quality and main symptoms of its problems are analyzed from the definition of environmental quality in construction engineering. Then, the essence of the problem is revealed, that is comprehensive abilities for quality activities and their results can't meet the regulated requirements. Finally, it expounds five basic characteristics of the problems to enhance people's understanding.  相似文献

The main structure in construction engineering is the organic part of the load - carrying system of construction engineering. Its quality is the core for realizing the value of construction engineering quality. The essence of its quality problems is that the quality behavior, intermediate output or final product of the construction body cant meet the requirements of national laws, regulations and obligatory criteria during construction work. Its quality problems have the following eight traits such as complexity, frequent occurrence, potentiality, chain effect, heavy damages, multiple responsibilities, difficulties of treatment and high expenditure for treatment.  相似文献

Based on the fundamental principles of science of complexity, the complexity of clusters of engineering projects is analyzed in the light of integrity, dynamics, gradation, openness and autonomy. It is believed that the quality supervision of clusters of engineering projects is a typical complex composed of several essential factors, between which there exists a complicated nonlinear relationship. The behaviors and manners of quality supervision are proposed including management evaluation, tree - shape quality supervision, model leading system, independent third - party assessment with a view to strengthen and enhance the quality supervision of clusters of engineering projects.  相似文献

For most evaluating methods of engineering rock mass, the integrality index is an important assessment factor. However, sometimes the value of integrality index would be more than 1.0 because of unloading effect of rock samples and differentia of frequency between the measurements of rock samples and rock mass. In order to solve this problem, unloading index and frequency correcting coefficient were put forward to revise the integrality index. Moreover, the BQ evaluating method proposed in the national standard (GB 50218-94) was improved with the revised method. With the case study of the project of water sealed underground oil tank in Huangdao, it was found that the quality of rock mass in the site was grade I or II.  相似文献

基因工程改良作物种子蛋白营养品质的策略及其研究进展   总被引:1,自引:0,他引:1  
作物种子蛋白是人类和牲畜日常蛋白质的主要来源;与肉类相比,植物蛋白质的营养品质往往不够完全,主要表现在禾谷类作物种子蛋白质中的赖氨酸和色氨酸含量低,而豆类和蔬菜类蛋白质缺乏蛋氨酸和半胱氨基酸等含硫氨基酸.采用传统育种技术提高作物蛋白质营养品质方面的成效不大,现代分子生物技术的进展为改良植物种子蛋白质营养品质提供了有效的技术路线,目前已发展了几种在分子水平上改良作物蛋白质营养价值的方法,包括内源蛋白质序列的修饰、同源优质蛋白基因的过量表达、异源优质蛋白基因的转移和表达、人工合成新蛋白基因、以及增加游离的必需氨基酸的含量等.本文重点从上述5个方面综述近年来采用基因工程技术提高作物蛋白质营养品质的进展,并就其中可能存在的问题作了讨论.  相似文献
