建筑工程施工管理

本文以深圳新中桥工业园工程项目为例介绍了基于建设单位的建筑工程施工管理,具体从建筑工程施工管理的意义、内容和达到的效果几个方面来描述。并通过分析本项目施工管理过程中存在的问题,根据施工管理的发展方向提出相应措施,进而保证建筑工程施工的顺利进行。     

STUDY ON RESIDUES OF ~(14)C-CARBOFURAN IN MODEL RICE-FISH ECOSYSTEM

Residues of 14C- carbofuran were studied in model late- rice ecosystem (LRE) and early- rice ecosystem (ERE). The treatment consisted of two rates of the pesticide (1x) and 2.5x). At day 56 after application, 7.3% (1x) and 2.9% (2.5x) of the pesticide and its degradative products remained in the water of the LRE, and 1.8% (1x) and 2.4% (2.5x) of them remained in the water of the ERE. At harvest, 37.5% (LRE) and 24.0% (ERE) of the pesticide applied were detected in the upper layer of the soil; and 40.6% (LRE) and 26.9% (ERE) remained in the lower layer of the soil. The residues in the rice plants increased at the first stage, reached maximum levels during day 14 to 28 after application, and decreased thereafter. At harvest, residues in the stems and leaves in the two treatments (1x and 2.5x) were 3.91μ g/g and 7.78μ g/g (LRE) and 5.04 μg/g and 17.29 μ g/g (ERE) respectively. Residues in the ears were about 1/8 to 1/12 of that in the other parts of the plants. The pesticide residues in fish bodies in both experiments were also determined.     

水分含量对鲜湿米粉品质影响

研究不同水分含量对鲜湿米粉成品感官品质,蒸煮特性方面影响;并研究水分含量对鲜湿米粉储藏期内感官品质、微生物指标、蒸煮特性(蒸煮损失率和熟断条率)和酸度影响。结果表明,水分含量为65%鲜湿米粉成品感官评分最高;在储藏期内,随水分含量增加,鲜湿米粉感官品质变劣速度、微生物指标超标、蒸煮损失率和熟断条率及酸度增加也越快。经综合考虑,选鲜湿米粉最宜水分含量为65%。     

探索海岛岸线的保护与利用——以湛江市南三岛为例

人们在对岸线资源的并发利用过程中,总是比较难以协调保护和利用的矛盾,因此,协调好岸线资源的保护与利用的矛盾在海岸规划开发过程中十分重要。本文主要在前人已经取得的研究成果基础上,结合湛江市南三岛海岸线资源极其发展现状,分析了南三岛岸线的自然资源特征,并对其保护及开发利用进行初步的研究和探讨。     

高速铁路站前广场周边城市设计研究——以广深港客运专线东涌站为例

基于广深港客运专线东涌站的站场周边地区规划设计，通过分析该地区的功能定位、空间结构、交通组织、建筑高度、开发强度、开发空间等方面的问题，确定合理的发展模式及分期建设规划，同时也为我国高速铁路站点周边地区的建设积累经验。
