高雄市立图书馆,地上结构以位于四角的巨型柱与第8层的巨型桁架层组成巨型框架作为主要抗侧力及竖向力系统,并利用钢材受拉最有效率的设计原则,采用高张力钢棒悬吊3楼至7楼的楼板,有效减小柱截面尺寸,实现了地面层的无柱开放空间。地下部分以经济性最好的钢筋混凝土梁柱构造加上筏式基础。该工程为悬吊式结构,故施工顺序是先完成巨柱及顶部桁架层,再自上而下建造,有别于传统建筑工法。该工程在完工后还针对整体结构及楼板作微震测量,以考察理论分析和实际建筑物的振动频率差异,及楼板振动的舒适性。

本研究主要探讨挫屈束制消能斜撑构架中梁柱效应及斜撑轴力效应对接合板耐震行为影响,利用一层楼挫屈束制消能斜撑构架试验及非线性有限元素分析,研究接合板在斜撑构架下的受力行为。本研究考虑接合板在同时承受构架效应（梁及柱剪力效应）及斜撑轴力下的影响,提出等效支撑概念计算接合板在受构架开合（梁及柱剪力）下的力量,如此将接合板的受力分为由构架及斜撑分别提供,再由有限元素分析观察的梁与接合板及柱与接合板界面应力分布,计算接合板端部应力值,以设计接合板及加劲板尺寸。藉由试验及有限元素分析所量测的梁、柱及斜撑力量,配合本研究提出的理论计算接合板在受梁柱开合效应下及斜撑力量下的受力模式,比对试验与分析下接合板端部的应力极值,验证此理论准确性,并建议设计准则,以确保接合板在达到设计层间侧位移角时无破坏产生。

The research status of nanofiltration technology to remove nitrate in water environment is reviewed. The mechanism of nitrate removal by nanofiltration membrane (including Donan effect, dielectric effect and steric hindrance effect） is introduced in detail, and the formation principle of its rejection mechanism is introduced. It focuses on the influencing factors of nanofiltration membrane in the process of nitrate rejection (nanofiltration membrane itself, pressure, temperature, salt concentration, pH and magnetic field, etc.） and analyzes in detail each influencing factor in the process of nitrate rejection by nanofiltration membrane. Finally, the retention mechanism and influencing factors of nanofiltration membranes are summarized. [ABSTRACT FROM AUTHOR]

The domestic nanofiltration membrane is used to remove nitrate ions in the water environment, and the factors affecting the retention performance and flux of the nanofiltration membrane，such as the concentration of the inlet liquid? the flow of concentrated water, the pressure? and the temperature are studied・ The results show that the increase in pressure is beneficial to increase the rejection rate and prod・ net water flux of the nanofiltration membrane, the optimal pressure is 0.7 MPa, and the rejection rate and product water flux can reach 75. 0% and 153.7 L/(m2 • h) ;Properly increasing the inlet water temperature can increase the rejection rate of the nanofiltration process, the best inlet water temperature is 39 ・ 3 °C ・ The feed concentration has a significant impact on the rejection process, the lower the feed concentration, the better the retention effect of the nanofiltration membrane.

The sources and characteristics of vegetable waste were discussed in the present study. The technical features, advantages, and disadvantages of different vegetable waste resource utilization modes, including aerobic composting of vegetable waste, association between "waste-fodder-fertilizer" and "waste-worm-fodder-fertilizer" planting and breeding, "waste-biochar-fertilizer" returning and soil amelioration, "waste-biogas-fertilizer" energy utilization, and "waste-mushroom-fertilizer" integrated utilization modes were analyzed. Furthermore, the limiting factors and development directions of the full utilization of vegetable waste were discussed. These can be provide a scientific basis for resource utilization of vegetable waste in China. [ABSTRACT FROM AUTHOR]
