寓体于乐 体乐相融——记上海交通大学一堂室内体育课

上室内素质课时,如何调节和激发学生的情绪和乐趣?怎样使学生既能积极锻炼,又能陶冶情操,文明身心?又如何缓和因雨天而场地紧缺的矛盾?这是我们在体育教学中经常碰到的问题。上海交通大学在体育教学改革中,对如何解决这些矛盾作了新的探索,引人启迪。 该校体育教研室从大学生的生理。

论柳子寓言的地位与特点

柳宗元寓言标志着社会讽刺寓言的成熟,标志着寓言本体的独立。其寓体牢笼百态,其本体隐显结合,境界幽邃。

两只苍鹰 两个典型——《飞鸢操》、《笼鹰词》合读

Effect of Temperature Differentials on Condensers of Split-Type Air Conditioners in Apartment Buildings

Analyzing the effects of heat rejection from condensers of split-type air-conditioning units at lower-floors of MLABs （multi-level apartment buildings）, using field measurements to monitor environmental conditions and condenser operation, revealed increases in the inlet air temperature at the condensers at the upper floors, which in turn increased the power and energy requirements for these units and decreased their cooling capacities. Results indicated that a decrease of up to 16,000 tons in cooling capacity and an increase of up to 67.2 MW in the national peak load demand might be reached for a 4 ℃ temperature differential for Kuwait conditions. It is recommended that the condensers be placed in the wind pathway to minimize the impact of heat rejection and stack effect and to optimize the operation of split-type air-conditioning units, and that other factors regarding installation setup and location are investigated.
