温差作用 meaning in English
temperature effect
Examples
- The effects of seasonal difference in temperatureon super - length tall buildings
季节温差作用对超长高层建筑的影响 - ( 2 ) the change of ratio of spans has a great effect on the whole bridge under dead load and sunshine temperature differential . on the contrary , it has a smaller effect on the bridge under annual temperature change
( 2 )跨径比值变化，对主梁、桥墩在自重荷载与日温差作用下的受力有较大影响，而对主梁、桥墩在年温度变化荷载下的受力影响较小。 - In this paper i have done several worksuch as : coefficient of thermal expansion of frp sheet is larger different thanthat of the concrete . the interface of frp sheet reinforced concrete will producetemperature stress under the circumstance of temperature difference . i n order todesign the reinforced structure and evaluate safely , it is very significant toanalyse the interface temperature stress and to find the changing law of interfacetemperature stress
本文重点分析了frp片材补强混凝土梁界面温度应力分布理论,解决补强方面的一些工程问题,主要完成了以下几个方面的研究工作:首先, frp片材的热膨胀系数与混凝土的热膨胀系数相差较大,在环境温差作用下, frp片材补强混凝土界面将产生界面温度应力,正确分析界面温度应力和界面应力变化规律,对补强结构设计和安全评价具有重要的意义。 - Concludes that the undesired effect of temperature difference could not be eliminated just by the negative pressure difference between adjacent rooms , that the contaminant air exchange would increase about 50 % in the temperature difference of 2 than that in the temperature difference of 0 , and that such contamination could be reduced to about 1 / 31 ~ 1 / 16 with the help of buffer rooms
结果显示，温差作用是一般压差作用抵消不了的； 2温差时污染物交换量比0温差时增加50 %左右；缓冲室可对温差作用引起的污染物交换起到15 ~ 30倍的动态隔离作用。 - ( 2 ) the stress caused by heat of hydration during construction is mainly distributed in the beams , and girders and stress in slab was smaller ; during service process , the stress caused by difference in temperature in different seasons is mainly distributed in bottom components ; the stress caused by difference of inside and outside temperature is mainly distributed in peripheral components of building ; the stress caused by difference in temperature due to sunlight is mainly distributed in the components exposed to the sun . ( 3 ) the control methods brought forward such as setting the reasonable stripping time reducing cast temperature of concrete setting after - treatment joint inflicting prestress arranging steel for construction requirement and so on are effective and their application may be extended
在使用期，由季节温差作用引起的结构内力主要分布在底层构件上；由内外温差引起的内力主要分布在建筑物外围构件上；由日照温差引起内力主要分布在向阳面的构件上； ( 3 )在施工阶段，可采取使用导热性能较好的模板、合理设计拆模时间、降低浇筑温度等措施来减小水化热引起的结构内力；采用设置后浇带的措施来减小结构在整体降温情况下产生的温度内力。
