Certain engineering construction case showed that it is efficient for avoiding cracks to control temperature difference between internal and external concrete within 25 , which ensuring the high construction quality and ray - shielding function of massive concrete 现结合某工程施工实例,将混凝土内外温差控制在25以内能有效防止裂缝出现,从而确保了混凝土的施工质量,达到了大体积混凝土防射线的效果。
The thermal control design of space camera by means of cad / cae / cat technology is described , technical problems on thermal optics of space camera , thermal control temperature index , thermal response and thermal control design are also discussed in this paper 摘要阐述了运用cad / cae / cat现代技术手段进行空间遥感相机热设计的技术路线,探讨了某空间遥感相机热光学性能、热控指标、空间环境下的热响应及热设计等技术问题。
Adopt far - infrared heating technology , with low hot loss , high efficiency , high precisely for control temperature , uniform heating . compared with drying cabinet or electric stove ; it can automatical control temperature , easy to operate , drying effect is very satisfied 采用了远红外辐射加热技术,与一般烘箱及热处理用的箱式电炉相比较,具有热损失小、效率高、控温精度高,加热均匀:能自动控温、一时结束、操作方便等优点,可达到十分满意的烘干效果。
That means the controlled temperature al1ow waving in a range in a period . when the change of the temperature indoor is out of the range we enacted , the system begin to regulatc . compensate the windage last time leave behind } before decide the heatsupply parameter for the next time 即允许被控室内温度在一段时间内存在一定幅度的波动,当室温变化幅度超过设定值时系统开始调节,在确定下一时间段的供热参数之前对上一时间段的遗留偏差在短时间内给予补偿。
