The expression of calculating the horizontal difference in temperatures t is provided . the equation of the super - length tall buildings with the temperature distribution is formulated , and also the relevant solving strategies are provided 给出了超长高层建筑结构在各种温度作用下温度变形、温度内力(应力)的数值范围、分布状况及在对比模型中各构件中温度内力、变形的变化情况,从中找出减小结构温度内力的方法。
Basing on the exergy analysis of the evaporation system the links which losing exergy most was found . the external losing exergy mainly concentrated in the consumption of second - degree vapor . the internal losing exergy mainly caused by the difference in temperature of heat conduction and concentrated heat 在对蒸发系统(火用)分析基础上,找到系统(火用)损的主要环节,即二次蒸汽的消耗引起的外部(火用)损、有效传热温差和浓缩热引起的内部(火用)损。
The thermal wave nondestructive testing technology based on emissivity of the object , it can find surface and subsurface flaws in the composites of airplane through measuring difference in temperature between flaws and materials by active heating methods and inspection system 摘要红外热波无损检测基于物体的热辐射特性,利用主动加热技术,通过相关的检测系统记录试件表面缺陷和基体材料由于不同热特性引起的温度差异,进而判定飞机复合材料表面及内部的损伤。
While the method of lagrange was used to optimize the system , the optimized flow was gained . the flow was appended jet pump behind the first effect and the second effect . by this means , the second - degree vapor was improved and internal losing exergy caused by the difference in temperature of heat conduction and concentrated heat was reduced 采用拉格朗日乘子法对氯化铵回收的三效降膜蒸发系统进行经济优化,得出三效降膜蒸发系统优化流程,即采用在第一、二效后增加热泵和真空蒸发的方法,提高了二次蒸汽的品位能,减少了由于传热温差和浓缩热引起内部(火用)损。
Cable - stayed bridge , difference in temperature , shrinkage and creep sophisticatedly affect the course of its construction . after closure , with the strength of concrete , the adjustable range of internal force and configuration is narrow . so , rigorous control of construction is the guarantee of achieving design objective 斜拉桥,施工过程中由于受温差、收缩、徐变等因素影响,再加上混凝土的强度不高,成桥后内力和线形可调的范围都较小,对施工过程的严格控制是实现设计成桥目标的保证。
