1) air temperature yearly variation amplitude
气温年变
1.
This paper has systematically studied the influence of three temperature loads,namely,cold wave,air temperature daily variation amplitude and air temperature yearly variation amplitude,on surface s.
课题组通过研制的仿真分析软件FZFX3D,考虑混凝土浇筑过程,以离开基础约束区一定距离的某个浇筑块为研究对象,系统研究寒潮、气温日变幅和气温年变幅等三种温度荷载对向家坝碾压混凝土纵向围堰表面应力的影响。
2) annual variation of air temperature
气温年变化
1.
Thermal stresses in sluices are analysed systematically by 3D FEM,including the stresses due to heat of hydration in construction period,the stresses due to annual variation of air temperature,and the stresses due to cold wave.
用三维有限元对水闸温度应力进行了系统的分析,包括施工期水化热引起的应力,气温年变化引起的应力及寒潮引起的应力,这3种温度应力单独作用都不会引起混凝土裂缝,但组合应力可能引起裂缝。
3) annual range of temperature
全年气温变化
4) annual mean temperature
年气温
1.
Wavelet analysis on annual mean temperature and rainfall change of Qaidam Basin during last 50 years;
柴达木盆地近50年来年气温、降水的小波分析
5) annual mean air temperature
年均气温
1.
Obvious differences were observed in the increasing rate of annual mean maximum air temperature,annual mean air temperature,and annual mean minimum temperature as well as the heat island effect in Ji\'nan,whereas negligible differences were found in Xi\'an.
10a-1的速率上升外,2个城市的气温指标均无明显变化趋势;1979—1998年间,2个城市则表现出显著的增温趋势,其中西安年均最高气温和年均气温的增加速率大于济南,济南年均最低气温的增加速率大于西安。
补充资料：气温年较差
一年中，最热月和最冷月的月平均气温的差值。一般是高纬地区大于低纬地区，大陆大于海洋。世界上气温年较差最大的地方是西伯利亚东北部的维尔霍扬斯克，达60°c以上。
