自从有地球有生命以来，在环球地形和环球温度产生了年夜量的厘革；
Since the creation of the Earth there have been many substantial changes in global terrain and global temperature;
大体积混凝土的截面尺寸较大，有荷载引起的可能性较小，但由于温度产生的变形对大体积混凝土却极为不利。
The section size of mass concrete is larger, the less likely to cause a load, but due to the temperature of deformation of mass concrete is extremely adverse.
当测量温度中使用电阻式温度检测器，励磁电流本身这个温度产生I 2r，或焦耳热化，产生一个比指示温度稍微高一点的温度标准。
When measuring temperature using an RTD, the excitation current itself produces I 2r, or Joule heating, producing an indicated temperature somewhat higher than the temperature being measured.
