But checked Chad engineering core column is fixed with aluminum alloy column, so will lose freedom scale effect, when heat bilges cold shrink large internal stress.
但是被检查的工程芯柱都与铝合金立柱固定，这样就会失去自由伸缩作用，当热胀冷缩时产生较大的内应力。
Common heat exchanger models are based on the theories of line heat source and column heat source.
常见的地下换热器传热模型的理论基础主要有线源理论和柱源理论两种。
