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。

It can be predicted from the results that the column effect of adsorption of gold by ion exchanger will be remarkably improved by increasing temperature.
由结果推测，温度升高，将显著提高离子交换法吸金过程的色谱柱效。

The equipment made by us of titanium, stainless steel, aluminum or plastics, mainly include column condenser ( heat exchanger ) ;
