NO elimination reactions are much complicated in the system of NO-CO-CO2-N2 with the existence of metallic oxides. Homogeneous reaction between NO and CO, reduction of NO by the lower valued metallic oxides, direct decomposition of NO as a catalytic reaction and catalytic reaction of NO/CO may all contribute in NO elimination.

金属氧化物存在条件下NO-CO-CO2-N2体系中，NO去除反应较为复杂，NO/CO气相直接反应、低价氧化物对NO的还原作用、金属氧化物对NO分解反应的催化作用及金属氧化物对NO/CO反应的催化作用等都可能存在。

Results: The evaluation at the middle of period of treatment: the variations of pulmonary rales, perpheral bloody white blood cells and the X-ray examination an chest of the two groups' patients wren similar, but the symptom of fever and character of respiratory tract's secretion of the patients in experiment group took turns for better obviously than the control group's, the rate of elimination for ineffective on 3 day of the experiment group was obviously lower than the matched control. The evaluation at the end of period of treatment: the total effectualness and elimination of bacterium of the experiment group were notably higher than the matched control, There were not any obvious untoward reaction.

The main reasons for the higher efficiency are the elimination of the water pump, the elimination of the water heat exchanger (which is a source of heat losses), and the phase change of the refrigerant in the ground itself, allowing a higher temperature gradient between loop and ground resulting in a higher rate of heat transfer.

为高效率的主要原因是水的泵，水的热交换（这是一个消除热损失的来源），以及本身在地面制冷剂相变，从而使一回路和地面之间的热传递率较高导致较高的温度梯度。
