The research shows that the carbon absorption rate can be up to 90% approximately by using the pretreated carbon powder and precast blockpenetration method.
研究表明，经过预处理的碳粉，采用预制块压入法可使碳的吸收率稳定在90%左右。

Passive infrared penetration is poor, the human body easily block the infrared radiation not be receiving probe.
被动红外穿透力差，人体的红外辐射容易被遮挡，不易被探头接收。

The inlet pipe penetration into the vessel, the pressure drop across any block valves used. upstream of the venting device, and the inlet piping must be considered when determining these losses.
