The reason is that the thermal conductivity of the air is λ=0.022 kcal/mh℃, which is the lowest value among the common materials and the lower thermal conductivity of the air resulted in less thermal transfer through the natural convection including radiation.
Overall, the thermal conductivity tends to decrease as the foam ratio increases; however experimental errors are considered to have occurred because of the interruption between the gaps due to the cohesion of some materials and several collapsed gaps while infilling after mixing.

Design of Intelligent Underground Sound Bird Repellent System Based on Wireless Communication Network YIN Xijie1,a, LinJian2,b, SHAO Zengzhen2,c,* 1 School of Information and Technology, Shandong Women’s University, Jinan, 250002, China; 2 School of Information Science and Engineering, Shandong Normal University,Jinan,250014,China axijiesd@126.com, b512642360@qq.com, cshaozengzhen@163.com Key Words: intelligent bird repellent, wireless communication, short wave station Abstract: Aimed at problems nowadays existing in airport bird drive, an intelligent underground sound repellent system is designed.
The above bird repellent devices have some defects, which are shown in: 1) with large size, big height and hard material, they can’t be assembled close to the airport runway, thus weak in driving birds; 2) most of them adopt random driving method, and space-time cross relations between birds and the plane isn’t considered; 3) long time exposed to external environment, the device costs a lot in maintenance; 4) the device operates independently, thus effective linkage is hard to develop.

In summary, the digital strong motion records baseline drift is due to inaccurate response from the instrument, fatigue electromagnetic noise, sensor material, background noise and ground tilt or rotate and bring the pollution of ground vibration signal[12].
